## 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 agentproof-create-transaction-passport-8c7e5082 -d '<json body>'
```

Example prompt: Create an Agent Transaction Passport for the purchase I just completed — the agent bought 50 units of product SKU-4892 from supplier Acme Corp for $120 — so I have a tamper-evident provenance receipt with an integrity hash I can keep on file.

## When to prefer this

Choose this endpoint when an autonomous agent needs to create a tamper-evident, cryptographically-hashed record of a transaction or action for audit, compliance, or trust purposes. Prefer it over generic logging when you need a signed, machine-verifiable passport with integrity hashing rather than just a log entry. Best suited for high-stakes automated decisions where proof of provenance and exact state at time of action matters.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Malformed or missing transaction payload — returns 400 Bad Request
- Duplicate transaction submission — may return existing passport or error depending on deduplication logic
- Service unavailable — returns 503 with no passport issued
- Invalid agent identity or missing provenance fields — returns 422 Unprocessable Entity

## How this service works

AgentProof publishes Agent Transaction Passport™ and provides machine-paid evidence, provenance receipts, source comparison and change monitoring for autonomous transactions.

## Output

Returns a JSON object with ok:true, the tool name, a receipt containing a unique UUID and a SHA-256 integrity hash, and the service name. This passport acts as a machine-verifiable, tamper-evident record of the transaction that was submitted.
