# webtools.genexxis.com URL Base64 Encoder

> webtools.genexxis.com URL Base64 Encoder is a paid API for AI agents from webtools.genexxis.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-30).

Fetches a public URL (up to 5 MB) and returns its content as a base64-encoded data URI along with content type, byte size, SHA-256 hash, and final URL after redirects.

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 webtools-genexxis-com-url-base64-encoder-5445939a
```

Example prompt: Can you fetch https://upload.wikimedia.org/wikipedia/commons/thumb/4/47/PNG_transparency_demonstration_1.png/280px-PNG_transparency_demonstration_1.png and give me the base64 data URI, its SHA-256 hash, and the final URL it resolved to?

## When to prefer this

Use this endpoint when you need to fetch a remote public URL and get its content encoded as base64 (with a data URI) in a single call, especially when you also need cryptographic verification (SHA-256) or content metadata (type, size, final URL). Ideal for embedding remote resources inline, verifying file integrity, or archiving snapshots of web pages without a full scraping pipeline.

## Known failure modes

- URL exceeds 5 MB limit — request rejected
- Non-public or private URLs return an access error
- Redirect chain leads to a URL that also exceeds size limit — re-checked and rejected
- Invalid or malformed URL returns a parsing error
- Target server is unreachable or times out
- URL returns a non-200 status code (e.g. 404 or 403)

## How this service works

Downloads a public URL (max 5 MB, redirects followed and re-checked) and returns its content as base64 with a data URI prefix, content type, byte size, sha256 and final URL.

## Output

A JSON object containing: the original requested URL, the final URL after following redirects, HTTP status code, content type (MIME type), byte size of the content, the full content encoded as base64, a data URI combining content type and base64, and a SHA-256 hash of the raw content.
