# Aayat AI License Compatibility Checker

> Aayat AI License Compatibility Checker is a paid API for AI agents from aayatai.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Checks software licence compatibility for each dependency against a project's own licence and usage model, returning ok/conditions/review/incompatible status per dependency with reasons.

## 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 aayat-ai-license-compatibility-checker-70ab22ae -d '<json body>'
```

Example prompt: Check if these dependencies are compatible with my proprietary SaaS product: GPL-3.0-only, MIT, AGPL-3.0-only, npm:express@4.21.2, and pypi:requests — usage is saas.

## When to prefer this

Choose this endpoint when an AI coding agent needs rapid, structured, per-dependency licence compatibility verdicts without manual legal research — especially during CI/CD pipelines, pre-release audits, or when evaluating new dependencies for a project with a known licence and deployment model. It is particularly useful for catching copyleft and network-copyleft conflicts (GPL, AGPL, LGPL, MPL) before they become legal liabilities.

## Known failure modes

- Unrecognized package name or version returns an error or unknown status for that dependency
- Invalid SPDX identifier causes parsing failure for that entry
- Exceeding 50 dependencies in a single request results in a validation error
- Ambiguous dual-licence packages may return a 'review' status requiring human judgment
- Edge cases in less common licences (e.g. EUPL, CDDL) may produce imprecise results

## How this service works

Licence compatibility check for coding agents: give your project's licence (or proprietary) and how it's used (distributed, SaaS or internal) plus up to 50 dependencies as SPDX ids or packages (npm:express@4.21.2); get ok / conditions / review / incompatible per dependency with the reason (GPL, AGPL, LGPL, MPL, Apache, dual licences...). Not legal advice.

## Output

A JSON response listing each dependency with its detected licence, licence family (permissive, copyleft, network-copyleft, etc.), compatibility status (ok, conditions, review, or incompatible), and a plain-language reason. Includes an overall verdict and summary string for the whole dependency set, plus a disclaimer that this is not legal advice.
