How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

Output

A JSON object containing a cited natural-language answer to the question, an array of citation objects (each with URL, index number, and a text snippet), a session token for the RAG session, a reference to the persisted markdown artifact stored at a retrievable URL, and a list of completed pipeline steps (safe-extract, persist, outcome/answer).

Example use cases

Example prompt

“Look up https://arxiv.org/abs/2310.06825 and answer the question 'What are the main contributions of this paper?' with citations — use top_k of 5 and keep safety filtering on.”

When to prefer

Choose this endpoint when you need to ask a specific question about the content of a known URL and get back a cited, grounded answer — not just a summary. It is especially suited for research tasks where traceability to source snippets matters. It combines web fetching, safety filtering, RAG indexing, and LLM Q&A in a single call, saving orchestration overhead. Prefer it over generic web scrapers when you need answer + citations rather than raw text, and over general search APIs when you already know the source URL.

Side effects

URL is unreachable or returns non-200 — extraction step fails with an error
Content flagged by Llama Guard safe-extract — pipeline halts early with safety rejection
RAG index upload times out or fails — answer step cannot proceed without index
question is empty or too vague — answer may be low quality or generic
Payment rejected or insufficient USDC balance — 402 response before processing begins
top_k out of range (must be 1-20) — validation error
budget.max_queries or max_index_ops out of allowed range — validation error
