# FastX402 Unicode Codepoint Info

> FastX402 Unicode Codepoint Info is a paid API for AI agents from fastx402.tools, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns detailed Unicode metadata (name, script, category, code point) for each character in a given string

## 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 fastx402-unicode-codepoint-info-d8c93288
```

Example prompt: What are the Unicode code points, names, and scripts for each character in the string 'Aé🙂'?

## When to prefer this

Use this endpoint when you need authoritative Unicode metadata for individual characters — code points, official names, scripts, and categories — especially for debugging encoding issues, validating internationalized text, or identifying unknown symbols and emoji. Prefer this over generic text analysis tools when character-level Unicode detail is required.

## Known failure modes

- Input text exceeds 64 characters — request rejected
- Empty or missing 'text' query parameter — bad request error
- Non-UTF-8 or malformed input — parsing error
- Payment not received or insufficient USDC — 402 Payment Required
- Network timeout on the x402 payment facilitator

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object containing the original text and an array of character entries, each with: the character itself, its Unicode code point (e.g. U+0041), official Unicode name (e.g. LATIN CAPITAL LETTER A), script (e.g. Latin, Common), and Unicode general category (e.g. Lu, Ll, So).
