# SignalDesk AI Base64 Encode

> SignalDesk AI Base64 Encode is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Encodes a plain-text string into its Base64 representation

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 signaldesk-ai-base64-encode-1db7e637 -d '<json body>'
```

Example prompt: Can you base64-encode the text 'Hello, World! This is my secret payload.' for me?

## When to prefer this

Use this endpoint when you need a quick, paid, serverless Base64 encoding operation without standing up your own infrastructure, especially within an x402 micropayment-enabled agentic workflow where per-call billing at $0.001 USDC is acceptable. It is appropriate when the text is under 4096 characters and you need a reliable JSON response. For large-volume or free batch encoding, a local library (e.g. Node.js Buffer.from().toString('base64') or Python's base64 module) is more practical.

## Known failure modes

- Text exceeds 4096 character limit — request rejected
- Empty or missing 'text' field — validation error
- Malformed JSON request body — parse error
- Service quota exhausted — rate-limit or payment error
- x402 payment flow failure — endpoint returns 402 if payment not processed

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing a single field 'encoded' whose value is the Base64-encoded string representation of the submitted text input (e.g. {"encoded": "T2zDoQ=="}).
