Use cases

An assessment is always bound to an intended use; each use case maps to a distinct right in the license library.

• Commercial use of licensed digital assets — May an agent acquire and commercially exploit this asset? a2ally checks the controlling terms' reviewed profile for the commercial_use permission and any prohibition before any purchase.
• Using assets for AI model training — Training use is a distinct right from inference. a2ally assesses model_training separately: prohibited training returns BLOCK, undocumented training INSUFFICIENT_EVIDENCE, and training under licenses whose conditions may or may not reach a trained model HUMAN_REVIEW. Permission is never assumed.
• Using assets at inference time — Runtime/inference use (retrieval, display, generation context) assessed against the reviewed profile independently of training rights.
• Redistributing licensed assets — Passing the asset (or copies) to third parties requires an explicit documented redistribution permission in the controlling terms.
• Modifying and creating derivatives — Modification/derivative-work rights are checked against the reviewed profile; duties such as attribution are surfaced as required next actions.
• Sublicensing rights to others — Granting others rights under the license. Creative Commons and GNU licenses do not allow it; MIT and Apache 2.0 do. a2ally returns BLOCK where the license prohibits it.
• Deploying assets in production systems — Using an asset in a live product or service. Assessed against the license's grant and duties; deploying adapted material counts as sharing it, which NoDerivatives licenses do not allow.
• Attribution duties — Where a profile carries an attribution duty, assessments flag attribution planning as a required next action before use.

For agents

This directory as data: GET /v1/discover, and one category at GET /v1/discover/<category>. Verification stays free and needs no key. Fees, where any apply, are on the pricing page.

Counters are live-computed from the registry on every read: resources are the public, active resources in the registry at the moment of the read, and every count and list in this document is derived from them at that moment. Nothing is cached or stored. Markdown twin: /discover.md.
