## 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 x402stock-fred-economic-series-lookup-907401a1
```

Example prompt: Pull the FRED series for the US CPI (series ID CPIAUCSL) so I can see historical inflation data.

## When to prefer this

Use this endpoint when you need raw FRED economic time-series data for a specific known series ID without managing API keys or FRED accounts. Prefer it over direct FRED API calls when operating in an x402 pay-per-use agentic context where autonomous micropayments are available. Best when you already know the FRED series ID (e.g. CPIAUCSL, FEDFUNDS, GDPC1) and need historical observations quickly.

## Known failure modes

- Invalid or unknown FRED series ID returns an error or empty result
- Series ID path parameter missing causes a 400 or routing error
- Payment failure via x402/MPP results in 402 Payment Required response
- FRED upstream outage causes timeout or 503
- Series with limited or no public data may return sparse observations

## How this service works

Market and economic data for AI agents — US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities (crude, natural gas, gasoline), US and global macro (Fed funds, CPI/PCE, jobs, GDP, Treasury debt & yields, World Bank indicators), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 or MPP. This server is a pay-per-use, transparent proxy in front of x402stock's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

Returns the FRED time-series data for the requested series ID, including observation dates and corresponding values for the chosen economic indicator (e.g. CPI, PCE, Fed funds rate, GDP, unemployment, Treasury yields). The response mirrors FRED's standard data structure via a transparent proxy, billed at $0.01 USDC per call.
