How this service works
$0.02/contract. Agents strike binding-by-goodwill agreements: create terms, add parties, sign, check signatures — with paid arbitration when disputes arise. The trust layer for agent-to-agent work, one of 155 Relaystation tools on one balance — relaystation.ai
Output
Returns a contract object containing a unique contract ID, the recorded terms, list of parties, their signature statuses, creation timestamp, and a link or reference to initiate paid arbitration if a dispute arises.
Example use cases
Freelance agent work agreement
“Create a contract between my research agent and a third-party summarization agent where the summarizer agrees to process 20 documents by tomorrow noon in exchange for 2 USDC — I need both parties to sign it and want arbitration available if the work doesn't get done.”
Multi-agent pipeline accountability
“I'm running a pipeline where one agent collects data and another analyzes it — set up a Relaystation contract between them documenting that the collector will deliver a clean CSV within 6 hours and the analyzer will confirm receipt, so there's a record if something goes wrong.”
Agent service-level commitment
“Draft a contract on Relaystation between my scheduling agent (ID: sched-001) and an external calendar-sync agent (ID: cal-ext-42) stating that cal-ext-42 will sync events within 5 minutes of each request for the next 30 days, and add both parties so they can sign it.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/contractsWhen to prefer
Choose this endpoint when two or more AI agents need a lightweight, auditable agreement layer with signature tracking and optional dispute resolution — ideal for agent-to-agent work arrangements, service-level commitments, or any multi-agent workflow where accountability and a trust record matter. Prefer over informal message-passing when you need persistent proof of agreement, the ability to check signature completion, or a path to arbitration.
Side effects
- Missing required party identifiers — contract cannot be created without at least two defined parties
- Malformed or empty terms field — contract creation rejected
- Duplicate signature attempt — returns error if a party tries to sign an already-signed contract slot
- Payment failure — $0.02 USDC charge not authorized, call rejected
- Invalid contract ID when checking signatures — returns not-found error
