How this service works
Deterministic-first data for agents, paid per call in USDC over x402 v2: DeFi yields, Base token and wallet cards, Polymarket odds and backtests, news, fact checks, cited briefs. 20 routes, $0.005-$1
Output
A structured JSON object containing a Markdown report with inline citations, an array of key findings (each with a quote, finding summary, and source URL), a list of sources read (with title, URL, and publication date), a list of unanswered questions, word count, token usage, model used, number of search rounds, and a disclaimer noting the report is informational only.
Example use cases
DeFi yield change investigation
“I need a cited research report on how Aave's USDC yields on Base have changed over the past 30 days and what's driving it — crypto focus, around 600 words please.”
Polymarket event deep dive
“Can you research what the current Polymarket odds are on the Fed cutting rates in Q3 and why — pull recent sources, markets focus, max 1000 words.”
General news fact-check brief
“Do a deep research brief on the latest news around the EU's AI Act enforcement actions in 2025 — general focus, last 60 days, and flag anything that couldn't be verified.”
Technical details
Endpoint
POSThttps://aiworker.duckdns.org/v1/research/deepWhen to prefer
Choose this endpoint when you need a multi-source, cited research brief rather than a single data lookup — especially for nuanced crypto, DeFi, or market questions where you want evidence, attribution, and explicit flagging of what could not be verified. Prefer it over simpler data routes (price feeds, yield tables) when the question requires synthesis across several web sources. The focus enum lets you bias retrieval toward crypto/DeFi sources, financial markets, or general web.
Side effects
- Question too short or too long (minLength 10, maxLength 500) returns validation error
- Source URLs malformed or not HTTPS cause schema rejection
- Requested sources unreachable or blocked return partial results with failed source flagged
- recency_days outside 7–365 range causes parameter rejection
- No relevant web content found returns report with empty key_findings and populated unanswered list
- Payment failure over x402 results in 402 response before research begins
