## 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 bot-bazaar-spdx-license-checker-9f346eff
```

Example prompt: Can you check whether the GPL-3.0-only license allows commercial use and what copyleft obligations it imposes?

## When to prefer this

Use this endpoint when you need a quick, programmatic check on a specific SPDX license identifier (MIT, Apache-2.0, BSD-3-Clause, GPL-3.0-only, UNLICENSED) to determine commercial use eligibility and copyleft obligations, especially in automated dependency auditing or legal compliance workflows where you need structured, machine-readable answers rather than reading through full license texts.

## Known failure modes

- Unrecognized or non-SPDX license identifier returns an error or empty result
- Missing license query parameter returns a validation error
- Network or service unavailability returns a 5xx error
- Payment failure (x402) prevents access to the endpoint

## How this service works

Check an SPDX license identifier (MIT, Apache-2.0, BSD-3-Clause, GPL-3.0-only, UNLICENSED) for commercial use and copyleft obligations.

## Output

Returns the commercial use status and copyleft obligations for the given SPDX license identifier, indicating whether the license permits commercial use and what conditions (e.g. source disclosure, share-alike) apply.
