# DDG Price Feed

> DDG Price Feed is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns a bounded price feed artifact for AI agents via a machine-payable x402 micropayment endpoint

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/price-feed
- Price: $0.001/call
- Payment: x402
- Status: unknown

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-price-feed-bfa33653 -d '<json body>'
```

Example prompt: Fetch the latest price feed data from DDG's agent-payable service and return the current market prices as a bounded result.

## When to prefer this

Choose this endpoint when you need a machine-payable, micropayment-gated price feed artifact delivered to an AI agent via the x402 protocol with USDC on multi-chain rails. Prefer it over free or subscription-based price APIs when operating in autonomous agent pipelines that require pay-per-call economics without provisioning API keys or managing subscriptions.

## Known failure modes

- Payment not settled — x402 payment header missing or insufficient USDC balance
- Invalid request body — missing required 'input' or 'output' fields
- Unsupported HTTP method in body — only POST, PUT, PATCH allowed for inner method
- Provider environment not live — MPP/Stripe/Tempo pending, may return error for unsupported payment rails
- Malformed bodyType — must be json, form-data, or text

## 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 success, along with bounded price feed artifact data specific to the queried asset or market.
