Endpoint
POSThttps://fathoms.vercel.app/api/snapshotWhen to prefer
Choose this endpoint when you need programmatic access to FRED macroeconomic time series data (GDP, CPI, unemployment, interest rates) without managing a FRED API key yourself, and when you want a pay-per-call model via x402 rather than a subscription. It is particularly useful for AI agents that need economic data on demand without pre-provisioning credentials, and for workflows that need broad coverage across FRED's 816,000+ series.
Side effects
- Invalid or unrecognized FRED series ID returns an error or empty result
- Payment of 0.2 USDC not fulfilled causes 402 Payment Required response
- Network timeout or Vercel cold-start latency causing delayed response
- Request body missing required series or parameters returns 400 Bad Request
- FRED upstream outage causing data unavailability
