How this service works
Web search that returns raw results plus an AI-synthesised, properly cited Markdown report. Pay per call in USDC over x402. No API key, no account.
Output
A JSON object containing: the AI-generated Markdown report with inline citation numbers, a structured citations array (number, URL, quote, title), a list of pages read with word counts, usage stats (elapsed ms, pages read, web searches performed, token counts), a completion summary (turns, LLM calls, stop reason), and a list of open questions the research could not fully resolve.
Example use cases
Competitive landscape research brief
“Research the current competitive landscape for vector database providers in 2025 and give me a cited Markdown report covering the top players, their pricing, and where the market is heading.”
Technical due diligence on a new standard
“I need a thorough, citation-backed report on the current state of the EU AI Act — what's actually in force, what's coming, and what companies need to do to comply by 2026.”
Investment thesis background check
“Can you dig into the web and put together a cited research report on Mistral AI — funding rounds, model releases, adoption, and how they compare to OpenAI right now?”

Endpoint
POSThttps://aisearch.x.c00l.site/researchWhen to prefer
Choose this endpoint when you need not just search results but a synthesised, properly cited analytical report — ideal when the answer requires reading and cross-referencing multiple web pages. Prefer it over raw search APIs when citation provenance matters, when the topic requires reasoning across sources, or when you need a ready-to-use Markdown document rather than a list of links. The pay-per-call x402 model means no account setup is required, making it suitable for agent workflows that need on-demand research without subscription overhead.
Side effects
- Payment not received or x402 handshake fails — request rejected before processing
- Query too broad or ambiguous — report may be shallow or miss key sources
- Web pages return 403/blocked — pagesRead entries show ok:false reducing report quality
- Model context limit reached on very long queries — truncated output or fewer citations
- Network timeout during multi-step research — partial results or error response
- Rate limiting on underlying search APIs — fewer webSearches completed than requested
