# IranTools detect_format

> IranTools detect_format is a paid API for AI agents from irantools.johnaio281.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-22).

Detects the format and encoding of a given string value (e.g. base64, hex, JSON, Persian text, etc.)

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 irantools-detect-format-1a45bf94 -d '<json body>'
```

Example prompt: Can you detect what format or encoding this string is in: 'SGVsbG8gV29ybGQ='?

## When to prefer this

Use this endpoint when you need to programmatically detect the format or encoding of an arbitrary string value, especially in pipelines handling user-submitted data, Iranian/Persian text, or mixed-encoding scenarios. Prefer this over manual inspection or general-purpose libraries when you need a pay-per-call, no-signup solution that also handles Persian and Unicode edge cases.

## Known failure modes

- Empty string input returns an error or ambiguous result
- Very short strings may produce low-confidence or ambiguous format detection
- Strings with mixed encodings may not be classified cleanly
- Payment failure (402) if USDC balance is insufficient on Base
- Malformed request body (missing 'value' field) returns a 400 error

## How this service works

Persian and Iranian utilities for AI agents, plus general text/Unicode tooling. Jalali (Solar Hijri) calendar conversion, Iranian national ID / SHEBA / bank card / postal code / economic code validation, province and city lookup, official public holidays, Persian text normalization, keyword extraction, sentence splitting, similarity, HTML stripping, RTL fixing, Unicode homoglyph folding, script detection, NFC/NFD normalization, grapheme counting, date description, business-day counting, slugify, FNV-1a hashing, Shannon entropy, format and encoding detection, byte sizes. Pay per call in USDC on Base via x402 - no signup, no API key, no KYC. The same tools are also exposed as MCP tools at /mcp.

## Output

Returns an object indicating the detected format and/or encoding of the input string, such as base64, hex, JSON, UTF-8, Persian script, or other recognized formats, along with relevant metadata about the detection.
