Delx Commerce — EVM Hex Data Normalize
x402
Delx Commerce — EVM Hex Data Normalize is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Normalizes raw data into valid, prefixed EVM hex format and returns byte count, with no data retention.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing: the normalized 0x-prefixed hex string, the byte count, a status field ('pass'), the operation name, and an evidence block confirming no external calls were made and no input data was retained (includes SHA256 of the input for auditability).
Example use cases
Preflight calldata before contract call
“I'm about to send a transaction to an Ethereum smart contract — can you normalize this calldata string 'a9059cbb000000000000000000000000' into valid EVM hex and tell me its byte length before I submit?”
Validate hex encoding in a pipeline
“Before I pass this data into my on-chain pipeline, can you normalize it to make sure it has the right 0x prefix and is properly hex-encoded: 'deadbeef0011'?”
Debug malformed transaction input
“I think my transaction input data might be malformed — can you run '00112233aabbcc' through the EVM hex normalizer to check it and get the byte count back?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-hex-data-normalize?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, verifiable, pay-per-call utility to normalize EVM hex calldata before submitting blockchain transactions. It is ideal for agent pipelines that require auditability (SHA256 evidence, no-retention proof) without standing up infrastructure. Prefer it over manual normalization when you need deterministic results with a verifiable audit trail.
Side effects
- Input data exceeds 8192 character limit — request rejected
- Malformed or non-hex input that cannot be normalized — returns error status
- Payment failure via x402 — 402 response before processing begins
- Network timeout or service unavailability
