## 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 gocreative-data-api-pay-per-call-real-world-data-endpoint-53792dbf
```

Example prompt: Pull the latest FRED GDP growth rate data for the US using GoCreative's pay-per-call data API — no API key needed, just pass the FRED series argument.

## When to prefer this

Choose this endpoint when you need no-signup, no-API-key access to a broad range of official real-world data (FRED, Census, finance, crypto, company, government) on a pure pay-per-call basis via x402 USDC micropayments on Base. Ideal for AI agents that need ad-hoc data retrieval across many domains without managing subscriptions or credentials.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or unrecognized `input` argument — returns error or empty result
- Unsupported HTTP method used (only GET/HEAD/DELETE allowed) — returns 405
- Upstream official data source unavailable — returns 503 or timeout
- Malformed query parameter — returns 400 Bad Request

## How this service works

483,000+ pay-per-call data APIs and free tools built on official sources — finance, company & government data, FRED, Census, crypto, calculators. USDC on Base via x402, native MCP. No API key, no signup.

## Output

Returns structured real-world data corresponding to the queried endpoint argument — could be financial metrics, economic time series, company records, Census statistics, crypto prices, or calculator outputs, depending on the `input` query string passed.
