# DDG PGP Sign

> DDG PGP Sign is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Signs data using PGP (Pretty Good Privacy) cryptographic signing via a machine-payable API endpoint

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/pgp/sign?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ddg-pgp-sign-dfac7fab
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pzRUnQfONwxRtmXy1m__R

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-pgp-sign-dfac7fab -d '<json body>'
```

Example prompt: Can you PGP-sign this JSON payload for me — it's a POST with JSON body {"message": "hello world"} — and give me back the signed result?

## When to prefer this

Choose this endpoint when an AI agent needs to produce PGP-signed data in a pay-per-call, machine-payable context using the x402 protocol. Ideal when integrating PGP signing into automated agentic workflows without managing a local PGP keyring. Best suited for agents that need tamper-evident signatures on JSON or text payloads and can pay micro-amounts in USDC.

## Known failure modes

- Invalid or malformed JSON body — 400 error
- Unsupported HTTP method passed in 'method' field — validation error
- Payment not provided or insufficient USDC balance — 402 Payment Required
- Body type mismatch (e.g. form-data vs json) — processing error
- Internal signing key unavailable — 500 server error

## How this service works

DDG agent-payable service request

## Output

Returns a signed output (ok: true on success) containing a PGP signature over the submitted body data, enabling downstream parties to verify authenticity and integrity of the signed payload.
