Straelo Relay Transaction Intelligence
x402
Straelo Relay Transaction Intelligence is a paid API for AI agents from relay.straelo.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).
Analyzes an EVM transaction hash on Ethereum or Base and returns decoded intelligence including execution status, gas metrics, method selector, value transferred, and log counts.

How this service works
Retrieve a Base or Ethereum transaction and receipt in one paid request, with deterministic execution status, transaction classification, method selector, gas cost, logs count and raw RPC evidence.
Output
A JSON object containing the decoded transaction analysis: execution_status (success/failure), gas_used, gas_limit, effective_gas_price, total_fee_wei, total_fee_native, value_wei, value_native, method_selector, logs_count, contract_created, transaction_type, plus the raw receipt and transaction objects, provider name, and latency_ms.
Example use cases
DeFi trade execution audit
“I just sent a token swap on Base with hash 0xabc123...def456 — can you tell me if it succeeded, what method was called, how much gas it consumed, and the total fees in ETH?”
Smart contract deployment check
“Check this Ethereum transaction 0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef — I want to know if it deployed a contract and what the execution status was.”
On-chain payment verification
“Someone claims they paid me on Base; the tx hash is 0xdeadbeef00000000000000000000000000000000000000000000000000cafebabe — can you verify how much ETH was transferred and confirm the transaction succeeded?”
Technical details
Endpoint
POSThttps://relay.straelo.com/transaction-intelligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, structured intelligence about a specific EVM transaction on Ethereum or Base, particularly when you need decoded fields like method_selector, gas metrics, value transferred, and execution status in a single call. Prefer it over raw RPC eth_getTransactionReceipt calls when you want pre-parsed, agent-ready JSON with fee calculations already normalized to native units.
Side effects
- Invalid tx_hash format (not a 64-char hex with 0x prefix) returns validation error
- Transaction hash not found on the specified chain returns not found error
- Unsupported chain value (anything other than 'ethereum' or 'base') returns schema validation error
- Network or RPC timeout may cause elevated latency or 5xx error
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
