# Delx Commerce — URL Tracking Parameter Strip

> Delx Commerce — URL Tracking Parameter Strip is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Removes specified tracking parameters (e.g. UTM, gclid) from a URL, returning a clean URL without retaining input data

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 delx-commerce-url-tracking-parameter-strip-70d411c3 -d '<json body>'
```

Example prompt: Strip the UTM and gclid tracking parameters from this URL: https://example.com/page?id=7&gclid=abc123&utm_source=google&utm_medium=cpc — remove utm_source, utm_medium, and gclid but keep the rest.

## When to prefer this

Prefer this endpoint when you need a lightweight, pay-per-call, no-signup solution to programmatically strip known tracking parameters from URLs — especially in agent pipelines where privacy, verifiability (SHA-256 evidence), and zero data retention are required. It is ideal for processing individual URLs in real time. For bulk or batch URL cleaning pipelines, consider whether a self-hosted regex solution or a higher-volume service is more cost-effective.

## Known failure modes

- Malformed or non-URL string input may result in a processing error or pass-through without stripping
- If none of the specified parameters exist in the URL, the result URL equals the input URL and removed_parameters is empty
- Exceeding the 8192-character URL limit or 256-parameter array limit will cause a validation error
- Payment failure over x402 (insufficient USDC balance) will block the request before processing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the cleaned URL (with specified tracking parameters removed) and a list of the parameters that were actually removed. Also includes an evidence block confirming no external calls were made, no data was retained, and providing a SHA-256 hash of the input for verifiability.
