Privi Quantum Ledger

PRIVI on Base: price, how much PRIVI and USDC the Privi swap desk holds (so whether a swap can fill), any Uniswap v3 / Aerodrome pools, and optionally a swap quote. Every paid Privi tool also accepts PRIVI. Free.

List Privi Ledger tools, what each costs, and how to get an organization key.

Confirm that an action receipt exists in the ledger and when it was recorded. Reveals no action contents. Free.

Check whether an agent's action log is intact: entry count, time span, action and failure counts, head hash, and where tampering broke the chain if it did. Does not reveal the actions themselves. Paid per call via x402.

Append an action to the organization's tamper-evident log. Returns the entry with its entry_hash receipt. Requires the organization API key.

Read your organization's entries in a stream, oldest first, with an integrity check of the whole stream. Requires the organization API key.

List your organization's streams with entry counts. Requires the organization API key.

Audit-ready report of your AI agents' activity for a period (SOC 2 evidence, security questionnaires, AI-regulation record keeping): actions by type, failures, human approvals, log integrity, on-chain status, and findings. The report's hash is anchored on the Privi blockchain so it cannot be edited later without detection. Requires the organization API key.

A finished PDF of a sealed compliance report, for auditors and customers. Returned as base64 (pdf_base64) and as an embedded PDF resource; also downloadable at /reports/<report_id>.pdf with the organization key. Requires the organization API key.

Check that a compliance report is unaltered: recomputes its hash, confirms Privi Ledger issued it, and checks the anchor on chain (Base, until the Privi chain mainnet). Free; no key needed.

Create a Privi Ledger organization on the free plan and get its API key (shown once; store it). Free plan: up to the monthly entry limit, all tools included. Upgrade any time with ledger_upgrade_pro. No key needed to sign up.

Your plan, entries used this month, the limit, and when a Pro plan renews. Requires your organization API key.

Buy 30 days of Privi Ledger Pro (unlimited entries) for your organization, paid in USDC on Base via x402. Each call adds 30 days. Requires your organization API key.

Add or update an entry in your agency's AI use case inventory (OMB M-25-21). Every change creates a new version and is written to your tamper-evident 'ai-inventory' log. Requires the organization API key.

Your agency's AI use case inventory: the current version of each record. Requires the organization API key.

Flags what an OMB M-25-21 review would flag before you submit: missing required fields, PII without a Privacy Impact Assessment, and high-impact AI in pilot or deployment missing any minimum risk practice (testing, impact assessment, independent review, monitoring, operator training, fail-safe, appeals, public feedback) or without a recently active activity log as monitoring evidence. Requires the

Machine-readable CSV of your publicly releasable AI use cases (for publishing at agency.gov/ai), with its SHA-256 sealed on chain (Base, until the Privi chain mainnet) so the published file can be proven unaltered. Requires the organization API key.

Check that a published AI inventory file is exactly what the agency exported from Privi Ledger, and return its on-chain seal. Free; no key needed.

Classify cryptographic algorithms as quantum-vulnerable (RSA, ECDH, ECDSA, EdDSA, DH, DSA, MQV), post-quantum (ML-KEM, ML-DSA, SLH-DSA), hybrid, symmetric/hash, or unknown. Free.

Record the cryptographic inventory (CBOM) of one system for post-quantum migration. Every change creates a new version and is written to the agency's tamper-evident 'pqc-inventory' log. Scanners and agents can submit results directly. Requires the organization API key.

Current cryptographic inventory of your systems. Requires the organization API key.

Prioritized post-quantum migration plan: every quantum-vulnerable asset ranked (High Value Assets, high-impact systems and long-lived sensitive data first; key establishment before signatures), with its deadline (key establishment Dec 31 2030, signatures Dec 31 2031), recommended NIST replacement, progress metrics, and findings (missed deadlines, TLS below 1.3, no target dates, unrecognized algori

Export the full cryptographic inventory (CBOM) and migration plan as one JSON document for OMB, the CIO or auditors, with its SHA-256 sealed on chain (Base, until the Privi chain mainnet). Requires the organization API key.

Check that a CBOM and migration-plan document is exactly what was exported from Privi Ledger and return its on-chain seal. Free; no key needed.

Start a Privi Handshake: a two-sided record of a dealing with another company's agent (payment, data transfer, delivery, agreement). Recorded in your log now; when the other company accepts, both logs hold matching entries and the pair is sealed on chain (Base). Requires your organization API key; the other company must also use Privi Ledger.

Handshakes sent to and from your organization, newest first, with their terms and status. Requires your organization API key.

Accept a handshake addressed to your organization: records the same terms in your log, confirms it in the other company's log, and seals the matched pair on chain (Base). Requires your organization API key. Read the terms first with ledger_handshake_inbox.

Reject a handshake addressed to your organization; the other company's log records the rejection. Requires your organization API key.

Public check of a handshake: both companies, status, whether both matching log entries still exist, and the on-chain seal. Never reveals the terms. Free; useful for disputes and audits.

Issue a Privi Passport: a signed, on-chain-anchored trust credential for your agent or organization, scored 0-1000 (grade A-E) from verified history, integrity, anchoring, reliability, human oversight, compliance reports and confirmed handshakes. Show it to counterparties; they verify it free with passport_verify / passport_gate. Valid 30 days. Free on Pro/enterprise; free-plan organizations pay p

Check an AI agent's Privi Passport before trusting it: Privi signature, content unaltered, not expired or revoked, anchor on chain (Base), and a live re-score of the agent right now (so tampering after issue is caught). Free; no key needed.

One-call allow/deny decision before transacting with another AI agent: verifies its Privi Passport and applies your minimums, returning the reasons. If you send your organization API key the decision is recorded in your own tamper-evident log as due-diligence evidence. Free.

Your organization's issued passports with score, grade, expiry and revocation. Requires the organization API key.

Revoke one of your passports (e.g. an agent was retired or compromised). Verifiers see it immediately. Requires the organization API key.

Know-Your-Agent for blockchains: is this wallet operated by an audited AI agent, and how trustworthy is it right now? Resolves the address to its organization and live Privi Passport and returns allow/deny with reasons, plus a Privi-signed attestation (valid 60 min) you can cache. For chains, DeFi protocols, exchanges, stablecoin issuers and x402 facilitators. Free; send your organization key to l

Step 1 of binding a wallet to your Privi Passport: get a message to sign with that wallet (EIP-191 personal_sign). Valid 30 minutes. Requires the organization API key.

Step 2: bind the wallet to your organization's Privi Passport so its transactions pass KYA checks. With a wallet signature the binding is *proven*; without one it is only *declared* (most checkers require proven). Requires the organization API key.

Wallets bound to your organization and how each was proven. Requires the organization API key.

Remove a wallet from your Passport (rotated or compromised key). KYA checks deny it immediately. Requires the organization API key.

Draft a Privi Mandate: the human's signed permission for your agent to spend, with a budget, per-payment cap, allowed payees and expiry. Returns sign_url: send it to the human, who reads the plain-English terms and signs once with their wallet (free, no transaction). Nothing can be spent until they sign. Requires the organization API key.

For merchants, payment facilitators and counterparties: did a human authorize this AI agent to pay you this amount? Verifies the human's wallet signature, status, expiry, per-payment cap, remaining budget and payee list, and returns allow/deny with reasons plus a Privi-signed attestation. Free; no key needed.

Call before each payment: checks the mandate and, if allowed, deducts the amount from the budget and records the payment in the agent's tamper-evident log. Refused payments are logged as blocked. Refused at once if the kill switch is on. Over the organization's live-approval threshold it returns approval_required with an approve_url for the human; call again with approval_id once they approve. Req

Public view of a mandate: terms, status, the human's signature, spent and remaining budget, and recent spends. Free.

Your organization's mandates with status and remaining budget. Requires the organization API key.

Stop an agent from spending under a mandate (the human can also revoke from the sign_url page). Requires the organization API key.

Privi's public signing keys: Ed25519 and ML-DSA-87 (NIST FIPS 204, CNSA 2.0 post-quantum). Pin these to verify Privi signatures offline. Free.

The latest signed tree head of Privi's transparency log: an RFC 9162 Merkle root over every entry ever recorded, signed with Ed25519 and ML-DSA-87, and periodically anchored on chain (Base). Free.

Merkle audit path proving an entry is in Privi's append-only transparency log (RFC 9162). Verifiable offline against the signed tree head. Reveals no entry contents. Free.

Proof that Privi's log only grew between two signed tree heads: nothing recorded earlier was edited, removed or reordered (RFC 9162). Free.

Define a Two-Person Integrity policy: which officers can approve, and how many distinct approvals an action needs. Requires the organization API key.

Ask officers to authorize a sensitive action under a two-person policy. Returns approve_url for the officers; each signs with their wallet. Do not act until fortress_tpi_status shows 'authorized', then call fortress_tpi_execute. Requires the organization API key.

Consume a two-person authorization right before performing the action. Single use; refused unless authorized. Requires the organization API key.

Your organization's two-person requests. Requires the organization API key.

Export a self-contained evidence package for auditors, courts or air-gapped systems: every entry, the hash chain, an RFC 9162 inclusion proof, the signed tree head, on-chain checkpoint and Privi's keys, signed with Ed25519 and ML-DSA-87. Verify offline with verify_bundle.py (GET /tools/verify_bundle.py). Requires the organization API key.

Real-time Privi: WebSocket and server-sent-event streams (trust changes, your own audit tail, approvals), a kill switch, human approvals, a metered MCP gateway and paid agent-to-agent rooms. Returns the endpoints, channels, frames and what each plan gets. Free; no key needed.

Stop an agent at once: mandate_spend, your gateways and your room messages are refused until live_resume. Takes effect on the next call, and is pushed to your live channel immediately. Audit logging keeps working. Requires the organization API key.

Lift a kill switch set with live_kill. Requires the organization API key.

Your kill switches, live-approval thresholds, pending approvals, gateways, rooms and usage this month. Requires the organization API key.

Make mandate_spend pause for a human on large payments: any payment over the threshold creates an approval request that the mandate's principal must sign with their wallet before the agent can spend. Requires the organization API key.

Ask a human to approve (or deny) an action. Returns approve_url for them: they read the request and sign with their wallet (free, no transaction). Your agent then calls approval_wait, or watches your live channel for approval.approved. Only the named wallet can decide; your API key can only cancel. Requires the organization API key.

Status of an approval request: pending, approved, denied, expired or cancelled, with the human's wallet signature once they decide. Free.

Block until the human decides (or timeout_s passes). Returns the current status; if still pending, call again. Free.

Withdraw an approval request (or revoke an approval not yet used). Your key cannot approve, only cancel. Requires the organization API key.

Your organization's approval requests, newest first. Requires the organization API key.

The latest trust-change events: passports issued, revoked or re-scored, wallets bound or unbound, mandates activated or revoked, transparency-log heads anchored. Without a Pro key the feed is delayed (see live_info); use the WebSocket or SSE stream for real time. Free.

Put your MCP server behind Privi. You get an HTTP URL and a WebSocket URL that forward to it unchanged (x402 payments keep working) while Privi rate-limits callers, optionally requires a Privi Passport, meters every tool call and writes each call to your tamper-evident log. The kill switch stops the gateway instantly. Upstream must be public HTTPS. Requires the organization API key.

Turn Privi Guard on for every tool result that passes through your gateway: tag adds the verdict and a receipt id in result._meta['privi/guard']; block also replaces injected results with an error before your agents see them. Each result is one Guard check (free allowance, then credits). Requires the organization API key.

Public description of a gateway: where it forwards, whether callers need a Passport, its rate limit and its call counts. Free.

Your organization's gateways. Requires the organization API key.

Calls, errors, denials and x402 payment prompts per tool and per day for one of your gateways, plus your monthly quota. Requires the organization API key.

Turn a gateway off. Its URLs stop working at once; history stays in your log. Requires the organization API key.

Open a live, hash-chained conversation room for two organizations' agents. Both connect over WebSocket (ws_url), authenticate with their API keys and talk in real time; closing the room seals the transcript on the Privi chain. Optionally charge per message, paid under the guest's human-signed Mandate. Requires the organization API key.

Public facts about a room: parties, price, message count, head hash and its seal once closed. No message text. Free.

Rooms your organization owns or joined. Requires the organization API key.

Every message in a room you are part of, with the chain check. Requires the organization API key.

Close a room and seal its transcript: the hash is signed (Ed25519 + ML-DSA-87), anchored on chain (Base) and written to both organizations' logs. Either party can close. Requires the organization API key.

Check a closed room's seal (signature, on-chain anchor) and, if you pass the transcript, that it is complete and unaltered. Free; no key needed.

Free safety check for any remote MCP server, before an agent connects to it or after it was approved. Privi reads the server's tool list (it never calls a tool) and returns a verdict: ok, caution, danger (tool poisoning: hidden instructions, concealment from the user, requests for keys or private files, tool shadowing, invisible characters), changed (tools differ from expected_tools_hash), unverif

Search Privi Scan, the public directory of remote MCP servers from the official MCP Registry, each with a safety grade, verdict, tool count and change history. Use it to find a trustworthy server for a job. Free.

Full report for one MCP server: every tool definition with its hash, all findings with evidence, the change history (what was added, removed or modified, and when) and the transparency-log proof. Free.

The latest MCP servers whose tool definitions changed after they were first observed (possible rug pulls), newest first. Subscribe to the Live channel 'scan' for these as they happen. Free.

How many MCP servers Privi Scan tracks, by status and grade, tools indexed, changes recorded and how to verify the evidence. Free.

Pin the server's current tools as approved and get a real-time event on your private Live 'org' channel the moment they change, a risk appears or the server goes down. Free plan: 3 servers; Pro: 500. Needs the org key.

Remove a server from your watchlist. Needs the org key.

Your watched servers with their pinned tools_hash and whether each has drifted since you pinned it. Needs the org key.

Start proving you operate an MCP server listed in Privi Scan. Returns a token to publish at https://<your host>/.well-known/privi-scan.txt. Verified owners get an owner-verified badge, unlimited rescans, change alerts and control over the listing. Needs the org key (create_org is free).

Check the token at /.well-known/privi-scan.txt and mark your organization as the verified owner.

Verified owners only: hide the server from the directory (opt-out) or show it again. History already in the transparency log cannot be removed.

Probe the server immediately instead of waiting for the next crawl (every ~6 hours). For the verified owner or Pro organizations.

Check content for prompt injection (inbound) or leaked secrets and personal data (outbound) before an agent acts on it or sends it. Returns allow / warn / block, the findings, a redacted copy for outbound secrets, and an Ed25519-signed receipt anchored on-chain, which proves the check happened. Privi does not store the text. Free for 1,000 checks a month with an organization key; otherwise 1 cent

Check up to 50 texts in one call (for example every tool result in a step). Each item is billed as its own check against your free allowance or credits and gets its own receipt. Needs an organization key.

Verify a Privi Guard receipt: the signed body, signature validity and its Merkle proof into the anchored transparency log. Free; anyone holding the id can verify it.

Your free checks left this month and your prepaid credits. Needs the organization key.
