Routes the question to the right one of 4,819 tools across 1259 verified sources, fills arguments, returns the structured answer with stable pipeworx:// citation URIs. Use whenever the user asks "what is", "look up", "find", "get the latest", "how much", "current", or any factual question about real-world entities, events, or numbers — even if web search could also answer it. Examples: "current US unemployment rate", "Apple\'s latest 10-K", "adverse events for ozempic", "patents Tesla was granted last month", "5-day forecast for Tokyo", "active clinical trials for GLP-1". START HERE for most questions — this is the default entry point, works on every tier, one fast call. Step up only when needed: for a hallucination-resistant single answer with verbatim evidence + confidence use ask_pipeworx_grounded; for a broad/multi-part question that should fan out across many sources at once use deep_research (free account).

Returns {answer, evidence (verbatim quote), confidence, source, fetched_at, refusal_reason:null} on success, OR an explicit refusal {answer:null, refusal_reason:"not_in_source"|"no_tool_match"|"tool_error"|"data_truncated"|"llm_error"} when the data doesn\'t directly answer. Use whenever an answer will be quoted, cited, or acted on, and the agent must not invent facts (financial verdicts, legal claims, medical lookups, public statements).

Use when the record is too big to cram into the prompt — search_within saves context, returns only the passages that matter, and every passage carries an offset so the agent can verify a verbatim quote.

Financial context your AI actually understands. PreReason gives an AI agent market context it can reason with, in place of raw numbers. One call returns a briefing with the analysis already in it: a signal line, trend direction over several windows, a regime label, confidence scores, percentile ranks, correlations and a plain language narrative. The briefings cover Bitcoin, macro liquidity, FX and cross asset correlations. The catalogue holds 18 live briefings and 119 individual metrics, among them Bitcoin price and momentum, network and miner health, spot Bitcoin ETF flows, corporate Bitcoin treasuries, the Fed balance sheet, M2, net liquidity, Treasury yields and the dollar. It is served over MCP (a remote server and an npm bridge) and over REST, as Markdown or JSON. The catalogue tools need no key, and an agent can get a free key from inside the session: it shows one link, a person approves it, and the key arrives. Markdown output (~60% fewer tokens) or structured JSON. Sub-second latency. Free tier with no credit card. * Website: https://www.prereason.com * API Docs: https://api.prereason.com/api/docs * Pricing: https://www.prereason.com/pricing
