## 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-agent-marketplace-listing-pack-8e20fa7f -d '<json body>'
```

Example prompt: Can you fetch me the DDG agent marketplace listing pack — I want to see what machine-payable services Daedalus Development Group offers, and I'm happy to pay the $0.02 USDC via x402.

## When to prefer this

Choose this endpoint when an AI agent needs to discover or retrieve the full catalog of DDG machine-payable services and is equipped to settle a $0.02 USDC micropayment via the x402 protocol. Prefer this over generic service directories when you specifically want DDG's bounded artifact offerings and need a crypto-native payment rail (multi-chain USDC). Not suitable if you need raw provider account access or if your agent cannot handle x402 payment challenges.

## Known failure modes

- Payment not settled — x402 payment rail fails or USDC not confirmed, returning 402 Payment Required
- Invalid request body — missing required fields (type, method, bodyType, body) returns 400 Bad Request
- Unsupported HTTP method in body — only POST/PUT/PATCH allowed in inner method enum
- Provider environment not live — MPP/Stripe/Tempo pending, so only x402 and direct-crypto rails are active
- Network timeout or upstream service unavailability returns 5xx error

## 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 containing a marketplace listing pack artifact (ok: true on success) describing the bounded services and results DDG sells to AI agents, delivered after a successful $0.02 USDC x402 micropayment settlement.
