## 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-sic-code-lookup-c5322d08 -d '<json body>'
```

Example prompt: What industry and government office does SIC code 7372 correspond to?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call resolution of a known SIC code to its official industry classification without setting up an API key. Ideal for enriching corporate records, validating business filings, or classifying companies by sector in automated agent workflows. Prefer this over manual lookup tables when freshness and confidence scoring matter.

## Known failure modes

- Invalid or non-existent SIC code returns supported:false or low confidence
- Malformed 4-digit input (e.g. letters, fewer than 4 digits) may return a validation error
- Obscure or deprecated SIC codes may return warnings or reduced confidence
- Payment failure via x402/USDC halts the request before processing

## How this service works

Resolves SEC Standard Industrial Classification (SIC) details and category descriptions.

## Output

Returns the resolved industry label (e.g. 'Services-Prepackaged Software'), the associated government office (e.g. 'Office of Technology'), the original SIC code echoed back, a confidence level ('high'/'medium'/'low'), a data currency date, a 'supported' boolean, any warnings, and a legal disclaimer noting results are informational only.
