Protect your API, your data and your free tier
Stop scrapers copying your data, competitors reselling your results and bots draining free-tier resources, across your app and API.
What you're up against
Scraping proprietary data
Competitors and AI-training crawlers copy the content, results and prices that make your product valuable.
Free-tier abuse
Automated signups and scripted use turn your free tier into someone else's back end, and your infrastructure bill pays for it.
API abuse
Scrapers skip your interface and call the endpoints behind it directly, where a form widget never sees them.
AI agents, wanted and unwanted
Customers increasingly send AI agents to use your product. Blocking all automation turns them away; allowing all of it lets abuse in.
How Prosopo stops it
- Detection that doesn't depend on request rate
- A scraper running one search every few seconds from a home IP looks normal on volume. Prosopo spots it by an environment that doesn't hold together, which slowing down can't fix.
- Your API covered, not just your forms
- Prosopo Protect checks every request to your app and JSON API at your edge, with clean status codes for API clients.
- Patterns become standing rules
- Once an attacker's pattern is established, it is turned into rules on the networks the traffic comes from, so blocking it again is cheap and follows them when they move.
- Let the right agents in
- Choose whether verified AI agents are allowed, challenged or blocked across your account, so the agents your customers use aren't caught by accident.

A short call with an engineer reviews what's reaching your site, where your current setup leaves gaps, and how an evaluation would be judged. Nothing to install first.

Can Prosopo stop a competitor scraping our free tier?
Will it block AI agents our customers use?
Only if you want it to. You choose whether verified AI agents are allowed, challenged or blocked, as a setting across your account.
Do we have to change our API clients?
No. Protect runs in front of your API at the edge. Requests it blocks get a status code and a header your clients can handle; everything else passes through unchanged.
