## 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-payable-arbitrum-transaction-service-00c0e104 -d '<json body>'
```

Example prompt: Submit a JSON body with my order data to DDG's Arbitrum agent-payable service using a POST request — the body should include my item ID and quantity, and pay the $0.01 USDC fee.

## When to prefer this

Choose this endpoint when your agent needs to submit a paid HTTP request to DDG's Arbitrum-based infrastructure using the x402 micropayment protocol, particularly when orchestrating on-chain or agent-payable workflows at $0.01 USDC per call. Prefer this over generic HTTP relays when you need tight integration with DDG's chain-specific agent services.

## Known failure modes

- Insufficient USDC balance for $0.01 payment — payment rejected
- Invalid HTTP method supplied (must be POST, PUT, or PATCH) — validation error
- Malformed or missing required body fields — schema validation failure
- Arbitrum network congestion or downtime — service unavailable
- Unsupported bodyType value outside json/form-data/text — enum 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

Returns a JSON object with an 'ok' boolean indicating whether the paid request was successfully processed by the DDG Arbitrum chain endpoint.
