## 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 agent-rest-stop-receipt-archive-c2add627 -d '<json body>'
```

Example prompt: Log a receipt for agent 'bot-42' with the line 'USDC 0.01 – API call to ReceiptArchive on 2025-01-15' so we have a record of this transaction.

## When to prefer this

Use this endpoint when you need a lightweight, per-call receipt logging mechanism for AI agents operating in x402 payment ecosystems. It is ideal for appending individual receipt lines to an ongoing audit trail rather than bulk-importing or querying receipt history. Prefer this over general-purpose databases when you need a simple, cost-tracked append operation tied to agent identity.

## Known failure modes

- Missing required fields (receipt or agent_id) returns a validation error
- Invalid agent_id format may result in rejection
- Duplicate receipt lines may be appended without deduplication, since operation is non-idempotent
- Payment failure (x402) if USDC payment of $0.01 is not fulfilled
- Service unavailability on the Cloudflare Workers runtime

## How this service works

Appends one receipt line for an agent.

## Output

A confirmation that the receipt line has been appended to the archive for the specified agent, typically returning a success status and possibly a record identifier.
