Every tool on UtilityApps, available as an API endpoint. 107 tools today; the same engines, callable from your backend, with sensible auth and per-key rate limits.
A rough sketch of the surface area.
PDF endpoints
Merge, split, rotate, watermark, compress, sign — what the in-browser PDF tools do, callable from your backend.
Image endpoints
Compress, resize, convert, watermark, remove background — wired to the same engines as the web tools.
Document generation
Privacy policies, terms of service, NDAs, freelance contracts — generate to PDF / Word via a single POST.
Sharing + shortener
Programmatic link shortening + text/file share. Same auto-expiry, password, view-limit options as the UI tool.
Office conversions
Word ↔ PDF, Excel ↔ PDF, PowerPoint ↔ PDF. Wraps ConvertAPI so you don't have to.
Webhooks
Get notified when long-running jobs finish — fire-and-forget conversions, scheduled shares, etc.
Shipping a public API isn’t just the endpoints. It’s API keys, per-key rate limits, billing, usage dashboards, SLAs, error budgets, and a docs site that doesn’t go stale. That’s weeks of work before the first paying call comes through.
So we’re validating demand first.If 100+ developers sign up on this page, we’ll start building. If 10 sign up, we’ll build something else and come back to this when the market signals louder.
Drop your email + a sentence on what you’d use it for. The use-case description is what helps us decide which endpoints to ship first — and which ones we can skip.
API keys
Generate / revoke from a dashboard. Scoped to specific endpoints if you want.
Free tier
A useful daily quota at $0 — enough to evaluate the API in your prod-adjacent staging.
Predictable pricing
Per-call pricing, no surprises. The same conversion that costs $0.01 today will cost $0.01 next year.
