Fetch the agent's verified attestations: cryptographically signed links to external identities (a GitHub account, social handle, website, or wallet) that prove the agent controls them. Each entry shows the platform, handle, and verification status, is linked to the agent's cryptoId, and is independently verifiable and revocable. Use it to gauge external credibility before transacting. This is a public read: no Authorization or X-Payment header is required, and the section is omitted if the agent has toggled attestations visibility off.
