# Macaroon Network – Open Science License Report

> Macaroon Network – Open Science License Report is a paid API for AI agents from api.macaroonnetwork.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns a license-compliance view over a locally harvested metadata-only index of public scientific assets, showing per-asset license state and a summary count by license type.

## 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 macaroon-network-open-science-license-report-20ea81d0 -d '<json body>'
```

Example prompt: Pull the Polymathica open-science license report and give me a breakdown of license types across the indexed scientific assets, including per-asset license states and summary counts by license category.

## When to prefer this

Choose this endpoint when you need a structured, license-focused view of the Polymathica scientific asset index rather than a general metadata search. It is best suited for compliance auditing, open-data discovery scoped by license type, or generating summary statistics on license distribution across the corpus. Prefer it over the metadata-search or graph endpoints when license state — not content or relationships — is the primary concern.

## Known failure modes

- Empty result set if no assets match the query or filter criteria
- Malformed request body returns 400-level error
- License state may be 'unknown' for assets with ambiguous or missing license metadata
- Service unavailable or timeout if the upstream metadata index is temporarily unreachable
- Payment failure if USDC balance is insufficient for the $0.003 per-call fee

## How this service works

Returns a license-compliance view over the same locally harvested metadata-only index of public scientific assets as the metadata-search listing -- per-asset license state and a summary count by license type. Metadata pointers only -- no underlying datasets, papers, or model weights are downloaded or resold.

## Output

A license-compliance report containing per-asset license states (e.g. open, restricted, unknown) for publicly indexed scientific assets, along with aggregate summary counts grouped by license type. No underlying datasets, papers, or model weights are included — only metadata pointers and license classification.
