## 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 tenderwatch-procurement-search-fit-score-f6e67edf
```

Example prompt: Pull up the SAM.gov opportunity with ID SPMYM222R0042 using TenderWatch and tell me how good a fit it is for us.

## When to prefer this

Use this endpoint when you have a specific procurement opportunity ID and need both the full structured details and a heuristic fit score in a single call. Prefer this over generic web scraping or direct SAM.gov/TED API calls when you want built-in fit scoring for BD prioritization. Ideal for AI-driven sales agents that need to triage opportunities one-by-one against a company profile.

## Known failure modes

- 402 Payment Required — call not preceded by valid x402 USDC payment
- 404 Not Found — opportunity ID does not exist in the specified source
- 400 Bad Request — missing or invalid 'source' query parameter (must be 'sam' or 'ted')
- 503 Service Unavailable — upstream SAM.gov or TED API is unreachable
- Stale data — opportunity may have closed or been amended since last index

## How this service works

Per-call government procurement search (EU TED + US SAM.gov) and heuristic fit-scoring for BD/sales agents. Priced routes return 402 until paid via x402. Terms of service: GET /terms (free).

## Output

Returns the full details of a specific government procurement opportunity (title, description, deadline, contracting authority, value, etc.) along with a heuristic fit score indicating how well the opportunity matches a typical BD/sales profile. Source is either SAM.gov (US federal) or TED (EU).
