## 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-license-obligations-checklist-4635a686
```

Example prompt: Can you pull up the full obligations checklist for the Apache-2.0 license — what it lets me do, what I have to do when I distribute, and what's disclaimed?

## When to prefer this

Use this endpoint when you need a structured, human-readable obligations checklist for a specific SPDX license — covering permissions, distribution conditions, and disclaimers in plain language. Prefer this over the raw SPDX lookup endpoint when you need pre-parsed, plain-English summaries rather than raw SPDX metadata. Use the compare endpoint instead if you need to contrast two licenses side by side.

## Known failure modes

- Unknown or invalid SPDX id returns null fields or an error response
- Deprecated SPDX ids may return limited or missing data
- Network timeout may occur under high load
- Degraded flag set to true if some obligation fields could not be retrieved
- Malformed query parameter (missing id) results in a 400-level error

## How this service works

Plain-language checklist for a license: what you may do, what you must do when you distribute, and what is disclaimed.

## Output

A structured plain-language breakdown including: the license id, title, family, and family note; a summary and verdict; a list of permissions (what you may do), conditions/obligations (what you must do when distributing), and limitations/disclaimers; attribution and distribution requirements; a degraded flag if data is incomplete; a list of unchecked items; and a source/timestamp.
