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 original hex input, a boolean 'valid' field indicating whether it conforms to hex shape, and a schema identifier string ('delx/util-is-hex-shape/v1').
Example use cases
Blockchain address format check
“Before I submit this transaction, can you verify that '0x1a2b3c4d5e6f7890abcdef1234567890abcdef12' is actually a valid hex-shaped string?”
Color code hex validation
“I have this color value '#ff5733' — can you tell me if it follows a valid hex format?”
Encoded data pre-flight check
“I'm about to pass '0xdeadbeef' as a parameter — can you confirm it's properly hex-shaped before I use it?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/is-hex-shape?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call hex format validation with no signup overhead, especially in agent pipelines that require verifiable, on-chain-payable utility calls over USDC. Ideal when you need a quick boolean check on whether a string is hex-shaped before passing it to blockchain or encoding workflows.
Side effects
- Missing 'hex' field in request body returns an error
- Non-string input types may cause validation failure or error
- Empty string may return valid: false
- Payment not included or insufficient USDC results in 402 response
