Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/research/search-multi?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
