Example prompt: Can you pull the upcoming US macro event calendar for the next 30 days — I need the signed oracle data so I can use it in a smart contract or trading system?

## When to prefer this

Choose this endpoint when you need a cryptographically attested, oracle-ready US economic event calendar for use in smart contracts, DeFi protocols, or any application requiring verifiable macro data provenance. Prefer over generic calendar APIs when Ed25519 attestation and on-chain verifiability are required.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required
- Service temporarily unavailable — 503 or timeout
- Invalid or expired signature on response — client-side verification failure
