In the age of AI agents,
API traffic control is essential
Blocking requests when volume spikes is no longer enough.
AI-native architectures are changing how traffic has to be managed.
NetFUNNEL API queues requests that exceed capacity instead of dropping them, then works through the queue by available capacity and priority.
Conventional traffic control
cannot handle AI agents
A single request fans out into hundreds of internal calls, and response times swing from milliseconds to minutes. RPS-centric rate limiting is already showing its limits.
LLM agent traffic
- AI agents calling other AI agents in chains
- One request → hundreds of internal calls
Unpredictable processing time
- Response times that jump from milliseconds to minutes
- Traditional rate limiting can't keep up
Token-based cost structure
- Traffic control by TPM, not RPS
- Context size drives infrastructure cost
One request can fan out into hundreds —
keep API traffic flowing
One slow response from an external LLM can cascade through chained AI-agent calls and stall your whole backend.
NetFUNNEL API admits server-to-server requests at the rate your system can handle, so overload never gets that far.
Control based on live resource metrics,
not static limits
Fixed rate limits use resources inefficiently and fail to reflect the server's real state. NetFUNNEL watches CPU, memory, response time, and tokens in real time to adjust the flow dynamically.
Limitations of traditional rate limiting
Static thresholds waste capacity, ignore what the server is actually doing, and need retuning every time the environment changes.
- Fixed values → resource inefficiency
- Real server state ignored
- Manual tuning on every change
How NetFUNNEL solves it
It adjusts to live server metrics: bypass under normal load, automatic filtering only when load climbs.
- Real-time resource-based control
- Bypass normally → auto-filter under load
- Based on AI API tokens and response time
Keep critical APIs available —
even under load
When traffic surges, you cannot handle every request equally. By assigning priority per URI, header, and tier, we protect the availability of critical APIs and VIP traffic first.
Control every traffic flow from one screen
One console shows every request state in real time: total, completed, queued, and blocked.
When something looks off, you act from the same screen.
Without manual intervention,
the system adjusts on its own
It watches system resource metrics,
turns the queue on the moment a threshold is crossed,
and resumes normal processing as load eases.
Nobody has to touch the thresholds.
Even when AI responses slow down,
the service never stops
A two-second delay from an external LLM can leave every internal server blocked.
NetFUNNEL API cuts admissions the moment response times rise, then opens back up once they recover.
Frequently Asked Questions
Common questions before getting started. Reach out anytime to learn more.
NetFUNNEL API is an API traffic-control solution that, instead of immediately rejecting API requests beyond the system's processing capacity, holds them in a queue and processes them sequentially according to available capacity and configured policies. If current throughput is within the configured admission rate, requests are processed immediately; a waiting policy applies only when processing capacity is exceeded. This reduces the loss of legitimate API requests during traffic surges and prevents backend overload.
The fastest way to try it.
Test and deploy the way you want, with no changes to your service environment.
