Clean curl commands for LLMs and AI agents

When you paste a raw DevTools curl into ChatGPT, Claude, Cursor, or another agent, you pay for every character — including User-Agent, Sec-Fetch-*, and dozens of headers the model does not need. Curl Cleaner shrinks the command so your prompt focuses on the actual API call.

Why browser curl commands waste tokens

A typical Chrome “Copy as cURL” export is 1,500–3,000 characters. Roughly half is browser metadata: client hints, fetch metadata, accept headers, and encoding preferences. None of that helps an LLM understand or replay your API request.

Curl Cleaner removes that noise client-side — nothing is uploaded — and shows an approximate token count before and after so you can see the savings immediately.

What to keep for agent prompts

• URL and HTTP method — the endpoint being called.
• Authorization — Bearer tokens, API keys (redact before sharing publicly).
• Content-Type — tells the agent the body format.
• Request body — JSON, form data, or GraphQL payload.
• Cookie — only if the session matters (toggle in Settings).

Workflow for coding agents

1. Reproduce the API call in your browser and copy as cURL.
2. Paste into Curl Cleaner — cleaned output appears instantly.
3. Copy the minimal curl and paste into your agent with a prompt like “convert this to a Python script” or “debug this 401”.
4. Use the token estimate in the footer to confirm you trimmed enough context.
