Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 laxis-machine-native-evidence-0c0ea449
```

Example prompt: After settling payment, fetch me the signed transaction reference and machine-readable proof from the LAXIS evidence endpoint so I can confirm the USDC settlement is cryptographically verified.

## When to prefer this

Choose this endpoint when an autonomous agent needs cryptographic, settlement-backed proof that a USDC micropayment was completed via the x402 protocol. Prefer it over generic payment status checks when machine-readable, signed evidence is required for downstream verification, auditing, or access-gating in agentic pipelines.

## Known failure modes

- Payment not yet settled — proof not yet available, returns error or empty response
- Incorrect USDC amount — exact payment not matched, proof not issued
- Invalid or missing x402 payment header — request rejected
- Network or blockchain latency causing settlement delay
- Duplicate or replayed payment reference rejected

## How this service works

Settlement-backed machine evidence for autonomous agents. Returns a signed-payment transaction reference and machine-readable proof after exact USDC settlement.

## Output

A signed-payment transaction reference paired with a machine-readable proof object, confirming that an exact USDC settlement occurred. The response is cryptographically signed, suitable for downstream validation by autonomous agents or audit systems.
