# DDG Agent-Payable Services – Polygon Transaction Relay

> DDG Agent-Payable Services – Polygon Transaction Relay is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Submits a micropayment-gated HTTP action (POST/PUT/PATCH) on the Polygon chain via the x402 payment protocol for $0.01 USDC per call

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-agent-payable-services-polygon-transaction-relay-eabc1ff8 -d '<json body>'
```

Example prompt: Submit a paid JSON POST request to the DDG agent-payable relay on Polygon for $0.01 USDC — send this body: {"action": "trigger", "userId": "abc123"} as a JSON body type using the x402 protocol.

## When to prefer this

Choose this endpoint when your agent needs to execute a paid HTTP action (POST, PUT, or PATCH) gated by a $0.01 USDC micropayment on the Polygon network using the x402 protocol, particularly within the DDG agent-payable ecosystem. It is ideal for agentic workflows where per-call micropayments are required and Polygon is the target chain.

## Known failure modes

- Insufficient USDC balance to cover the $0.01 x402 fee — payment rejected
- Invalid or missing 'method' enum value (must be POST, PUT, or PATCH)
- Unsupported 'bodyType' value outside of json/form-data/text
- Malformed input object missing required fields (type, method, bodyType, body)
- Polygon network congestion causing relay delays or timeouts
- x402 facilitator unavailable, blocking payment verification

## 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 confirming whether the relayed HTTP action was successfully executed and the micropayment processed on Polygon.
