## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.005 USDC), pay-per-call web search using DuckDuckGo Instant Answers — ideal for factual lookups, quick research, or agent workflows where low latency and per-query micropayment billing (via x402) are preferred over subscription-based search APIs.

## Known failure modes

- Empty results array if DuckDuckGo has no instant answer for the query
- Query too long (exceeds 400 characters) returns validation error
- No internet connectivity or upstream DuckDuckGo outage returns error status
- Malformed JSON body or missing required 'query' field causes 4xx error
- Payment failure via x402 protocol blocks request before processing
