Build a CoinMarketCap price tracker in minutes

Point the recorder at a CoinMarketCap page, mark the coin price, and Writ builds a Monitor that reads it on a schedule and fires a workflow on a drop, running on your own account, on a page you are authorized to use.

  1. 1
    Open a CoinMarketCap item in the recorder

    Point the recorder at the CoinMarketCap page and mark the coin price. Writ renders CoinMarketCap in real Chromium, so it reads values that load with JavaScript, not list-price theater.

  2. 2
    Set the schedule and target

    Choose how often Writ checks (as fast as every 10s) and a target price or percentage drop. Each check records the coin price, building a real price history.

  3. 3
    Act on the drop

    A matching change fires a workflow: notify you across six providers, log the new coin price, or trigger an optional approved workflow on your own authenticated CoinMarketCap account.

CoinMarketCap price tracking questions

How does CoinMarketCap price tracking work?
Writ sets up a Monitor on the CoinMarketCap page you choose and reads the coin price in a real browser, so it catches values that load with JavaScript. It checks as fast as every 10s and records each reading, so you see a true price history and get alerted on a real change.
Is there a ready-made CoinMarketCap price tracker I can install?
Yes. Point the recorder at the CoinMarketCap page, mark the coin price, and Writ builds a Monitor that reads it on a schedule. No catalog listing required; it takes minutes.
Can it act automatically when CoinMarketCap drops to my price?
Yes. A price drop can trigger an approved workflow on your own authenticated CoinMarketCap account. It runs with guardrails on by default: a dry-run mode, a confirm gate, a rate limit, and idempotency so one detected change never triggers the action twice.
How will I be notified of a CoinMarketCap price change?
Through any of six providers (Email, SMS, WhatsApp, Signal, Pushover, or a custom webhook), or by running a full workflow that records the new coin price or pushes it to a destination.
Is it allowed to track prices on CoinMarketCap?
Collect CoinMarketCap data you have the right to access and respect its Terms of Use and rate limits. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
