# Myworker Agent API – util-kotak Utility Box

> Myworker Agent API – util-kotak Utility Box is a paid API for AI agents from crypto-micro-agent.mykira.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-23).

Provides a collection of common utility operations: Base64 encode/decode, SHA-256 hashing, UUID generation, current timestamp, and public holiday lookups by country and year.

## Facts

- Endpoint: GET https://crypto-micro-agent.mykira.workers.dev/api/agent/util-kotak?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-23

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 myworker-agent-api-util-kotak-utility-box-64f7d734
```

Example prompt: Can you SHA-256 hash the text 'hello world' for me using the util-kotak utility service?

## When to prefer this

Choose this endpoint when you need lightweight, stateless utility computations — especially SHA-256 hashing, Base64 encoding/decoding, UUID generation, or public holiday lookups — and you are already operating in a pay-per-call x402 micropayment context on Solana or Base. It is particularly convenient when you need multiple utility types from a single API rather than integrating separate libraries.

## Known failure modes

- Missing required 'op' query parameter — returns error response
- Invalid 'op' value not in enum — returns error
- Missing 'text' for encode64/decode64/sha256 operations — returns error
- Invalid country code — may return empty or error
- Payment not fulfilled (x402) — HTTP 402 returned before result is delivered

## How this service works

Servis berbayar untuk bot/agen (x402): data pasaran Solana via Jupiter + RPC, dan servis AI via Workers AI. Bayar per panggilan dengan USDC di Solana, USDC di Base, atau SOL.

## Output

Returns a JSON object with ok:true, the operation name, and the computed result — e.g. for SHA-256: the hex digest and byte length; for encode64/decode64: the encoded/decoded string; for uuid: a new UUID; for masa: the current timestamp; for cuti: a list of public holidays for the given country and year.
