How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'data' field containing the fact-check search results, a 'status' field (e.g. 'ok'), and an 'roi_proof' object that includes a compression_ratio_pct value (e.g. 91.4) showing how much the output was compressed relative to raw source content.
Example use cases
Verifying a viral claim before publishing
“I need to fact-check the claim that 'humans only use 10% of their brains' before I include it in my newsletter — can you search for the truth and give me the distilled result?”
Research assistant reducing token cost
“Search and fact-check whether 'coffee causes cancer' and return the most compressed accurate summary you can — I need to keep my context window lean.”
AI pipeline grounding check
“Before my agent finalizes its answer, can you fact-check whether 'the Eiffel Tower is the tallest structure in France' and return a verified, distilled result?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/fact-check-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs to fact-check or search for information while aggressively minimizing token consumption. It is especially valuable in agentic pipelines where context window size is a bottleneck and you need a compression-ratio proof to confirm efficiency. Prefer it over raw web search when you want structured, distilled, verifiable output rather than raw HTML or unfiltered content.
Side effects
- Missing 'query' parameter returns empty or error data
- Unparseable or overly broad query may return low-quality results
- Payment failure via x402/USDC on Base blocks the request
- High compression ratio may omit nuanced context
- Service unavailability returns non-200 status
