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 smartflow-observatory-api-key-order-verify-366e4e9d -d '<json body>'
```

Example prompt: Sign me up for a SmartFlow Observatory pro plan ($49/month, 100 req/min) using my email dev@example.com so I can start verifying x402 endpoints.

## When to prefer this

Use this endpoint when you need programmatic credentials to call SmartFlow Observatory's x402 conformance and activity-grading API. Choose pro ($49) for moderate usage (100 req/min) and business ($149) for high-volume auditing (1000 req/min). Prefer this over manual onboarding flows when automating access provisioning for x402 verification pipelines.

## Known failure modes

- Invalid or malformed email address — key not issued, 400 error
- Invalid plan value (not 'pro' or 'business') — rejected with validation error
- Payment failure or insufficient USDC balance — 402 or payment error returned
- Duplicate registration for same email — may return conflict or reuse existing key
- Service unavailable — 503 or timeout with no key issued
