```

Example prompt: Can you look up the US export control details for ECCN 5A002 — I need to know the control reasons and whether a license is required for export?

## When to prefer this

Use this endpoint when you need to quickly resolve the meaning, control reasons, and licensing requirements of a specific ECCN code in a compliance workflow. Ideal for trade compliance automation, product classification review, or pre-export screening pipelines where you have a known ECCN and need structured regulatory detail without querying the full BIS database manually.

## Known failure modes

- Invalid or malformed ECCN code returns an error or empty result
- ECCN code not found in the database returns a not-found response
- Missing required 'eccn' query parameter returns a 400 bad request
- Service unavailable returns a 5xx error
- Payment not completed returns a 402 Payment Required

## How this service works

Check US export-control status for a destination country and product: ECCN/EAR99 classification signal, license-required vs NLR, and dual-use screening against the Commerce Control List. Built for export-compliance gating in trade, procurement, and agentic workflows. Pay per check in USDC on Base, no API key, instant JSON.

## Output

Returns structured information about the specified ECCN code, including its classification description, control reasons, applicable licensing requirements, and any relevant regulatory notes under the US Export Administration Regulations (EAR).
