Can I send this transaction

flat-rate-llm.kikoribera03.workers.dev · x402

Use when an agent is about to sign a transaction and must decide whether it will go through right now: one call that answers canSend with the facts behind it - the sender's balance, the gas this exact transaction needs, what it will cost, whether the node says it would revert, the nonce to use if earlier ones are still in flight, whether the destination is a contract, and how stale the chain head is. Replaces five separate reads. No API key, no account.

x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.
