Give an agent a claim and a source. TruthPal checks whether the evidence actually supports it, contradicts it, or simply isn't enough.
AI agents increasingly need to make decisions from information they find online. TruthPal gives them a simple way to check whether a supplied source actually establishes a claim.
TruthPal is deliberately narrow. It doesn't try to become an all-knowing search engine. It checks the evidence you've given it.
Your agent sends a claim and the public source URL it wants checked.
TruthPal retrieves the source and evaluates what the evidence actually establishes.
Your agent gets structured JSON: supported, contradicted, or uncertain, with evidence and confidence.
TruthPal evaluates the supplied source rather than quietly filling gaps with outside knowledge.
Structured JSON makes verification results easy for agents and applications to consume.
No monthly subscription is required. Agents can pay for verification when they actually need it.
A good pal has your back.
TruthPal makes sure the evidence does too.
TruthPal is designed to sit inside an agent's workflow. Send a claim and a public source URL, then receive a structured verification result.

Designed for agents. x402 handles payment at the HTTP layer, so a machine can pay for a verification without a human checkout.
TruthPal Verify is built around x402 payments. No account, dashboard or monthly subscription is required for the API.
