Infrastructure for AI Agents
Policy enforcement, kill switch, and observability for every outbound API call your agents make.
from checkrd import wrap
import httpx
client = wrap(
httpx.Client(),
agent_id="sales-agent",
policy="policy.yaml",
)
# Every request is now policy-enforced
response = client.get("https://api.salesforce.com/data")Trusted by engineers building production AI agents
Everything your agents need
A single proxy layer that handles policy, safety, and observability. One line of code to integrate.
Policy Engine
YAML-defined rules enforced at the network layer. URL patterns, method filtering, rate limits, body inspection, and time-of-day restrictions.
Kill Switch
Instantly block all outbound calls from any agent. The 3 AM safety net every engineering leader deploying agents needs.
Observability
Structured telemetry for every proxied call. Endpoint, method, status code, latency. OpenTelemetry compatible.
WASM Sandbox
233KB WebAssembly core with zero I/O access. 62 microsecond evaluation. Security is architectural, not trust-based.
Open Source
The proxy core and language wrappers are open source. No vendor lock-in. Standard HTTP proxying. pip install and go.
