## 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 datakoot-federal-register-agencies-lookup-2f5cd62b -d '<json body>'
```

Example prompt: Search the Federal Register for any agencies whose name contains 'Energy' and give me their IDs and short names.

## When to prefer this

Use this endpoint when you need to resolve a US Federal Register agency name to its canonical ID, slug, or short name — especially when preparing to query Federal Register rules, notices, or documents by agency. Prefer this over manual lookup or web scraping when you need structured, machine-readable agency identifiers at low cost ($0.002 USDC per call). Also available free via MCP for up to 100 calls/day.

## Known failure modes

- No agencies match the query string — returns empty list with count 0
- Payment failure via x402 — call is not charged if unsuccessful
- Malformed query parameter — API may return 400 error
- Service unavailable — upstream Federal Register data temporarily inaccessible

## How this service works
