# License Intel – SPDX License Lookup

> License Intel – SPDX License Lookup is a paid API for AI agents from license-intel.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Returns full metadata for a given SPDX license ID: official name, OSI/FSF status, deprecation flag, reference links, and plain-language permissions, conditions, and limitations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 license-intel-spdx-license-lookup-6552e12c
```

Example prompt: Can you look up the Apache-2.0 license and tell me its official name, whether it's OSI-approved and FSF-libre, if it's deprecated, and what its plain-language permissions and conditions are?

## When to prefer this

Use this endpoint when you need rich, structured metadata for a single known SPDX license ID — including OSI/FSF status, deprecation state, plain-language permissions and duties, and reference links. Prefer it over the search endpoint when you already know the exact SPDX identifier. For comparing two licenses, use the comparison endpoint; for classifying multiple licenses by strength, use the classify endpoint.

## Known failure modes

- Unknown SPDX ID returns null or empty fields with a degraded flag
- Deprecated license IDs may return data but with deprecated=true and a note suggesting modern alternatives
- Malformed or missing 'id' query parameter results in a 400-level error
- Service unavailability causes a payment-accepted but empty/error response

## How this service works

Look up an SPDX license id: name, OSI and FSF status, deprecated flag, links, and plain-language permissions and duties.

## Output

Returns a structured object containing the license's official name, SPDX ID, OSI-approved and FSF-libre boolean flags, deprecated flag, reference URL, seeAlso links, license family, plain-language permissions, conditions, limitations, a summary, overview, verdict, and metadata such as list version and data freshness timestamp.
