How this service works
Hand over a whole research question and get one cited report back. The gateway plans sub-questions, runs multiple live web searches, reranks the sources by relevance, and synthesizes a ~1,500-word report with inline [n] citations and a source list - one payment, one outcome. Priced per report, not per call. Payable in USDC (x402/MPP) or by card (Stripe, >= $0.50 minimum - this clears it). Not cached (the web moves).
Output
Returns a JSON object containing: a full narrative report (markdown or JSON format) synthesized from multiple web sources, a list of cited sources with URLs, titles, relevance ranks, and snippets, a list of auto-generated sub-questions used to guide research, and metadata including the number of searches run, sources consulted, sources cited, and the synthesis model used.
Example use cases
Competitive landscape briefing for AI payments
“Research the competitive landscape for AI agent payment rails — I want a markdown report covering x402, MPP, and any other emerging protocols, with a focus on developer adoption and on-chain activity. Prefer sources from the last month.”
Due diligence report on emerging technology
“I need a thorough research report on zero-knowledge proof adoption in enterprise blockchain systems — cover use cases, major vendors, and recent regulatory signals. Format it as markdown and look at sources from the past year.”
Market research for investment memo
“Research the agentic AI tools market and give me a detailed report focusing on monetization models, pay-per-call APIs, and wallet-based identity trends — I want it in markdown with cited sources, pulling from any timeframe.”
Technical details
Endpoint
POSThttps://agent402.tools/v1/researchWhen to prefer
Choose this endpoint when you need a multi-source synthesized research report with citations rather than a single-document summary or a raw search result list. It is especially well-suited for agents that need to answer open-ended research questions, produce briefings, or investigate topics across many web sources in one call. Prefer it over raw search APIs when synthesis and citation quality matter, and over general LLM prompting when up-to-date sourced information is required. The pay-per-call, no-API-key model makes it ideal for agentic pipelines that need on-demand research without subscription overhead.
Side effects
- Query exceeds 2000 characters — request rejected with validation error
- No relevant sources found for highly niche or obscure queries — sparse or low-confidence report
- Recency filter too narrow (e.g. 'week') returns insufficient sources for synthesis
- Focus array exceeds 8 items — validation error
- Payment failure or insufficient USDC balance — 402 response, no report generated
- Synthesis model timeout on complex multi-faceted queries — partial or error response
