What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.fomox.tech controls every word below.

verify_payment

Check whether a crypto payment really settled and how much was ACTUALLY delivered, which is often not the amount the transaction claims. Use this before crediting anyone for an incoming payment.

cryptopaymentssettlementverificationblockchainread-only

list_chains

List every chain this service can verify, with the confirmation depth each needs before a payment is treated as final, and how deeply it can be verified. Call this if you are unsure whether a chain is supported or what to pass as `chain`.

cryptopaymentssettlementverificationblockchainread-only

list_failure_modes

List every known way a blockchain payment can appear successful while being worth less than it claims, or nothing at all. Each entry explains what the chain does, what it costs you when you get it wrong, and the one-line fix.

cryptopaymentssettlementverificationblockchainread-only

evaluate_spend_policy

Check a proposed payment against spending limits that live OUTSIDE your context, where no instruction in a prompt, a message or a web page can change them. Returns a signed allow or deny with reasons.

cryptopaymentssettlementverificationblockchainread-only

run_sandbox_case

Practise on a payment designed to deceive you, with no money at risk. Returns a verification result shaped exactly like a real one for one of 19 adversarial cases. Decide whether you would credit it, then call check_sandbox_answer to find out whether you were right and what the mistake would have cost.

cryptopaymentssettlementverificationblockchainread-only

check_sandbox_answer

Score your decision on a sandbox case. Tell it whether you would have credited the payment and for how much, and it replies with whether that was correct and, if not, exactly what the error would have cost you in real units. This is the fastest way to find out whether your payment handling is actually safe.
