# DDG Multi-Search Research Endpoint

> DDG Multi-Search Research Endpoint is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-03).

Performs a paid web search query via DDG's agent-payable service, returning bounded search results for a given query, paid per-call using x402 USDC micropayments.

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-multi-search-research-endpoint-985f7235 -d '<json body>'
```

Example prompt: Search the web for the latest developments in quantum computing and give me a summary of what you find — use DDG's agent search service to pull real results.

## When to prefer this

Choose this endpoint when an AI agent needs real-time web search results and can pay per-query via x402 USDC micropayments on-chain. Prefer this over free-tier search APIs when budget control per query matters, or when operating in an autonomous agent workflow that supports x402 payment rails. Not suitable for bulk/batch scraping or raw provider account access — DDG sells bounded results only.

## Known failure modes

- Payment not completed or x402 payment header missing — returns 402 Payment Required
- Malformed request body (missing required 'input' or 'output' fields) — returns 400 Bad Request
- Query produces no results — returns ok:true with empty results array
- Provider backend (DuckDuckGo) unavailable — returns 5xx error
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works

DDG agent-payable service request

## Output

Returns a JSON object with ok:true and a bounded set of web search results (snippets, titles, URLs) matching the submitted query, sourced from DuckDuckGo via the DDG agent-payable infrastructure. Exact result count and structure depend on the query body submitted.
