Unlimited Proxy API
You set up an unlimited proxy api by removing rate caps on your routing service. Then you link your client apps to that open endpoint with shared keys. Teams often build this setup to let internal tools send fast traffic without volume blocks. Still, open routing rules and broad keys create major blind spots when apps query live data.

You set up an unlimited proxy api by removing rate caps on your routing service. Then you link your client apps to that open endpoint with shared keys. Teams often build this setup to let internal tools send fast traffic without volume blocks. Still, open routing rules and broad keys create major blind spots when apps query live data.
How an unlimited proxy api works in practice
In a standard setup, a team deploys a routing server between apps and backend services. Admins turn off quota limits so scripts and workers can send requests at any speed. Next, the team makes an access key or role for the calling app. The app sends every request through the routing server to reach databases or internal services.
The routing server checks the key on the way in. If the key matches a valid role, the server forwards the traffic to the backend. It does not slow down the app or count the number of daily calls. This design helps data pipelines and test suites run fast without hitting quota walls. Engineers do not need to ask admins to raise limits during heavy traffic spikes.
What native routing solves and where it falls short
Native routing rules solve the problem of blocked traffic during busy work hours. They also let teams use one network path for many backend services. Network admins only need to open one firewall path for the routing server. This keeps network charts simple and cuts down on support tickets for rate blocks.
Yet this native setup only checks who logs in at the start of a session. It does not check what individual statements, commands, or requests do in flight. Once an app or user passes the first key check, every call goes straight through. An engineer or script with a valid key can run broad queries or pull huge tables. If a response holds emails, phone numbers, card numbers, or national IDs, everything flows back untouched.

Why teams need request controls and field masking
High volume endpoints carry high risk when every query runs without a second check. A single bad script can drop a table or pull millions of private rows in seconds. Standard server logs only show network paths and timestamps, not the exact queries or commands. Security teams cannot tell which person ran a risky command through a shared app key.
To fix this gap, teams need controls that inspect requests and results in real time. Good controls tie every single request to a real user identity rather than a shared key. They also let admins require quick peer approval before a risky command can run. Finally, data masking rewrites matched fields like emails or card numbers in results before returning them.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What happens when an open API uses a shared key?
Every person and script using that key looks the same in your server logs. You cannot tie a bad query or data export to one specific team member.
Does removing rate limits increase data exposure risks?
Yes, removing rate limits lets a script or attacker pull huge amounts of data fast. Adding field masking and query checks stops raw sensitive fields from leaving the backend.
How can teams protect sensitive fields on high volume endpoints?
Teams can apply masking rules that rewrite emails, phone numbers, and card numbers in transit. This keeps fast traffic flowing while hiding private details in the returned results.
