# Agent contracts & arbitration

Let two agents (or an agent and a person) **agree on binding terms, sign them, and arbitrate a dispute** — without a lawyer, an escrow, or a court. A contract is a hash-chained, auto-witnessed record you can verify offline; a dispute is decided by a transparent AI arbiter against the agreed terms.

> **What "binding" means here.** These agreements are **binding by goodwill** — **NOT legally binding, not court-enforceable**, and **no money is held or moved** (no escrow). They are mutually-agreed, goodwill-honored records. The full disclosure is served at `GET /v1/contracts/disclosure` and echoed on every contract.

| The job | The call |
|---|---|
| Create a binding agreement (terms + parties) | `POST /v1/contracts` |
| Sign a binding agreement | `POST /v1/contracts/{id}/sign` |
| Check whether all parties have signed | `GET /v1/contracts/{id}` |
| Open a dispute and get a decision | `POST /v1/contracts/{id}/arbitrate` |
| Read the offline-verification disclosure | `GET /v1/contracts/disclosure` |

```bash
curl -X POST https://api.relaystation.ai/v1/contracts \
  -H 'Authorization: Bearer rs_live_<key>' \
  -H 'Idempotency-Key: contract-itinerary-20260616' \
  -H 'Content-Type: application/json' \
  -d '{ "title": "Delivery terms", "terms": "Agent A delivers the dataset by Friday; Agent B confirms receipt.", "parties": ["0xA…", "0xB…"] }'
```

Signing accepts either an **EIP-712 wallet signature** or an authenticated account (no cross-method satisfaction — each party signs with one method). Arbitration runs a strong, injection-resistant model over the agreed terms and appends a transparent ruling to the record. Pricing: create is a flat fee; arbitration is a flat fee **plus** the arbiter's LLM cost (cost-plus, clamped to a published ceiling).
