## 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 routing-check-9b1ff4d4
```

Example prompt: Can you run a routing check for a Base HTTP GET request using routing group 'groupA' and routing selector 'sel1', and tell me whether it comes back as ok?

## When to prefer this

Use this endpoint when you need a lightweight, single-call check to confirm that a Base network HTTP GET request will route correctly given a specific routing group and selector. Prefer this over heavier workflow or receipt endpoints when you only need a boolean ok/status signal and not a full audit trail or receipt. Ideal for pre-flight checks or health monitoring in Base-integrated pipelines.

## Known failure modes

- Missing required query parameters 'a' (routing group) or 'calc)' (routing selector) results in a validation error
- Invalid or unrecognized routing group/selector combination may return ok: false with an error status string
- x402 payment not included or insufficient funds results in a 402 Payment Required response before the check is performed
- Cloudflare tunnel downtime may cause intermittent 502/503 errors
- Malformed input type (not 'http') or method (not 'GET') rejected by schema validation

## How this service works

Returns a compact routing check for a Base request.

## Output

Returns a JSON object with a boolean 'ok' field indicating whether routing succeeded, and a 'status' string describing the routing outcome. The response is compact and fast, designed for quick validation checks.
