How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
A JSON array of inflation expectation series, each with an as-of date, the rate value (e.g. 2.39%), a human-readable label (e.g. '5-Year breakeven inflation rate (TIPS)'), a measure identifier (e.g. '5y-breakeven'), and a FRED series ID (e.g. 'T5YIE'). Also includes total count and source attribution to FRED/Federal Reserve Bank of St. Louis.
Example use cases
Example prompt
“What are the latest market-based inflation expectations right now — give me the 5-year breakeven and the 5-year 5-year forward rates from the Fed's FRED data?”
Technical details
Endpoint
GEThttps://2s.io/api/inflation/expectationsWhen to prefer
Choose this endpoint when you need current, authoritative market-based inflation expectations (breakeven rates, forward rates) derived from TIPS spreads and published by the Federal Reserve. Prefer over general financial APIs when you specifically need FRED-sourced, bond-market-implied inflation data with no signup or API key required.
Side effects
- Payment not received or invalid USDC payment returns 402
- FRED upstream data unavailable returns error with ok:false
- Rate limiting or service outage returns 5xx error
- Stale data if FRED has not published recent figures
