## 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 usaspending-federal-agencies-lookup-f66c415a -d '<json body>'
```

Example prompt: Give me the full list of all US federal top-tier agencies from USAspending.gov, including their names, abbreviations, toptier codes, and current-year budget authority so I can look up the right agency code for a federal spending query.

## When to prefer this

Choose this endpoint when you need a complete, authoritative list of US federal top-tier agency codes and metadata for use with USAspending.gov queries, especially when you need to resolve a human-readable agency name to its toptier code. Preferred over manually maintaining a static agency list since it reflects current-year budget authority. Keyless and pay-per-call via x402 makes it suitable for on-demand lookups without API key management.

## Known failure modes

- Payment failure or missing x402 payment header results in 402 response
- USAspending.gov upstream unavailable may cause timeout or 503
- Empty or malformed POST body may cause 400 error if schema validation is strict
- Rate limiting if too many calls are made in rapid succession
