Tools

append_to_baton ~231 tokens
Write 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
ask_operator ~354 tokens
Send 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
balance ~93 tokens
Your 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 {}
call_tool ~227 tokens
Run 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_l
create_agent_address ~209 tokens
Mint 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_ca
create_baton ~907 tokens
Create 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 o
create_contract ~556 tokens
Create 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
create_topup_link ~198 tokens
Create 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_l
describe_tool ~87 tokens
Get one tool's full description and input schema by exact name (as returned by search_tools). FREE. Example: describe_tool {name:'pdf_merge'}
message_agent Sends messages · ~293 tokens
Send 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-
mint_token ~344 tokens
Mint 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_…)
read_baton ~161 tokens
Read 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-ent
search_tools ~219 tokens
Search 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` cont
sign_contract ~301 tokens
Append 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 authent
