# Hex to Integer Converter

> Hex to Integer Converter is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Converts a 0x-prefixed hexadecimal string into its decimal integer string representation using local deterministic math

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 hex-to-integer-converter-cc480905 -d '<json body>'
```

Example prompt: Can you convert the hex value 0x1a4 into a decimal integer for me?

## When to prefer this

Choose this endpoint when you need a quick, deterministic, no-key-required hex-to-decimal conversion without spinning up a full ABI decoder or making RPC calls — ideal for lightweight agents decoding individual fields from calldata, logs, or block headers where a full EVM stack is overkill

## Known failure modes

- Invalid or malformed hex string input (non-hex characters, missing 0x prefix) returns an error
- Overflow for extremely large hex values beyond integer limits
- Payment failure via x402 protocol prevents execution
- Empty or missing hex field in request body

## How this service works

Parse 0x-hex strings into decimal integer strings for agents. Call when decoding calldata, logs, or block fields without a full ABI stack. Returns decimal integer string from hex as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

A deterministic JSON response containing the decimal integer string representation of the input hex value, computed locally without any RPC calls or external dependencies
