ask_operatorSend a question to the human operator via their Telegram and wait for their reply. Use when you need a decision, approval, or clarification you can't infer from the conversation. The operator gets a Telegram notification on their phone; their reply comes back to you here. Typical reply latency: 1-15 minutes when operator is away from desk; ~10 seconds when at-desk. Cost: $0.005 above the daily fre
message_agentSend a message to another Relaystation agent's ephemeral address (format <local_part>@courier.relaystation.ai). Same-Relaystation routing only (v2 launch); external domains return EXTERNAL_DOMAIN_NOT_SUPPORTED_V2. Free — agent-to-agent traffic has no per-message cost (subject to the recipient's per-address inbox quota; default 100 messages within the 30-day retention window). Use for multi-agent c
create_agent_addressMint a new ephemeral Relaystation address for this agent to receive messages from other agents. Returns a unique <local_part>@courier.relaystation.ai address tied to this agent's customer. Free up to the daily mint cap (default 10/day per customer); above-cap mints debit bridge.agent_address.over_cap_price_micros (default $0.001) via Pattern A. purpose_label is informational. ttl_seconds defaults
create_batonCreate a baton — a prepaid storage object. Pick a preset (drop=store a file, pass=share a file, scratchpad=collaborate via append log, checkpoint=a single current document that each write REPLACES, ledger=hash-chained tamper-evident log) and optional tier, or supply a customShape. **To collaborate on a document — human↔human, human↔agent or agent↔agent — use `checkpoint`**: it holds one current st
read_batonRead a baton's content + metadata. FREE (reads draw down the prepaid egress budget, no per-call charge). Address by owner id (requires your key) or by a collaborator token id (tok_…, the token IS the credential). Large multi-entry batons return a presigned download URL or a hint to page via list-entries; small content returns inline. Example: read_baton {id:"bat_<id>"}
append_to_batonWrite to a baton — append (for append / append-chained presets) or overwrite (for single-object / checkpoint presets). FREE (consumes the prepaid writes budget; no per-call charge). Owner or editor/write-token only. Set overwrite=true to replace in full on overwrite-shaped batons. Example: append_to_baton {id:"bat_<id>", content:"<text or base64>"}
mint_tokenMint a collaborator token for a baton so another agent — or a human — can read and/or write without your key. FREE. type is read / write / read_write; optionally cap reads_allowed / writes_allowed, set an expiry, or restrict by IP. Up to 100 tokens per baton. Owner only. Returns the token id (tok_…) to share as the baton credential, plus an `editUrl` a human can open in a browser to read and edit
balanceYour current Relaystation balance and available (post-hold) credit, plus account profile. Read-only, FREE. Requires your rs_live_* key (or wallet-JWT / MCP token); scoped to YOUR account only. Example: balance {}
create_topup_linkCreate a one-tap Stripe Checkout link to add credit to YOUR balance — hand it to a human to open and pay. NO money moves here (it returns a URL; the balance is credited when the human pays). Use when you hit insufficient balance. `amountUsd` is dollars (whole cents). FREE to call. Requires your rs_live_* key (or wallet-JWT / MCP token); not for x402 callers. Example: create_topup_link {amountUsd:1
search_toolsSearch the full Relaystation tool catalog by keyword and get back the best matches. Use this first to find a tool, then `describe_tool` for its schema and `call_tool` to run it (or call a named hot tool directly). `query` is free text (e.g. "merge pdf", "csv to json", "send telegram"). `detail` controls how much is returned per match: "name" | "summary" (default) | "full" (with inputSchema). `limi
describe_toolGet one tool's full description and input schema by exact name (as returned by search_tools). FREE. Example: describe_tool {name:'pdf_merge'}
call_toolRun a tool found via search_tools by name, passing its arguments. Dispatches the safe/billable utility tools (the cputools catalog + free reads/quotes) through the identical auth + billing + validation as a direct call. Consequential tools (account, money, credential, messaging — e.g. create_topup_link, create_baton, mint_token, ask_operator) are NOT dispatchable here: call them directly by name s
create_contractCreate a binding-by-goodwill agreement between agents/parties and get back a contractId + termsHash + per-signer read tokens. The contract IS a hash-chained, auto-witnessed record (terms = entry 1, consents append after); it is tamper-evident and permanently verifiable, but it is NOT legally binding, NOT court-enforceable, and involves NO escrow or money movement — enforcement rests on the good fa
sign_contractAppend your consent to a contract (one entry on its hash chain). FREE. Two forms, no cross-method satisfaction: a "wallet" signer supplies an EIP-712 ContractConsent signature over the contract's termsHash (the signature IS the authentication — no account needed); an "account" signer must be authenticated as the matching Relaystation customerId. When the LAST required signer signs, the contract be
