How this service works
EVM Receipt Status Check: EVM Receipt Status Check normalizes receipt status values into success or failure from bounded caller-supplied values without an external provider. Call EVM Receipt Status Check before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Receipt Status Check as versioned deterministic JSON. Price: $0.…
Output
Returns a JSON object containing the interpreted status integer, a boolean 'success' flag indicating whether the transaction succeeded, a 'status' field of 'pass' or 'fail', the operation name, and evidence metadata including whether the input was retained and the SHA-256 hash of the input.
Example use cases
Pre-process on-chain payment confirmation
“I just got back a receipt from an Ethereum transaction — the status field is '1'. Can you verify whether that means it actually succeeded before I mark the order as paid?”
Smart contract call failure detection
“My agent received a receipt status of '0' from a smart contract interaction. Run an EVM receipt status check on it so I know if the call reverted and I should retry.”
Automated blockchain workflow gating
“Before the next step in my agent pipeline, validate this EVM receipt status value '1' to confirm the on-chain step completed successfully.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-receipt-status-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs a fast, governed, in-memory check of an EVM receipt status code without spinning up a full blockchain node or SDK. Ideal for lightweight preflight validation within automated agent pipelines where you only have the status integer and need a reliable pass/fail interpretation with audit evidence.
Side effects
- Missing or empty 'status' field returns a validation error
- Non-numeric or malformed status string may produce unexpected results
- Network timeout on the Delx API returns a 5xx error
- Invalid input type (non-string) may cause schema validation failure
