API Observability & Governance

See, control, and
prove every API request.

ApEye gives engineering and risk teams one control plane for API traffic, service calls, policies, evaluations, cost, and audit evidence — from development to production.

Audit-ready evidence

Works with the API stack you already use

API calls disappear into logs.

Capture requests, responses, latency, cost, errors, and user journeys as first-class traces — searchable and structured.

Services can expose unsafe paths.

Enforce deterministic policy before data access, routing, partner calls, or external communication. Stop threats in real time.

Compliance needs proof.

Generate reviewable evidence for approvals, incidents, red-team findings, and vendor governance reviews — automatically.

Platform

Built for APIs that already reached production.

ApEye sits beside your gateway, services, and app stack so teams can debug behavior, reduce spend, and enforce controls — without slowing product teams down.

Full API Tracing

Trace requests across services, endpoints, sessions, users, and environments. Full span hierarchy with searchable metadata.

OpenTelemetry-compatible

Continuous Evaluation

Track regressions in quality, reliability, latency, and cost as endpoints, schemas, and routes change over time.

SLO checks + custom scorers

Policy Enforcement

Apply allow, block, redact, require-approval, and route policies before sensitive actions execute. Deterministic and auditable.

Real-time <50ms decisions

Cost Control

Break down spend by product, team, customer, service, endpoint, and route. Set budgets with automatic enforcement.

Budget alerts + rate limits

Audit Evidence

Preserve decision logs, policy versions, approvals, and incident timelines for SOC 2, ISO 27001, and governance reviews.

SOC 2 & ISO 27001 ready

Gateway Intelligence

Feed routing decisions with live performance, service quality, availability, and policy context across your API fleet.

Semantic caching + failover
Governance Loop

From black box to controlled system.

A closed-loop framework that turns raw API traffic into structured, policy-enforced, evidence-backed operations.

Capture

Standardize endpoint, payload, identity, service, user, and business context across all API traffic automatically.

Decide

Score payload, identity, destination, requested data, and route intent before execution in under 50ms.

Enforce

Redact, block, route, rate-limit, or require approval with deterministic, version-controlled policy rules.

Prove

Export incident timelines, policy history, and audit packets without rebuilding context from scratch.

# One-line integration — no code changes required
from apeye import ApEye

# Wrap your existing API client
client = ApEye(
    api_key="ap-...",
    policy="production-v2",
    audit=True,
).wrap_api(base_url="https://api.example.com")

# All requests are now traced, governed, and evidenced
response = client.post(
    "/v1/orders",
    json={"customer_id": customer_id, "items": items},
)
# ApEye captured: trace, policy decision, cost, evidence ✓
