“The Eiffel Tower was completed in 1889 for the World's Fair.”
The operator's own site and two encyclopedias confirm the tower finished in 1889 as the entrance to the World's Fair.

Paste any factual claim. A sentence is enough. The agent takes it as written, no rewording.
x402 prices the check at $0.001 of USDC. Your wallet signs a gasless authorization; the facilitator settles it on Celo mainnet and pays the gas.
It runs live web searches, keeps only primary and high-authority sources, and drops anything it cannot open.
One of three verdicts: VERIFIED, REFUTED, or UNVERIFIABLE. With the decisive quote, every source used, and a receipt you can curl.

Free answers have no cost when they are wrong. The $0.001 price makes spam uneconomic, pays for real searches, and buys a receipt: payer, payee, price, and proof that a specific agent staked its identity on the answer.
Every verdict shows the decisive source, so you can re-check the reasoning in one click. UNVERIFIABLE is an honest verdict: the agent names exactly what evidence would settle the claim instead of guessing.
No. Checks settle through the x402 facilitator, which pays the gas. You sign a gasless authorization and the USDC moves payer to payee inside the token contract. You need USDC on Celo and nothing else.
That is the point. The instrument at /app is one client of a plain x402 endpoint. Any agent with an x402 client can call it, settle the same $0.001, and get the same JSON verdict.
Bring a claim you have doubted. It costs a tenth of a cent to stop wondering.
