API
API: documented, not servedLas herramientas de este sitio se ejecutan en tu navegador y mantienen tus datos en tu dispositivo. Para la automatización —scripts, pipelines e integraciones—, los mismos cálculos deterministas están disponibles como una pequeña API HTTP. Es el equivalente programático de las herramientas del navegador, no un reemplazo de ellas.
Why the API is documented but not served here
Running a public API means paying for compute on every call, with a bill that grows with usage in ways a single maintainer cannot cap safely. This site is deliberately free and predictable to run, so it serves the browser tools (which compute on your own device, at no cost to the host) and keeps the API dormant rather than risk unbounded cost. The endpoints are real and the contract is stable; what is switched off is the hosted execution. If you need the API today, the engine is open and can be run yourself.
Self-hosting: turn the toolbox into your API
Everything needed to consume these tools as an Application Programming Interface (API) ships in the open-source repository, and the path from download to serving is deliberately short. One: download the source - github.com/ronutz/arsenal, Apache-2.0 licensed. Two: switch the API on - open src/config/apiSurface.ts and flip the single API_PROCESSING switch from 0 to 1; that one value drives both the Worker that serves the endpoints and every API badge in this interface, so the two can never disagree. Three: compile and deploy - npm install, npm run build, and publish to your own Cloudflare Workers account with the adapter already wired into the repository. Four: call the endpoints documented in the reference below - now answered by your deployment, on your domain, under your control.
That is the whole design: self-hosting plus a flip of a switch makes this an API toolbox. The same deterministic engines that power these pages answer the endpoints - tools that compute, never guess - and the switch works in both directions: set API_PROCESSING back to 0, redeploy, and the surface returns to documented-but-not-served, endpoints answering 404, badges neutral.
Qué significa esto para tus datos
La API recibe únicamente la entrada que le envías, calcula un resultado y lo devuelve. No tiene estado y no registra valores de consulta ni cuerpos de petición. Si necesitas cero salida de datos garantizada, usa las herramientas del navegador o ejecuta tú mismo el motor abierto.
El mismo motor que el navegador
Cada endpoint ejecuta la misma función pura que la herramienta en el navegador, de modo que la API y el navegador devuelven resultados idénticos byte a byte.
