How this service works
Search Stack Overflow questions (keyless). Each result: title, link, score, answer count, answered flag, view count, tags, creation date, and question id. Sort by relevance, votes, activity, or creation. For coding agents that need authoritative Q&A on errors, APIs, and language features.
Output
A list of up to 30 Stack Overflow questions, each containing: title, direct link, community score, answer count, answered flag, view count, associated tags, creation date, and question ID — ready for an agent to surface relevant threads or drill into specific answers.
Example use cases
Example prompt
“Search Stack Overflow for the top 10 questions about async await deadlock in C#, sorted by votes, and show me the titles, scores, and whether they've been answered.”
Technical details
Endpoint
GEThttps://2s.io/api/dev/stackoverflow-searchWhen to prefer
Use this endpoint when a coding agent needs to surface authoritative, community-vetted Q&A from Stack Overflow — especially for error messages, API usage questions, or language-specific patterns. Prefer this over general web search when the query is programming-specific and you want structured metadata (score, answer count, tags) rather than raw HTML. It requires no API key and charges only per call.
Side effects
- Empty results if the query is too obscure or misspelled
- Rate limiting or quota exhaustion returning an error
- Query string too short (under 2 characters) or too long (over 200 characters) causing validation failure
- Network timeout if Stack Overflow upstream is slow
- Payment failure via x402 protocol if USDC balance is insufficient
