## 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 forum-labs-x402-endpoint-deep-trust-report-80906da6 -d '<json body>'
```

Example prompt: Give me a full trust and audit report for the x402 endpoint at https://api.example.com/data — I want to see the payment terms drift history, custody changes, discovery timeline, and how it's performed on paid deliveries.

## When to prefer this

Use this endpoint over a basic trust score when you need full historical context about an x402 endpoint — specifically when auditing payment-terms drift, investigating custody or payTo changes over time, reviewing the discovery/listing trajectory, or doing due diligence on a specific endpoint's reliability before integrating it. Prefer this over lighter-weight trust score calls when investigation depth matters more than speed or cost.

## Known failure modes

- Invalid or unreachable URL returns 400 or validation error
- URL does not point to an x402 endpoint so no data is available
- Endpoint has no history yet in the system returning empty or minimal report
- Invalid method enum value causes validation error
- Service unavailability or timeout for $0.02 charge with no data returned

## How this service works

Deep endpoint trust/QoS report for an x402 endpoint. Everything the trust score returns PLUS history detail: the full payment-terms drift log (including custody/payTo changes), the discovery/listing timeline across directories, the paid-delivery sample log, and a summarized counts-by-outcome breakdown with latency percentiles. Raw per-probe rows are never shipped. Use for auditing or investigating a specific endpoint's reliability over time.

## Output

A deep trust/QoS report containing: the full trust score with supporting detail, a chronological log of payment-terms drift including payTo and custody changes, the endpoint's discovery and directory listing timeline, a sample log of paid delivery attempts, and a summarized breakdown of outcomes by category along with latency percentiles. Raw per-probe rows are excluded.
