## 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 bizintel-api-job-taxonomy-lookup-ef435af5 -d '<json body>'
```

Example prompt: What is the official O*NET occupational code and standardized title for the job title 'Machine Learning Engineer'?

## When to prefer this

Use this endpoint when you need to map free-text job titles to official O*NET occupational codes for workforce analytics, HR systems, compliance reporting, labor market research, or resume parsing pipelines. Prefer it over generic LLM-based classification when you need a verifiable, citable O*NET code with a confidence signal rather than an approximate categorization.

## Known failure modes

- Ambiguous or highly niche job title may return lower confidence score or unsupported flag
- Very informal or slang role names may not map cleanly to a taxonomy entry
- Outdated O*NET version if data_as_of lags behind the latest SOC revision
- No match found returns supported:false with empty or null onet_code
- Payment failure via x402/USDC on Base prevents the call from executing

## How this service works

Resolves job titles to O*NET standard codes and role descriptions.

## Output

Returns a JSON object with the standardized O*NET occupational title (e.g. 'Software Developers'), the O*NET code (e.g. '15-1252.00'), a confidence level (high/medium/low), a supported boolean indicating whether the taxonomy lookup succeeded, a data_as_of date for the reference data vintage, any warnings, and a disclaimer about informational use only.
