# AgentShelf URL Redaction

> AgentShelf URL Redaction is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

## 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 agentshelf-url-redaction-e9795fac -d '<json body>'
```

Example prompt: Redact all URLs from this text before I store it: 'Check out our new site at https://example.com and also visit http://promo.example.org/sale for deals!'

## When to prefer this

Choose this endpoint when you need a lightweight, stateless, privacy-respecting service to strip URLs from arbitrary text without storing any data. Prefer the free sandbox endpoint POST /v1/sandbox/redact-url first for testing; use this paid endpoint ($0.01 USDC) for production workloads or when the sandbox is unavailable.

## Known failure modes

- Empty or missing 'text' field returns a 400 validation error
- Text exceeding 100,000 characters is rejected
- Payment failure (x402) if USDC payment is not properly attached
- Network timeout if the request takes too long

## How this service works

Call when an agent needs url matches redacted in text. Nothing is stored. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/redact-url first.

## Output

Returns the input text with all URL occurrences replaced or removed (redacted), leaving the surrounding text intact. No data is stored server-side.
