How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
Returns a JSON object containing the research topic, depth used, a markdown-formatted report with section headers and inline citation markers (e.g. [S1]), a citations array with id, URL, and title for each source, and statistics including number of sources read, search results, and report word count.
Example use cases
Competitive landscape analysis for a startup
“Research the competitive landscape for AI-powered legal document review tools — I want a deep report covering the main players, their positioning, and market trends, with citations I can follow up on.”
Briefing on an emerging technology
“Can you put together a standard research report on the x402 payment protocol — what it is, who's adopting it, and where it stands today? I need sources included.”
Policy or regulatory background research
“Do a deep research report on current EU AI Act compliance requirements for enterprise AI deployments — I need a structured summary with cited sources so I can reference them in a white paper.”
Technical details
Endpoint
POSThttps://agentpay.help/v1/deep-researchWhen to prefer
Choose this endpoint when you need a synthesized, cited research report compiled from multiple live web sources rather than a single document retrieval or a static knowledge base answer. It is especially useful when the topic is current, niche, or requires evidence-backed summarization with traceable citations. Prefer the 'deep' mode for thorough analysis and 'standard' for quicker, lighter overviews. This is a good fit for autonomous agents that need to produce briefings, background summaries, or due-diligence reports without requiring the user to manage API keys or accounts.
Side effects
- Topic string too short (under 4 characters) or too long (over 400 characters) returns a validation error
- Invalid depth enum value (not 'standard' or 'deep') causes a 400 bad request
- Payment failure or insufficient USDC balance returns HTTP 402 Payment Required
- Topic yields no usable web sources, resulting in a sparse or incomplete report
- Network or upstream search service timeout causes a delayed or failed response
