How this service works
EVM Hex Data Normalize: EVM Hex Data Normalize normalizes even-length EVM hex data while preserving byte boundaries from bounded caller-supplied values without an external provider. Call EVM Hex Data Normalize 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 Hex Data Normalize as versioned deterministic JSON. Price:…
Output
Returns a JSON object with the normalized hex string (0x-prefixed), the byte count of the data, the operation name, processing status ('pass'), and an evidence block confirming no data retention, no external calls, and the SHA256 hash of the input.
Example use cases
Preflight calldata before on-chain submission
“Before I send this transaction, normalize my calldata into valid EVM hex and tell me how many bytes it is: 'abcd1234ef'.”
Validate hex encoding for smart contract call
“Can you take this payload and make sure it's properly formatted as EVM hex with a 0x prefix? Here's the data: '00ff7a3b'.”
Compute byte count of EVM transaction data
“I need to know the byte count of this EVM data before estimating gas — can you normalize it and return the byte length? Data: '0x1a2b3c4d'.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-hex-data-normalizeWhen to prefer
Choose this endpoint when you need a reliable, auditable, stateless utility to normalize EVM hex data before submitting on-chain transactions, estimating gas, or passing calldata to smart contracts. Prefer it when you need both normalization and byte-count in a single call with a verifiable evidence trail (SHA256 of input, no retention guarantee).
Side effects
- Input data exceeds 8192 character limit — request rejected
- Malformed input that cannot be interpreted as hex — error response
- Empty or null data field — may return error or zero-byte result
- Non-string input type — schema validation failure
