## 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 phoenix-zero-pricing-43d2ce7e -d '<json body>'
```

Example prompt: What's the current Phoenix Zero x402 call price right now — is there a surge multiplier active from any sequencer stall or MEV storm?

## When to prefer this

Use this endpoint when you need to check the real-time cost of Phoenix Zero x402 API calls before executing them, especially in automated workflows where budget control matters or when network conditions (sequencer stalls, MEV storms) could trigger a 10x price surge. Prefer this over static price assumptions whenever reliability of cost estimation is critical.

## Known failure modes

- Service unavailable if the Phoenix Zero backend is down — returns 5xx error
- Stale pricing data if internal oracle feed is lagging behind real-time network conditions
- Unexpected surge multiplier value if a new event type is not yet categorized
- Rate limiting or 402 payment required if the caller has not paid the per-call fee

## Output

Returns the current price per API call in USDC along with the active surge multiplier (1x baseline or 10x during sequencer stalls or MEV storms), enabling callers to assess cost before submitting x402-priced requests.
