## 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 srch-best-spending-data-2d6bbfbd -d '<json body>'
```

Example prompt: Find me up to 20 federal contracts and grants awarded to Lockheed Martin between January 1 2023 and December 31 2023 with a minimum award amount of $1,000,000.

## When to prefer this

Choose this endpoint when you need structured, queryable U.S. government spending data — especially contracts and grants — with filtering by agency, recipient, amount, date range, and award type. Prefer it over generic web search when you need clean, machine-readable award records rather than unstructured HTML pages. It is especially useful for competitive intelligence on government contractors, agency budget analysis, or compliance research requiring precise fiscal data.

## Known failure modes

- Query too short (under 2 characters) returns validation error
- Date format not ISO 8601 YYYY-MM-DD causes rejection
- Limit above 100 or below 1 returns validation error
- Invalid award type enum value causes schema validation failure
- Payment failure via x402 protocol returns 402 Payment Required
- No matching records returns empty result set
- Cursor from a different query or expired cursor returns error or empty page
