Pricing
Pay per request
No account, no subscription and no API key. Your agent pays for each request in USDC on Base, using the x402 protocol. The price is stated in the 402 response before anything is paid.
| Service | Endpoint | Price | What you get |
|---|---|---|---|
| Fact check | POST /api/x402/fact-check | $0.05 | A verdict on one claim (true, false, partly true or unverified), a one-sentence answer and its source. |
| Quick research | POST /api/x402/research | $0.25 | A sourced answer to one question: key points, sources, a confidence rating and anything unverified. |
| Data analysis | POST /api/x402/analyze | $0.20 | The answer to a question about your data (CSV, JSON or a link to a file), with the exact code that computed it. |
| Lead research | POST /api/x402/leads | $1.00 | Up to 3 companies matching your description, with every requirement checked and sourced. |
You only pay for results. Payment settles only after a successful response. Invalid requests (400) and requests that could not be completed (502) are never charged.
