    https://graphadvocate.com/.well-known/agent.json ALSO answers 200 (24,298 bytes) with the same card plus a
    `_deprecation` object ({message: "This discovery path is deprecated. Use /.well-known/agent-card.json.",
    successor: <canonical URL>}). Saved verbatim as graphadvocate-com-legacy-agent.json. The provider is running
    both discovery paths through a migration and says so in-band — a rare, well-behaved pattern.

    capabilities.extensions[] carries one declared extension, uri https://x402.org/ext/a2a-payments/v1
    (required: false), whose params name the settlement network (eip155:8453), the USDC asset, the payTo address,
    the X-PAYMENT header, the httpEndpoint (https://graphadvocate.com/route) and the bazaarDiscovery URL
    (https://graphadvocate.com/.well-known/x402). Streaming, pushNotifications and stateTransitionHistory are all
    false. No securitySchemes/security block — the card documents payment, not authentication, which matches the
    provider's stated model (no API keys; wallet identity via message metadata).

    A second, smaller card (1,299 bytes) generated by the Mintlify docs host (metadata mintlify-proj: graphadvocate).
    It names the docs site as the agent url, declares one skill (graphadvocate) that points at the docs host's
    /.well-known/agent-skills/graphadvocate/skill.md, and uses supportedInterfaces[]. It is real and provider-served
    but it is a documentation-platform artifact, not the operating agent's card; the primary-host card above is
    the one agents should resolve. /.well-known/agent.json on the docs host is 404.
