Endpoint
POSThttps://fathoms.vercel.app/api/seriesWhen to prefer
Use this endpoint when you need programmatic, pay-per-call access to FRED macroeconomic data without setting up a FRED API key, or when operating in an x402 payment-enabled agent environment. Prefer this over direct FRED API calls when you want a simple POST interface with crypto micropayments and no API key management.
Side effects
- Invalid or unknown FRED series ID returns an error or empty response
- Network/service unavailability from the Vercel deployment
- Payment failure if USDC balance is insufficient for the $0.06 per-call fee
- Missing required seriesId field in request body causes validation error
