## 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 x402-data-api-uptime-incidents-failed-apis-6af02aac
```

Example prompt: Show me up to 30 x402 APIs that were previously healthy but failed the latest uptime check — I want to see the paid ones first so I know which revenue-generating endpoints are currently broken.

## When to prefer this

Use this endpoint when you need to identify x402 marketplace APIs that are currently experiencing downtime or have failed their latest health check. Prefer this over the uptime-ranking endpoint when you specifically want to find broken or incident-flagged APIs rather than rank healthy ones. Ideal for building alerting systems, reliability dashboards, or vetting API sellers before integration.

## Known failure modes

- Invalid limit value (outside 1-50 range) may return an error or default
- Payment failure due to insufficient USDC balance ($0.002 per call)
- Empty result set if all monitored x402 APIs are currently healthy
- Stale data if the 6-hour uptime check cycle has not yet run

## How this service works

x402 APIs that were up before but failed our latest check, most paid first.

## Output

Returns a paginated list of x402 API listings that passed prior uptime checks but failed the most recent check, ordered by paid status first. Each result includes API details such as endpoint URL, pricing, seller origin, and incident metadata. Also includes a total count of current incidents.
