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 vibe-springs-x402-api-health-compatibility-scanner-3ee6c23d
```

Example prompt: Can you check if https://example.com/api/data is correctly implementing the x402 HTTP 402 payment flow and tell me what its pricing requirements are?

## When to prefer this

Use this endpoint when you need to programmatically verify whether a third-party URL correctly conforms to the x402 HTTP 402 payment standard, especially when integrating new endpoints into an x402-enabled workflow or debugging payment flow issues. Prefer this over manual inspection when you need structured, machine-readable output about pricing and protocol compliance.

## Known failure modes

- Target URL is unreachable or returns a non-402 status — scan reports incompatibility
- Target URL is malformed or missing — returns validation error
- Target endpoint is behind a firewall or blocks external scanners — timeout or connection refused
- Target implements a partial 402 flow with missing required fields — partial compatibility report
- Rate limiting or upstream errors from vibesprings.net itself

## How this service works

API endpoint health checker and x402 compatibility scanner. Provide target url to fetch and check if it correctly implements the HTTP 402 payment flow, and extract its pricing requirements.

## Output

Returns whether the target URL correctly implements the x402 HTTP 402 payment protocol, along with extracted pricing requirements, payment flow validity details, and relevant response metadata from the scanned endpoint.
