KEVAREMESH Secure Random Number Generator
x402
KEVAREMESH Secure Random Number Generator is a paid API for AI agents from kevaremesh-web.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-28).
Generates cryptographically secure random values (hex bytes and/or bounded integers) using Web Crypto getRandomValues

How this service works
Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.
Output
Returns a JSON object containing: a hex-encoded random byte string (length determined by 'bytes' param), the number of bytes generated, optional random integer bounded by min/max, the randomness source label ('Web Crypto getRandomValues'), a product/service identifier, generation timestamp, and any limitations such as the absence of a public randomness beacon.
Example use cases
Random nonce for transaction signing
“I need a secure 64-byte random hex nonce to use as a salt before signing a blockchain transaction — can you generate that for me?”
Random dice roll with secure entropy
“Simulate a fair dice roll giving me a secure random integer between 1 and 6, and also include the raw 16-byte hex so I can verify the entropy source.”
Random token for session ID generation
“Generate a cryptographically strong 32-byte random hex string I can use as a unique session token, and also give me a random integer between 100000 and 999999 for a one-time PIN.”
Technical details
Endpoint
POSThttps://kevaremesh-web.vercel.app/api/x402/secure-random-cdp-secure-random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically secure random values with an auditable paid-API trail, particularly for blockchain, cryptographic, or security-sensitive workflows. Prefer it over free or pseudo-random sources when verifiability and entropy quality matter. It is well-suited for AI agents that need random values as part of automated signing, token generation, or simulation pipelines, and when a cost-per-call model is acceptable for quality assurance.
Side effects
- bytes parameter exceeds 1024 — returns validation error
- min greater than or equal to max when integer range is requested — returns error
- Payment not included or invalid — returns 402 Payment Required
- bytes parameter missing or non-integer — returns schema validation error
- Service unavailability on Vercel edge — returns 500 or timeout
