How this service works
One-call ALLOW, WARN, or BLOCK trade-risk decisions for Base agents, combining contract safety with live DEX liquidity and activity. Paid per result in USDC over x402.
Output
A JSON object containing a synthesized natural-language answer to the query, an array of citations (each with URL, title, source domain, publication date, and citation number), the number of sources read, the LLM model used, the provider name, and a timestamp.
Example use cases
Research a new DeFi protocol
“Can you look up recent information about Aerodrome Finance on Base — what's their current TVL situation and any major updates from the last week? Use 4 sources.”
Fact-check a crypto claim
“I heard that Base surpassed Ethereum in daily transactions last month — can you research whether that's true and give me cited sources from the past month?”
Answer a question about x402 payments
“What is the x402 payment protocol and how do AI agents use it to pay per API call? Search the web for a current answer with up to 5 sources.”
Technical details
Endpoint
GEThttps://base-intel-api.jakemaxsigal.workers.dev/research?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs live, cited web research with a synthesized answer — especially for questions about current events, recent DeFi developments, or any topic requiring up-to-date sources. It is particularly well-suited for Base/crypto research given the sibling endpoints on the same service. Prefer it over static knowledge bases when recency matters and source attribution is required.
Side effects
- Question exceeds 300 character limit — query is truncated or rejected
- Invalid recency value (not day/week/month/year) — may cause unexpected filtering
- Sources count outside 1-5 range — default of 4 applied or error returned
- Payment not completed via x402 — 402 response requiring USDC payment before result is returned
- No recent sources found for narrow recency filter — answer may be incomplete or empty citations
