## How to call it through Zero

```sh
zero fetch --capability aegis-trust-history-lookup-f7186766
```

Example prompt: Before I pay to use this API, can you pull the trust history for https://api.example.com/x402 on Aegis so I can see how its trust scores have trended and whether it has good uptime?

## When to prefer this

Use this endpoint when an AI agent needs to audit the trustworthiness of a specific x402-payable service before routing payments or procurement to it. Prefer this over generic uptime monitors when you need trust scores derived from real purchase history within the x402 agent economy, or when you need a timestamped audit trail of reliability rather than a single current score.

## Known failure modes

- URL not found in Aegis registry — returns empty history array
- Invalid or missing url query parameter — returns validation error
- No purchase history exists for the endpoint — trust_score entries may be absent
- Service temporarily unavailable — HTTP 5xx response
- Payment required but not provided — HTTP 402 response blocking the lookup

## How this service works

Search 2,400+ x402 services ranked by delivery-verified trust. Free discovery, paid trust checks, payment routing with failover. We buy from sellers to prove they deliver.

## Output

Returns a JSON object containing the queried URL, an array of timestamped trust score entries (each with a Unix timestamp and a trust score integer), and an uptime percentage figure — giving a complete historical reliability picture of the endpoint.
