How this service works
One pay-per-call API for AI agents: optimization, AI, research, on-chain data, and automation — all settled in USDC on Base via x402. Discover via MCP and Bazaar, estimate free, pay per call. No API keys, no signup.
Output
Returns a JSON object containing a synthesized briefing text with inline numbered citations, an array of source objects (URL, title, source name), the original query, pricing metadata (price in USD, currency, provider cost), and the idempotency request key. The briefing is described as grounded — meaning claims are tied to cited sources.
Example use cases
Technical topic deep-dive for agent
“Give me a sourced research briefing on the current state of solid-state battery technology — pull 5 sources and use request key 'battery-brief-001' so I can reuse it.”
Current events synthesis with citations
“I need a grounded briefing on recent US semiconductor export restrictions to China, up to 5 sources, with request key 'semicon-policy-001'.”
Competitive landscape research
“Can you generate a research report on the top AI coding assistant tools in 2024, with 8 sources cited, using request key 'ai-coding-tools-report'?”

Endpoint
GEThttps://api.cortexcloud.org/v1/research/report?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a synthesized, source-cited research briefing on a specific topic and requires verifiable references rather than raw web results. It is ideal for agentic workflows where no signup or API key management is desired, payment is handled autonomously via x402/USDC on Base, and idempotent retrieval (via request_key) is needed to avoid duplicate charges for the same query. Prefer it over general search APIs when a narrative synthesis with numbered citations is the desired output format.
Side effects
- Query too short or empty — violates minLength:1 constraint
- Query exceeds 400 characters — rejected by maxLength
- Count outside 1–10 range — rejected by min/max constraints
- Request key shorter than 8 chars — violates schema constraint
- Payment not settled via x402/USDC — 402 Payment Required returned
- Same request_key with different payer returns stored report from original payer
- No relevant sources found for obscure query — briefing may be sparse or empty
- Network timeout if underlying web sources are slow to respond
