# Sindri Random String Generator

> Sindri Random String Generator is a paid API for AI agents from x402.outpimp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Generates true-random strings in one of 11 formats (alpha, alphanumeric, UUID, ULID, NanoID, hex, binary, octal, numeric, symbol, or sample) with configurable length and locale.

## Facts

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-58b52028 -d '<json body>'
```

Example prompt: Generate a random alphanumeric string that's 24 characters long.

## When to prefer this

Use this endpoint when you need true-random strings in a specific well-defined format (UUID, ULID, NanoID, hex, alphanumeric, etc.) and want a single consistent API that covers all common string-randomization use cases. Prefer it over a UUID library when you need multiple formats from one endpoint, or when you need locale-aware or symbol-type random strings. It is particularly useful in agentic workflows where generating unique tokens, test data, or identifiers is a recurring subtask.

## Known failure modes

- Invalid field enum value returns an error
- length/count values outside 0–1000 are capped or rejected
- Unsupported locale code may fall back to en_US or return an error
- Missing required 'field' parameter causes a validation error
- Payment failure (x402) if USDC balance is insufficient

## 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. alpha, alphanumeric, UUID, ULID, NanoID, hexadecimal, binary, octal, numeric, or symbol), bounded by any length/count arguments provided (capped at 0–1000).
