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
Returns a JSON object with a success indicator (ok: true) and the key data associated with the queried mail address or identifier, including any cryptographic key material or metadata stored in the DDG registry.
Example use cases
Secure mail encryption key lookup
“Find the public encryption keys for 'bob@company.org' so I can send them an encrypted message.”
Verify mail sender identity
“Look up the keys registered to 'sender@domain.com' so I can verify whether an incoming mail was legitimately signed by them.”
Bulk key resolution for contact list
“I need to retrieve the mail keys for 'contact@partner.io' — can you query the DDG key lookup service and give me the result?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/mail/keys/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve cryptographic key records specifically from the Daedalus Development Group (DDG) mail key registry, particularly in agentic workflows that already support x402 micropayment rails. Prefer this when integrating with DDG's broader agent-payable service ecosystem.
Side effects
- Key not found for the given mail address — returns error or empty result
- Invalid request body format — missing required fields like type, method, or bodyType
- Payment failure via x402 protocol — endpoint returns 402 if USDC payment is not settled
- Malformed JSON body — bodyType mismatch causes rejection
- Network timeout or service unavailability from DDG infrastructure
