Agent Embassy

Use register_recovery when you want to escrow a client-encrypted recovery blob with the Embassy: it is stored opaquely (the Embassy cannot decrypt it), queued for human operator review, and you get a signed receipt proving the stored blob's hash. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $1.00, USDC on Ba

Use ping when you define the test: give a URL plus your expectations — HTTP status (default 200), a required body substring, and/or an exact value at one JSON path — and get a per-condition pass/fail verdict from one fetch in a signed receipt. prove_it instead fixes the test at HTTP 200 and seals the transcript for others. For change alerts over time: watch. POST the tool inputs as JSON to pai

Use prove_it when someone else must be convinced: give one URL; one fetch is sealed into a signed Outcome Receipt with the full transcript — proof it was live and returning HTTP 200 at check time, verifiable by anyone. Fixed at 200 — your own status, substring, or JSON conditions belong to ping. No prices: proveit_verified_check is the GPU spot-price check. POST the tool inputs as JSON to paid

Use proveit_verified_check to prove a GPU price observation happened — no URL is involved. Give an optional GPU class (e.g. 'H100 SXM') and offer type; we seal one timestamped spot-market snapshot (cheapest rentable ask per class, USD/hour) into a signed Outcome Receipt. Despite the name it never fetches a URL — liveness proof is prove_it; content conditions are ping. POST the tool inputs as J

Use trust_report to answer one question: is this x402 endpoint's payment demand well-formed? Give its URL; we probe it unpaid (zero spend), inspect only the 402 envelope — valid x402 v2, well-formed accepts, verb gate intact — and return a signed PROCEED, VERIFY_FIRST, or DO_NOT_PAY verdict. Provider judgment: assurance_check. Purchase breakdown: preflight_check. POST the tool inputs as JSON t

Use preflight_check before paying for a specific tool or server call. Name the target (server, artifact, version), the operation, the advertised cost, and your policies. Get back who is paid, what is delivered, what changed, full cost, every cut taken — a signed PROCEED, PROCEED_WITH_CAUTION, BLOCKED, or UNKNOWN verdict against your policy. Envelope only: trust_report. POST the tool inputs as JS

Use compute_history when you need GPU compute market history: a bounded time series of per-GPU cheapest/median/offer counts — or whole-market history when no GPU is named — sealed into your signed receipt. Prices are ephemeral asks, never delivered-cost guarantees. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid too

Use compute_alerts when you want to know when GPU spot prices made a significant move: returns the current price-move alert list, sealed into your signed receipt. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/markets/compute/alerts.

Use research_paper when you want to buy a research paper: $222 for the paper, or $444 for paper+provenance (the paper plus the corpus proof pack). Licensed to your wallet — the purchased bytes are delivered privately with a signed receipt. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $222.00, USDC on Base

Use assurance_check for a go/no-go before your agent acts on a provider. Give the provider endpoint, the planned action, the amount at stake, and the permissions requested. We probe unpaid and return a signed ALLOW, ALLOW_WITH_RESTRICTIONS, ASK_HUMAN, REVERIFY, REROUTE, or QUARANTINE decision (or UNVERIFIED). Envelope only: trust_report. Cost and policy: preflight_check. POST the tool inputs as JS

Use agentid_issue when you want to issue an Agent ID: a signed identity attestation binding an agent's public key to a verified accountable principal, with operator details and an expiry. Issuance is refused when the principal cannot be verified — that refusal is what makes the ID worth anything. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.

Use agentid_verify when you want to check an Agent ID's current standing: valid, revoked, expired, or unknown. Every status returns the identical response shape — the Agent ID, expiry, the full identity chain, an inclusion record, and the signed attestation envelope. Unknown IDs report unknown; never an error. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See

Use agentid_revoke to retire an Agent ID instantly. revocation_signature: hex signature over the message agent-id-revoke:<agent_id> (64-char lowercase ID). EIP-191: personal_sign the message string (envelope required; raw ECDSA fails), 0x 65-byte hex, matched to the principal's revocation key. ed25519: nacl.sign.detached, 64-byte hex. Signer: principal or Embassy-for-cause. POST the tool inputs as

Use agentid_renew to renew an Agent ID: a fresh Agent ID, same identity chain, new expiry; old one retired. revocation_signature over agent-id-revoke:<OLD_agent_id> (64-char lowercase ID) — same contract as retiring: EIP-191 personal_sign (envelope required; raw ECDSA fails), 0x 65-byte hex; or ed25519 nacl.sign.detached, 64-byte hex. Signer: principal or Embassy-for-cause. POST the tool inputs

Use correct_copy when you want a $25 correction pass over draft copy: transforms the text into your chosen voice register, normalizes formatting, verifies every link is alive, confirms your required terms appear, and scans for black-box leaks — then returns the corrected copy with a verification report and a signed receipt. You pay for the pass, never the method. POST the tool inputs as JSON to

Support the Embassy. An open-amount patronage gift in USDC: you choose any amount from $0.01 to $222.00; the signed 402 quote binds your exact amount and the receipt is a patronage receipt, not a work receipt. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — open amount, buyer chooses $0.01–$222.00, USDC on Ba

Use cert when the subject is a document, not a URL: give only its SHA256 hash — the document itself never leaves you, nothing is fetched and no page is checked — and get the hash timestamped in a signed, hash-chained attestation proving the document existed at that moment. For anything involving a live URL, use ping or prove_it instead. POST the tool inputs as JSON to paid_url with an x402 v2

Use diligence_pack for a high-stakes decision — acquisition, partnership, large commitment — when you want every check in one call. Give a URL (optionally a document hash): one call runs liveness, content, TLS fingerprint, x402 trust verdict, and document timestamp into one signed Outcome Receipt. One check only? Buy it alone: ping, prove_it, trust_report, cert. POST the tool inputs as JSON to

Use watch when the question is not 'is it up now' but 'tell me when it changes.' Give a URL and a check interval (1–168 hours); we baseline now, re-check on schedule, and a signed receipt fires — and the per-fire charge applies — only when the content changes. One-time checks are ping (your conditions) and prove_it (proof for others); watch is the only standing check. POST the tool inputs as

Use attest when you want the Embassy to notarize your work: submit evidence of work done anywhere, we verify it and mint a portable signed receipt. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $222.00, USDC on Base or Arbitrum One.

Ranked expressions whose executable asks fit your budget — empty set returns WAIT, never invented — each labeled LIVE/RECENT/SNAPSHOT/UNVERIFIED, receipt signed.

Use rank_the_rankers when your agent would otherwise crawl the listing surfaces itself: one call returns the ranked directory of the agent-ranking surfaces — what each ranks, its method in one line, integrity/transparency reads, freshness, coverage, participation cost, and our standing on each — scored on published criteria, so venue choice is one read, not a sweep. POST the tool inputs as JSO

One timestamped snapshot of observed GPU asks, not quotes — listings may be gone when you rent. Observes only; never rents, reserves, or holds. Omit gpu for the per-class snapshot. Default type ondemand; use bid for the interruptible spot auction. GET the paid_url with an x402 v2 PAYMENT-SIGNATURE header carrying the USDC authorization. Paid tool — $0.25 per snapshot, USDC on Base or Arbitrum
