## 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-search-01a24223
```

Example prompt: Search the SPDX license list for anything matching 'creative commons' and show me up to 10 results — only OSI-approved ones, no deprecated IDs.

## When to prefer this

Use this endpoint when you need to discover or enumerate SPDX licenses by a partial name or ID string, especially when filtering for OSI-approved licenses. Prefer this over the full-list endpoint when you have a keyword and want ranked/filtered matches rather than the complete catalog.

## Known failure modes

- Query too short (under 2 chars) or too long (over 40 chars) returns a validation error
- No licenses match the fragment — returns empty results array with totalMatches 0
- osiOnly or includeDeprecated values other than 'yes' may be ignored or cause errors
- SPDX upstream unavailable — may return degraded=true with partial or no results
- limit outside 1–50 range may be rejected or clamped

## How this service works

Search the SPDX license list by name or id fragment, such as gpl or creative commons, with OSI and deprecated flags.

## Output

Returns a list of matching SPDX license records (up to the requested limit), each with the license name, SPDX ID, OSI-approved flag, FSF-libre flag, and deprecated flag, plus total match count, the SPDX list version used, source URL, and summary/verdict text.
