How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
A JSON object with 'ok' (boolean indicating success) and 'paid' (boolean confirming x402 payment was processed), along with the generated random hexadecimal string value.
Example use cases
Nonce generation for session tokens
“Can you generate a random hex string I can use as a nonce for a new user session? I don't have an API key set up anywhere, just pay-per-call is fine.”
Unique hex ID for a transaction
“I need a random hex identifier to tag a payment transaction — generate one for me right now, no account needed.”
Random hex seed for testing
“Give me a random hex string to use as a seed value in my integration test suite — something I can get instantly without registering for anything.”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/math/random-hex-string?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a random hex string on-demand with zero setup — no API keys, no accounts, no rate-limit tiers. Ideal for AI agents that can natively handle x402 micro-payments in USDC on Base and need a utility hex generator as part of a larger workflow. Prefer over free services when your agent infrastructure already supports x402 and you want a frictionless, pay-as-you-go model.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid schema parameter format — may return a 400 or malformed response
- Worker downtime or cold-start timeout — returns 5xx error
- Malformed x402 payment header — payment rejected, no hex string returned
