# Saylor Innovations Secure Random Number & Bytes Generator

> Saylor Innovations Secure Random Number & Bytes Generator is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Generates a cryptographically secure random integer within a user-specified range plus 1–64 random bytes returned as both hex and base64 strings.

## Facts

- Endpoint: GET https://saylorinnovations.com/api/x402/random?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-secure-random-number-bytes-generator-d35fa8f8
```

Example prompt: Give me a cryptographically secure random integer between 1 and 1000, plus 32 random bytes in both hex and base64 format.

## When to prefer this

Choose this endpoint when you need cryptographically secure randomness — a random integer in a bounded range combined with raw random bytes — in a single call. It is especially useful when you need both a numeric random value and raw entropy (as hex/base64) simultaneously, such as for nonce generation, seeding, or unbiased selection. It costs $0.01 USDC per call via the x402 payment protocol, so prefer it when trust in randomness quality matters more than cost.

## Known failure modes

- Invalid or out-of-range byte count (outside 1–64) may result in an error response
- Min greater than max yields an invalid range error
- Payment failure (x402 protocol) blocks access and returns a 402 status
- Network timeout or service unavailability returns a 5xx error

## How this service works

Secure random integer in a range plus random bytes as hex and base64

## Output

Returns a JSON object containing: the generated random integer (within the requested min–max range), the number of random bytes requested, those bytes encoded as a hex string, and those same bytes encoded as a base64 string, plus echoed min and max values.
