How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
A JSON response confirming the operation result with an 'ok' boolean, plus details about the key binding record — including the agent identity, the SHA-256 fingerprint of the ed25519 key, the binding action performed, and the updated trust/verification status.
Example use cases
Onboarding a new agent signing key
“I need to bind my agent's new ed25519 public key to its DDG identity — the fingerprint is sha256:7f3a9b2c1e4d... — so it shows up as fully verified rather than just trusted on first use.”
Revoking a compromised agent key
“My agent's old signing key was exposed — please revoke the key binding with fingerprint sha256:deadbeef1234... from my DDG agent identity right away so it can no longer be used.”
Resolving current key for an agent identity
“Can you look up and return the currently pinned ed25519 signer key binding for agent identity 'agent-id-99f2b7' on DDG so I can confirm which key is active?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/tine/key-bind?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically anchor an agent identity to a specific ed25519 signing key within the DDG trust framework — especially when you want to upgrade agent trust level from verified-tofu (first-use heuristic) to fully verified (explicit key pinning). Prefer this over generic PKI or DID systems when operating within the DDG agent-payable services ecosystem and x402 payment rails.
Side effects
- Invalid or malformed ed25519 key fingerprint returns a validation error
- Attempting to revoke a non-existent binding returns a not-found error
- Payment failure via x402 protocol results in 402 response and no state change
- Conflicting key binding (already registered) may return a conflict error
- Unauthorized agent identity access returns 401/403
- Malformed JSON body returns 400 bad request
