## 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 strale-license-compatibility-check-91855a74
```

Example prompt: Can you check if MIT, Apache-2.0, and GPL-3.0 are all compatible with each other — I need to know if I can legally combine these licenses in the same project?

## When to prefer this

Choose this endpoint when you need a fast, auditable license compatibility check with a verifiable cryptographic audit trail — especially valuable in regulated or enterprise environments where compliance documentation is required. Prefer this over manual legal lookup when checking combinations of multiple well-known SPDX licenses programmatically.

## Known failure modes

- Unrecognized or malformed license identifier strings may result in an error or unknown status
- Empty or missing licenses parameter returns a validation error
- Very obscure or custom licenses may not be recognized in the database
- Network timeout or upstream service unavailability returns a 5xx error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a compatibility verdict indicating whether the provided licenses can be legally combined, along with details about any conflicts or restrictions. Each response includes a cryptographic audit record with chain hashing for traceability and compliance documentation.
