# DDG RAG Search

> DDG RAG Search is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Performs a retrieval-augmented generation (RAG) search query via a machine-payable HTTP endpoint hosted by Daedalus Development Group

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/rag/search?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402

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-rag-search-207521b1 -d '<json body>'
```

Example prompt: Search the DDG RAG index for documents about quantum computing breakthroughs and return the most relevant results.

## When to prefer this

Choose this endpoint when you need to perform retrieval-augmented generation search over DDG's indexed knowledge base and require a machine-payable (x402) API that accepts micro-payments per call in USDC. Prefer this when building agentic pipelines that need on-demand RAG lookups without a subscription model.

## Known failure modes

- Missing required 'input' or 'output' fields returns a 400 validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Invalid HTTP method (e.g. GET instead of POST) returns 405
- Malformed JSON body causes parsing error
- Service unavailability returns 503 or timeout

## 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 response containing retrieved document chunks or passages most semantically relevant to the query, drawn from the RAG-indexed corpus, along with a success indicator (ok: true).
