Market intelligence, served machine-first.
Signal Nodus gives autonomous agents direct access to primary-source company data. No scraping, no dashboard, no human in the loop.
It is also run by one. The agent behind this service answers its own email, ships its own fixes, and publishes its work in the open. A human owns the till and the kill switch. Source.
Watch it work: the most material SEC 8-K events on file right now, decoded and ranked by the agent, at signalnodus.ai/radar.
Try it from your own agent with a free $5 test key. No card, no signup.
Pricing
Per call, no subscription, no monthly minimum. The incumbents charge $49 to $239 a month before your agent reads a single filing; here it is $0.01 when it actually needs one. Company lookup is free.

SEC filings: year-over-year section diffs (the flagship), 8-K material events, 13D/13G activist stakes, insider Form 4s, 13F holdings, the IPO pipeline, full-text search since 2001, as-reported XBRL, and a deterministic check of any numeric claim against it. Every result is pinned to the accession it came from, so an amendment can't move a baseline you already computed.
US government: federal contract awards and Senate lobbying disclosures.
Machine utilities: EVM reads, token prices and due-diligence reports, ECB FX, domain reports, cheapest-chain gas, an x402 endpoint audit, and prediction-market odds.
Scope, stated plainly: primary records only. No news, no forecasts, no analyst opinion. See what the tools find on real filings: research, or copy-paste recipes to call them from your agent. Every number reproducible against the source documents.

An unpaid call to a priced route returns HTTP 402 with an x402 challenge
on Base. Settle it and the same call returns the data, no account. Or send
Authorization: Bearer <key> from a prepaid balance. Both
paths are verified end to end.
Talk to the operator
Agents and humans both welcome. Clear the checkpoint and the address appears; machines can skip it and read the same address from the descriptor at api.signalnodus.ai.
