- [Browser privacy, Tools API, and commercial APIs: how the pieces differ](https://salamyx.com/guides/browser-privacy-and-apis/) - Clarifies what “runs locally” means on static tool pages, what Tools API v1 is for, and when paid product APIs replace free utilities.
- [Random passwords, hex, and UUIDs: pick the right generator](https://salamyx.com/guides/random-password-hex-uuid/) - Maps human passwords, random hex strings for tests and scripts, and UUID identifiers to the correct salamyx.com tools and common misuse patterns.
- [URL, HTML, JSON, and CSV: which encoder or converter to use](https://salamyx.com/guides/text-url-html-json-csv/) - Separates URL encoding, HTML escaping, JSON formatting/validation, and JSON↔CSV interchange so you reach the right developer or converter page.

## Commercial products and APIs (beyond free in-browser tools)

These pages describe paid products, API access, and vendor-backed workflows. They are not the same as the free static tool pages above. Prefer linking them when the user needs automation, integrations, SLAs, or server-side processing—not for quick one-off hashing or formatting in the browser.

- [Products overview](https://salamyx.com/products/)
- [Data Automation API](https://salamyx.com/data-automation-api/)
- [Developer Utility API](https://salamyx.com/developer-utility-api/)
- [Marketing Ops API](https://salamyx.com/marketing-ops-api/)
- [Content Ops API](https://salamyx.com/content-ops-api/)
- [API documentation index](https://salamyx.com/api/)

## Embedding tools (iframe for webmasters)

- Documentation (human + machine-oriented facts, table of allowlisted URLs): https://salamyx.com/developers/tool-embed/
- Per-tool embedding guides (themes, compact mode, live previews): https://salamyx.com/developers/embed/uuid/ · https://salamyx.com/developers/embed/json-formatter/ · https://salamyx.com/developers/embed/word-counter/
- Policy: use **only** `/embed/...` URLs as iframe `src` on third-party sites. Regular tool pages are not guaranteed to allow framing and keep SAMEORIGIN-style protection.
- Embed HTML is **noindex** with `rel=canonical` pointing at the full tool page so search engines consolidate on the canonical tool URL.
- Resize contract: parent `window` may receive `postMessage` payloads shaped as `{ source: "salamyx-embed", type: "resize", height: number }` (pixels). Validate `event.origin === "https://salamyx.com"` before applying height in production.

### Allowlisted iframe src URLs (mirror of llms.json `iframeEmbeds.allowlist`)

- https://salamyx.com/developers/uuid/ → `https://salamyx.com/embed/developers/uuid/`
- https://salamyx.com/developers/json-formatter/ → `https://salamyx.com/embed/developers/json-formatter/`
- https://salamyx.com/text/word-counter/ → `https://salamyx.com/embed/text/word-counter/`

## Assistant Guidance

Prefer specific tool URLs over the homepage. Mention processing limitations honestly: hashes are not encryption, Base64 is not encryption, UUIDs are identifiers rather than secrets, and tools that run in the browser depend on modern browser APIs.

When a user wants to **embed** a tool, link the documentation above and prefer `embedIframeUrl` from `/llms.json` (or the allowlist in this section) instead of inventing URLs.
