Add Website Cost Data to Resources > APIs

[VrumVrum]

Adds one entry to Resources > APIs (alphabetical position, matches existing format).

Website Cost Data — https://projectcostestimator.com/api-docs
JSON benchmarks for web-project costs (build cost, hosting, 3-year TCO, hourly-rate ranges) by platform (WordPress, Shopify, WooCommerce, Magento, custom) and geographic market. Licensed CC BY 4.0.

Against the contribution notes:

• Browser-based: yes — docs page + a plain JSON endpoint (/api/cost-data), nothing to install
• Direct link: yes — goes straight to the API docs
• 100% free: yes — no signup, no key, no usage limits; verified before submitting (HTTPS 200, Access-Control-Allow-Origin: *, no auth)

Disclosure: I built this API/dataset.

Hey VrumVrum! Thanks for your submission! 🚀

To keep awesome-devtools instantly accessible for everyone, all tools must be:

• Browser-based — no downloads or native app installs
• Direct link — goes straight to the tool (not a multi-tool landing page)
• 100% free — no signups, trials, paywalls, or usage limits

Please make sure your PR meets these criteria. It may take some time for your submission to be reviewed — you can occasionally comment with a "bump" to bring more attention to it.

Thanks for contributing! 🙌
