One API for the Tool Swim catalog
Automate QR, image, document, data, text, media, and web workflows through one consistent developer surface.
A consistent contract across every tool
Build once around scoped credentials, versioned endpoints, idempotent requests, stable errors, and transparent usage. Each tool documents its inputs, outputs, limits, credit cost, and availability through the same developer contract.
Scoped credentials
Create a key inside your workspace, grant the tools:execute scope, and send it as a Bearer credential. Raw secrets are shown once and must stay out of URLs, browser bundles, logs, and source control.
Idempotent execution
Every billable POST requires an idempotency key. Repeating the same request with the same key returns the deterministic result without a second charge; changing the request produces a conflict.
Transparent usage
Every operation documents its credit cost before execution. Failed validation and platform errors settle zero credits, while rate-limit and remaining-capacity headers make automation predictable.
QR Code API
POST JSON to /api/v1/tools/qr-code-generator/execute. URL, Wi-Fi, vCard, email, SMS, WhatsApp, phone, location, event, and Google review payloads are supported.
API catalog
The catalog covers four practical tool families through a consistent developer contract, with quality, privacy, performance, security, and transparent API economics built into every operation.
Images and documents
Image resizer, format converter, background remover, cropper, EXIF remover, SVG optimizer, PDF compressor, PDF merger, PDF splitter, and image-to-PDF.
Developer and data
JSON formatter and validator, Base64 and URL encoders and decoders, UUID and hash generators, timestamp converter, regex tester, diff checker, JWT decoder, and Markdown previewer.
Text and content
Word and character counter, case converter, whitespace cleaner, duplicate-line remover, slug and Lorem Ipsum generators, reading-time calculator, text comparer, HTML entity converter, and CSV/JSON converter.
Media and web
Audio and video compressors, favicon generator, color picker, contrast checker, gradient generator, screenshot cropper, meme canvas, aspect-ratio calculator, and responsive image generator.
Build with the API catalog
Use the free browser catalog when a person is completing a task. Use the API when your application needs repeatable, authenticated execution, and choose the documented endpoint for each workflow.
API request content is transmitted to Tool Swim under the documented privacy and retention boundary. Public browser tools never call this endpoint and continue to work without an account.
