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 aircraft-report-faa-registry-changes-feed-729ca0a7
```

Example prompt: Show me all ownership changes recorded in the FAA aircraft registry for tail number N100 since 2025-01-01, up to 500 results per page.

## When to prefer this

Use this endpoint when you need a time-series view of FAA registry mutations — ownership transfers, deregistrations, status changes — rather than a point-in-time snapshot of a single aircraft. Ideal for compliance auditing, fleet monitoring pipelines, or detecting when a specific tail number changed hands. Prefer over the identity lookup endpoint when the question is 'what changed and when' rather than 'what is this aircraft right now'.

## Known failure modes

- Missing required input object returns 400 validation error
- Using both `date` and `since` simultaneously is disallowed and returns an error
- Invalid `kind` enum value returns 400
- Invalid date format (not YYYY-MM-DD) causes query failure
- Cursor from a different query context may produce unexpected results
- Exceeding page limit of 500 is silently clamped or returns error
- No results found returns empty changes array with has_more: false

## How this service works

FAA aircraft registry API for agents, paid per call with x402 (USDC on Base). MCP server: https://aircraft.report/mcp

## Output

A JSON object containing a `changes` array of registry change events, each with a `kind` (e.g. owner_changed, deregistered), `before` and `after` state snapshots, `fields` that changed, the `n_number`, and the `snapshot` date. Also includes `has_more` boolean and `next_cursor` string for pagination.
