## 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 x402-factory-department-of-transportation-contract-awards-3634a1d3
```

Example prompt: Pull up the 10 most recent Department of Transportation contract awards since January 1, 2024 — filter to NAICS code 541330 and only show contracts worth at least $500,000.

## When to prefer this

Choose this endpoint when you specifically need Department of Transportation contract awards and want a pre-filtered, ready-to-use feed without constructing USAspending queries yourself. It is faster and cheaper than calling USAspending directly for DOT-scoped research. Prefer it over the generic /v1/contracts/awards endpoint when your query is DOT-specific, saving filter parameters. Use over sibling endpoints (GSA awards) when the focus is transportation infrastructure, logistics, or DOT sub-agencies.

## Known failure modes

- Invalid NAICS format (not 2–6 digits) returns a validation error
- Invalid date format for 'since' parameter returns a schema error
- limit out of range (>50 or <1) returns a validation error
- No results found for very narrow filter combinations returns an empty awards array
- Payment failure ($0.02 USDC) results in 402 response blocking data access
