# AP2

AP2 carries payment mandates over the A2A protocol, declaring which roles an agent plays in a transaction.

## When to use this skill

Use this when a site fails the "AP2" check and you need to implement it.

## Goal

Advertise Agent Payments Protocol support through your A2A Agent Card

## Pass criteria

The A2A Agent Card advertises an AP2 extension with role information.

## Implementation

This skill covers the diagnosis. The step-by-step implementation prompt is part
of the paid tier and is served per scan by the API — see https://agent-ready.t0ols.com/llms-full.txt.

## Specifications

- https://ap2-protocol.org/
- https://a2a-protocol.org/

## Verifying

Re-run the scan against the site and confirm the check reports a pass:

    curl -s https://agent-ready.t0ols.com/api/scan \
      -H 'content-type: application/json' \
      -d '{"url":"https://example.com","enabledChecks":["ap2"]}'
