# IPIntel.ai Base64 Decode API

> IPIntel.ai Base64 Decode API is a paid API for AI agents from tools.ipintel.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Decodes a Base64-encoded string (including URL-safe variants) and returns the decoded text, hex representation, UTF-8 validity, and metadata.

## Facts

- Endpoint: POST https://tools.ipintel.ai/base64-decode
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 ipintel-ai-base64-decode-api-c7291e5c -d '<json body>'
```

Example prompt: Can you decode this Base64 string for me and tell me if it's valid UTF-8: 'aGVsbG8gd29ybGQ='?

## When to prefer this

Use this endpoint when you need to decode a Base64 string programmatically in an agent workflow, especially when you also need metadata like UTF-8 validity, hex output, or URL-safe detection — and when pay-per-call micropayment pricing via x402 fits your usage pattern.

## Known failure modes

- Invalid or malformed Base64 input returns ok:false or valid:false
- Non-UTF-8 binary data sets is_utf8:false but still returns decoded_hex
- Payment failure via x402 protocol returns 402 status before processing
- Empty input may return an error or zero-length decoded output

## How this service works

Base64 Decode API. Decode standard or URL-safe Base64 and return UTF-8 text when possible, hex output, validity, and output length. Useful for agents, developers, token inspection, API debugging, decoding workflows, data transformation, and automation tasks. Paid per call via x402.

## Output

Returns a JSON object with: ok/valid boolean flags, the decoded plain-text string, its hex representation, whether it is valid UTF-8, whether the input was URL-safe Base64, the output byte length, and a timestamp.
