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

Returns a JSON object confirming the watcher was registered, including the watcher record(s) in an items array, a total count, an ok:true flag, and source attribution (provider, URL, license). Once active, the watcher POSTs a signed callback event to the specified URL each time the FRED series breaches the threshold, including an X-2s-Signature header for verification and the optional echo payload.

Example use cases

Treasury yield breach alert for bond desk

“Watch the DGS10 FRED series and POST to https://alerts.mybonddesk.com/webhook when the 10-year yield goes above 4.75% — let it fire up to 5 times over the next 90 days and tag it 'bond-desk-q3'.”

Unemployment rate dip trigger for hiring model

“Monitor the UNRATE FRED series and call back https://hr.myplatform.io/trigger when unemployment falls below 4.0% — fire just once and expire after 30 days.”

Fed funds rate cut detector for trading bot

“Set up a watcher on FEDFUNDS that sends a POST to https://trading.mybot.io/fed-event whenever the federal funds rate drops below 5.0%, with a max of 10 fires and active for 60 days.”

When to prefer

Use this endpoint when you need event-driven, webhook-based alerts on FRED macroeconomic series (Treasury yields, unemployment, CPI, fed funds rate, etc.) rather than polling for data yourself. It is ideal for trading systems, economic dashboards, hiring models, or any automated pipeline that must react to a specific economic threshold being crossed. Prefer this over polling the FRED data endpoints directly when you want push-based notification with signature verification, configurable fire limits, and built-in expiry — without managing a cron job or scheduler yourself.

Side effects

Invalid FRED series ID returns an error or empty result
Callback URL unreachable causes silent callback failure (no retry guarantee)
Threshold never crossed within expiry window — watcher expires without firing
maxFires exceeded — watcher self-deactivates after limit is reached
expiresInSeconds out of range (< 60 or > 7776000) causes validation error
Malformed conditionType enum value causes request rejection
Missing required fields (seriesId, threshold, conditionType, callbackUrl) returns 400
Payment failure via x402 prevents watcher creation
