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 JSON object containing: a Markdown brief (150-500 words) where every paragraph cites its source pages by ID; an array of key_facts each with a verbatim quote and the URL it was found in; a sources array listing each fetched page with its title and character count; token usage counts; word count; and a disclaimer. Only quotes found verbatim in the fetched pages are included.
Example use cases
DeFi protocol research digest
“Write me a sourced 400-word brief on Aave V3's lending mechanics, pulling from https://docs.aave.com/faq and https://aave.com, with verbatim quotes for the key facts and paragraph-level citations.”
Competitive landscape overview
“Give me a 300-word cited brief on the current state of Ethereum layer 2 scaling solutions, using https://l2beat.com and https://ethereum.org/en/layer-2 as sources, with every key fact quoted word-for-word from the pages.”
Topic primer for due diligence
“I need a quick sourced brief on Coinbase's Base network — around 250 words — with paragraph citations and verbatim quotes pulled from https://base.org and https://coinbase.com/blog.”
Technical details
Endpoint
POSThttps://aiworker.duckdns.org/v1/brief/topicWhen to prefer
Choose this endpoint when you need a verifiably sourced, citation-rich brief rather than a raw LLM answer — especially when you want to supply your own authoritative URLs and need every key claim backed by a verbatim quote found in the actual page text. It is ideal for research digests, due diligence summaries, and agent-generated reports where hallucination risk must be minimized. Prefer alternatives if you need real-time data, structured data extraction, or a plain-text scrape without synthesis.
Side effects
- Source URL is inaccessible or returns non-200 — that source is skipped or marked ok:false
- Topic is empty or exceeds 200 characters — request rejected
- No verifiable verbatim quotes found — key_facts array may be empty
- All provided URLs are unreachable — brief may rely solely on Wikipedia
- max_words out of range (below 150 or above 500) — validation error
- Payment not included or insufficient — 402 Payment Required
