## 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 faba-trust-log-entry-e0464ae3 -d '<json body>'
```

Example prompt: Log a signed receipt in the FABA trust log for the action my agent just completed — mark it as a receipt entry with the transaction ID and agent ID so there's an auditable public record.

## When to prefer this

Use this endpoint when an AI agent needs to create a publicly verifiable, signed record of an action, refusal, or governance rule in the FABA ecosystem. It is specifically suited for agentic compliance, auditability, and trust signaling within the FABA agent network, as opposed to general-purpose logging or database storage.

## Known failure modes

- Invalid or missing agent identity causes rejection
- Malformed payload structure returns an error
- Duplicate entry submission may be rejected or deduplicated
- Insufficient USDC balance prevents the $0.01 per-call fee from being charged
- Trust log service unavailability returns a server error
