# DDG Prediction Markets Data Service

> DDG Prediction Markets Data Service is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns bounded prediction market data artifacts via a machine-payable POST endpoint using x402 USDC micropayment rails

## Facts

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-prediction-markets-data-service-3ccb2b55 -d '<json body>'
```

Example prompt: Can you fetch the current prediction market data and probabilities from DDG's agent-payable service for the upcoming US election outcome — I'll pay the micropayment fee via USDC?

## When to prefer this

Choose this endpoint when an AI agent needs to access prediction market probabilities or outcomes on a pay-per-call basis without requiring a subscription or API key — ideal for infrequent or one-off queries where x402 USDC micropayment rails are available. Best suited for agents that operate autonomously and can handle machine-payable flows at $0.005 USDC per call.

## Known failure modes

- Payment failure or insufficient USDC balance causing 402 rejection
- Missing required 'input' or 'output' fields in the request body causing schema validation error
- Invalid method enum (must be POST, PUT, or PATCH) causing rejection
- Network timeout or provider unavailability returning non-200 response
- Invalid bodyType enum value causing request rejection
- Empty or malformed body object causing processing 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 object with an 'ok' boolean confirmation and bounded prediction market result data including probabilities, outcomes, or market state for the queried event — delivered as a finite artifact rather than raw provider account access.
