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 oblique-markets-x402-facilitator-health-check-93dd7f2a
```

Example prompt: Can you check whether the x402 payment facilitators — Dexter and Coinbase CDP — are healthy and reachable right now, and tell me their HTTP status and response latency?

## When to prefer this

Use this endpoint when you need to confirm x402 payment infrastructure is operational before initiating payments through Oblique Markets, when diagnosing payment failures, or when you need to know which payment kinds, schemes, and networks are currently supported by the Dexter facilitator.

## Known failure modes

- Facilitator is down — returns non-200 status for Dexter or Coinbase CDP
- High latency indicating facilitator degradation
- Timeout if a facilitator is completely unreachable
- Partial health if only one of the two facilitators is reachable

## How this service works

Use when an agent needs x402 facilitator health. Returns Live health probe of the two most-used x402 facilitators: supported kinds, schemes and networks from one, reachability with HTTP status and latency from the other (the one this service settles through on Base and Solana). $0.003.

## Output

Returns HTTP status codes and measured latency for both the Dexter facilitator (including its supported coverage: payment kinds, schemes, and networks) and Coinbase CDP, giving a real-time snapshot of x402 payment infrastructure health.
