Live EVM transaction status and receipt lookup. Give a transaction hash + chain and get back whether it mined successfully, reverted, or is still pending in the mempool, plus block number, confirmations, timestamp, sender and recipient, value transferred (native unit), gas used, effective gas price, total fee paid, any contract created, and event-log count. Chains: base, ethereum, polygon, arbitrum, optimism. Real-time post-training chain state — use it to confirm a payment settled, detect a reverted transaction, or wait for confirmations before acting. Unknown hash returns 404. Sibling of /api/crypto/gas-oracle (fees) and /api/crypto/address-validate (format).
Start with a quote-only recipe. Payment signing stays in your project.

// A valid 402 is a quote, not a completed paid call.This sends no payment. Inspect the 402 response before adding a wallet-enabled client.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
