## 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 api-myceliasignal-com-eb46ac98
```

Example prompt: Fetch me the latest US PCE inflation reading with a cryptographic Ed25519 signature so I can verify it's authentic before using it in my application.

## When to prefer this

Use this endpoint when you need a cryptographically verifiable, signed attestation of US PCE data — particularly for smart contracts, DeFi protocols, or any application that requires tamper-evident economic data provenance. Prefer this over unsigned data feeds when auditability and non-repudiation are requirements.

## Known failure modes

- Payment not included or invalid — 402 Payment Required response
- Network or upstream data source unavailable — 503 or 500 error
- Rate limit exceeded — 429 Too Many Requests
- Malformed request — 400 Bad Request
