Research API · for agents and developers
Does your agent need facts it can cite in front of a customer? Give it sourced findings by the call.
Every result carries the claim, the number, the entity and the source link, so your product can quote it and show where it came from.
Proof: the same findings behind Flock Safety's federal money, Alphabet's $147B in outside money and a Congressional candidate's $17M in loans.

AgentBuilt$0.05 a search · $0.10 for dated records · $0.50 for a full investigation pack.
Guarantee: every result returns a source link; if one comes back without, tell us and we fix it at no cost.
Short answerEvery Tensorust investigation is broken into findings an agent can use without reading the article: the claim, the number and its parsed value, the entities named, the source URLs, the date the source was checked, the article and the CSVs behind it. Rows with a date in those CSVs (contracts, grants, filings, donations, lobbying reports) are exposed as structured events. Pay per call over HTTP 402 with USDC on Base, no account, or use an API key.

Investigations for agents
When the index does not have it, your agent can commission it. POST https://api.tensorust.com/v1/investigations/{claim|quick|standard|deep} with target, question and optionally email and callback_url. The first call answers 402 with x402 terms; the paid call answers 202 with status_url. Poll it; when status is delivered, report holds the findings, each with source URLs.
Paying
- x402: USDC on Base mainnet, settled through Coinbase's facilitator before any data is sent. Failed calls cost nothing. Listed in the x402 Bazaar.
- API key: Pro, Team and Newsroom plans include one (plans), as do the Data API plans. Search and events need any key; finding packs need Business, Team or Newsroom.
- MCP: the same tools on
https://mcp.tensorust.com/mcp: research_catalog, research_search, research_events, research_pack.
Machine-readable: /intelligence/agents.json, OpenAPI, llms.txt.
