# DDG Mail Keys Lookup

> DDG Mail Keys Lookup is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Looks up cryptographic keys associated with mail addresses via a paid HTTP POST endpoint

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/mail/keys/lookup?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ddg-mail-keys-lookup-46f01153
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3b1EqccEoktOK9JTulpKz

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ddg-mail-keys-lookup-46f01153 -d '<json body>'
```

Example prompt: Can you look up the cryptographic keys associated with the mail address 'alice@example.com' using the DDG mail key lookup service?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
