# Sindri Random String Generator

> Sindri Random String Generator is a paid API for AI agents from ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Generates true-random strings in various formats (alpha, alphanumeric, UUID, hex, binary, nanoid, etc.) with optional locale and length controls.

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 sindri-random-string-generator-91215ca4 -d '<json body>'
```

Example prompt: Generate a random alphanumeric string that's 24 characters long for me to use as a session token.

## When to prefer this

Choose this endpoint when you need cryptographically or truly random strings in a specific format (UUID, ULID, nanoid, hex, binary, etc.) without standing up your own random number infrastructure. Ideal for generating tokens, session IDs, slugs, keys, or test data at low cost ($0.01/call). Prefer over client-side random when auditability or server-side generation is needed.

## Known failure modes

- Invalid 'field' enum value returns an error — must be one of: alpha, alphanumeric, binary, octal, hexadecimal, numeric, sample, uuid, ulid, nanoid, symbol
- length or count exceeding 1000 is capped or rejected
- Invalid locale code may fall back to en_US or return an error
- Malformed args object for the chosen field method may cause a validation error
- Payment failure ($0.01 USDC) will prevent the call from completing

## How this service works

True-random-string generator API. Generates a bounded random string via one of: alpha, alphanumeric, binary, octal, hexadecimal, numeric, sample, uuid, ulid, nanoid, symbol. Accepts optional locale (default en_US). length/count-style args are capped to 0-1000.

## Output

Returns a randomly generated string in the requested format (e.g. UUID like '550e8400-e29b-41d4-a716-446655440000', hex like 'a3f9b2...', alphanumeric like 'Xk7mQ2...'), bounded by the length/count args provided (max 1000).
