## 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-deployer-x402-deployer-workers-dev-e3bf8060 -d '<json body>'
```

Example prompt: Score my resume against this job description and tell me the overall fit out of 100, plus subscores for keyword match, experience, skills, formatting, and impact — and give me the top things I should fix: [resume text] vs [job description text].

## When to prefer this

Choose this endpoint when you need a structured, multi-dimensional ATS-style fit score comparing a specific resume to a specific job description, especially when ranked improvement suggestions are needed. Prefer over generic text similarity tools when you want recruiter-calibrated subscores (keyword, experience, skills, formatting, impact) rather than a single similarity metric.

## Known failure modes

- Missing resume or job description text returns a 400 bad request
- Extremely short or malformed input may produce low-confidence scores
- Payment failure returns 402 Payment Required
- Very long documents may be truncated or time out
- Non-English resumes or job descriptions may yield lower accuracy
