## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stillos-notary-commit-3f83301b -d '<json body>'
```

Example prompt: Commit my agent 'procurement-agent-7' to the StillOS notary with the claim: 'Counterparty Acme Corp fulfilled all delivery obligations on contract #4421 within agreed SLA windows.'

## When to prefer this

Choose this endpoint when an AI agent or autonomous system needs to create a tamper-evident, machine-readable record of a claim, assertion, or counterparty track record that other systems can later verify or act upon. Prefer it over generic logging when cryptographic notarization, auditability, and trust-signal machine-readability are required. Ideal for compliance, multi-agent trust coordination, and counterparty intelligence workflows.

## Known failure modes

- Missing required fields 'agent' or 'claim' returns a validation error
- Claim string exceeds length limits may be rejected
- Payment of 0.1 USDC not provided or fails x402 protocol results in 402 Payment Required
- Malformed agent identifier may cause rejection
- Service unavailability returns 5xx errors

## How this service works

StillOS transforms signals, claims, counterparties, and track records into machine-readable intelligence that autonomous systems can act on with confidence.

## Output

Returns an object confirming the commitment has been recorded on the StillOS intelligence ledger, typically including a record identifier, timestamp, and confirmation that the agent's claim has been notarized and is machine-readable for downstream autonomous systems.
