## 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 sitecheck-jobs-property-resume-ats-keyword-coverage-scorer-2f7d8f05
```

Example prompt: Can you check how well my resume matches this job description and tell me which keywords I'm missing? Here's my resume: 'Experienced data engineer with 5 years working on ETL pipelines, Python, and AWS...' And here's the job ad: 'We are looking for a Data Engineer skilled in Spark, Kafka, Airflow, and AWS...' Show me the coverage score and the top 20 terms to focus on.

## When to prefer this

Choose this endpoint when you need a fast, deterministic ATS-style keyword gap analysis between a resume and a job ad without AI rewriting or data storage. Ideal for agents helping users tailor resumes before applying, or for recruiters doing lightweight candidate screening. Prefer this over AI-based resume rewriters when the user wants transparency about which exact terms are missing and a reproducible numeric score, rather than a rewritten document.

## Known failure modes

- Missing 'resume' or 'job' query parameters returns an error
- Resume or job text exceeding character limits (6,000 / 4,000 chars) may be truncated or rejected
- Very short or generic job ads may yield few extractable terms and a low-signal score
- Non-English text may produce poor keyword extraction results
- Score reflects keyword coverage only — not experience relevance, truthfulness, or semantic similarity

## How this service works

Resume vs job-ad keyword check, the way applicant tracking systems screen: extracts the job ad's key terms (words and two-word phrases, weighted by frequency), shows which the resume already covers and which are missing, and gives a 0-100 coverage score and the top terms to add. Plain text analysis of the two texts you send; no AI rewriting and no data is stored.

## Output

Returns a JSON object with a 0–100 integer coverage score, an array of covered terms each with a frequency weight, an array of missing terms each with a frequency weight (sorted by importance), and a suggestions array with plain-English recommendations for which terms to add to the resume if applicable.
