How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing: 'hex' (the 0x-prefixed hexadecimal encoding of the input text), 'mode' (encoding mode, e.g. 'text_to_hex'), 'valid' (boolean indicating successful encoding), 'schema' (schema identifier string), 'truncated' (boolean indicating if input was truncated), and 'byte_length' (integer count of encoded bytes).
Example use cases
Hex-encode smart contract calldata
“I need to hex-encode this UTF-8 string 'transfer:0xabc123' so I can embed it in a blockchain transaction — what's the hex output and byte length?”
Debug binary payload representation
“Can you convert the string 'Content-Type: application/json' to its hexadecimal byte representation so I can verify what's actually being sent over the wire?”
Encode text for cryptographic hashing
“Hex-encode the text 'delx_api_key_2024' for me so I can pass it into a hash function that expects hex input.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/bytes-hex-encode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-signup hex encoding service paid in USDC via the x402 protocol — ideal for AI agents that need verifiable, metered utility operations without API key management. Prefer this over self-implemented encoding when you want a canonical, schema-versioned result with validity confirmation and byte length metadata attached.
Side effects
- Empty or missing 'text' field returns an error or invalid result
- Extremely long input strings may be truncated (truncated: true in response)
- Non-UTF-8 byte sequences in the input string may cause encoding errors
- Network or payment failures (x402 protocol) may prevent the call from completing
