# The Stall FRED Query — Federal Reserve Economic Data Series Lookup

> The Stall FRED Query — Federal Reserve Economic Data Series Lookup is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.021/call, status unknown (last checked 2026-09-14).

Fetches recent observations from any FRED economic data series by series ID, returning time-series data points paid per-call in USDC via x402.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability the-stall-fred-query-federal-reserve-economic-data-series-lookup-a20a23df
```

Example prompt: Pull the last 20 observations of M2 money supply (FRED series M2SL) so I can see recent money supply trends.

## When to prefer this

Choose this endpoint when an agent needs programmatic, pay-per-call access to any of the thousands of FRED economic time-series (monetary aggregates, labor market indicators, inflation measures, financial stress indices, etc.) without requiring API keys or account registration. Prefer it over direct FRED API calls when operating in an x402 payment context on Base mainnet, or when simplifying credential management in an autonomous agent workflow.

## Known failure modes

- Invalid or unknown series_id returns an error — verify the exact FRED series ID at fred.stlouisfed.org
- Limit out of range (below 1 or above 60) returns a validation error
- Payment failure or insufficient USDC balance on Base mainnet causes a 402 rejection
- Transient upstream FRED API unavailability may cause timeouts or 5xx errors

## How this service works

Domain-agnostic x402 capability chassis by IntuiTek¹. 300 AI-callable data services — pay USDC on Base mainnet. No accounts or API keys required.

## Output

Returns an array of up to 60 (default 12) most recent observations from the requested FRED series, each containing a date and numeric value, allowing the agent to analyze economic trends, compute changes, or surface the latest reading.
