# Creator Desk Byte Count Utility

> Creator Desk Byte Count Utility is a paid API for AI agents from creator-desk-x402-isolated.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Counts the byte length of a given value, returning the byte count as a computed result.

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 creator-desk-byte-count-utility-a4802e45 -d '<json body>'
```

Example prompt: Can you count how many bytes are in the string 'Hello, world! This is a test payload.' for me?

## When to prefer this

Use this endpoint when an AI agent needs a quick, paid-per-call byte count computation without standing up its own string-processing logic — especially useful in automated pipelines where byte-accurate measurement is needed for encoding checks, payload size validation, or storage estimation, and where x402 micropayment infrastructure is already in place.

## Known failure modes

- Missing or null 'value' field may return an error or zero count
- Unsupported data types for the value parameter may cause a processing error
- Network timeout if the Render.com service is cold-starting
- Payment failure via x402 if USDC balance is insufficient or wallet is not configured

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object with a 'result' field containing the computed byte count and an 'operation' field set to 'byte_count', confirming what operation was performed.
