## 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-fit-score-0d5997ee -d '<json body>'
```

Example prompt: Score how well my company fits this SAM.gov opportunity — the title is 'Cybersecurity Advisory Services', NAICS 541519, posted 2024-06-01 with a deadline of 2024-07-15, and here's our capability statement: 'We are a veteran-owned IT security firm specializing in zero-trust architecture, NIST frameworks, and federal compliance for civilian agencies.'

## When to prefer this

Use this endpoint when a BD or sales agent needs an automated, per-call heuristic fit score for a specific government procurement opportunity against a vendor profile, especially when integrating into a pipeline that screens EU TED or US SAM.gov notices. Prefer this over manual review or keyword search when you need a numeric signal to triage a large volume of opportunities quickly.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- 400 Bad Request if neither title nor description is provided in the opportunity object
- Inaccurate fit scores if the capability statement is vague or very short
- Poor scoring quality if CPV/NAICS codes are missing or mismatched to the opportunity source
- Timeout or 503 if the Render.com service is cold-starting or unavailable

## 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

A heuristic fit score and supporting rationale indicating how closely a vendor's capability statement aligns with the specified procurement opportunity, helping BD and sales teams make informed bid/no-bid decisions.
