How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a 'data' field containing citation search results, a 'status' field indicating success, and an 'roi_proof' object showing compression ratio (e.g. 91.4% compression), indicating how much raw data was condensed into the response.
Example use cases
Academic literature research assistant
“Find me citations and references for the topic 'climate change impact on coral reefs' — I need sources I can use in a research paper.”
Bibliography building for a report
“Search for cited works on 'CRISPR gene editing ethics' so I can build a bibliography for my report.”
Verifying source coverage on a topic
“Look up citations for 'decentralized finance smart contracts' and tell me what sources come up — I want to know how well-covered this topic is in the literature.”

Choose this endpoint when you need to search for citations or references on a topic and want a cost-effective, pay-per-call model ($0.01 USDC) with deterministic results and built-in compression metrics. Useful for agents that need citation lookup without maintaining a persistent subscription to a research database.
