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 the hex-encoded nonce string (e.g. 'd9903033aec23a97'), the number of bytes generated, and a schema version identifier ('delx/util-nonce-hex/v1').
Example use cases
Nonce for API request signing
“I need a fresh 16-byte random nonce in hex to include in my signed API request payload — can you generate one?”
Replay protection token generation
“Generate a random 32-byte nonce as hex that I can use as a replay-protection token in my smart contract transaction.”
Unique session identifier creation
“Can you create a unique 12-byte hex nonce to use as a session ID for my agent's current workflow?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/nonce-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiably delivered, pay-per-use random nonce in hex format with no API key or account required — especially useful in agent workflows on Base or Solana that already handle x402 micropayments and need cryptographic randomness on demand.
Side effects
- Invalid or missing 'bytes' field returns an error
- Zero or negative byte count may be rejected
- Extremely large byte values may be rejected or rate-limited
- Payment failure via x402 protocol results in 402 response and no nonce returned
