- Fix hardcoded DATABASE_URL in 4 new microservices (gpu-service, governance-service, trading-service, marketplace-service) - now use os.getenv() with SQLite fallback - Move httpx.AsyncClient to API gateway lifespan for connection pooling - Add 30-second timeout to API gateway proxy calls - Move hardcoded service URLs to environment variables in API gateway (GPU_SERVICE_URL, MARKETPLACE_SERVICE_URL, etc.) - Add cli/build/ and cli/dist/ to .gitignore and remove 42 stale build artifacts from git - Fix version pinning conflicts in 4 new service pyproject.toml files (align with root: fastapi >=0.115.6, sqlmodel >=0.0.38, pytest >=9.0.3) - Fix 18 remaining datetime.utcnow() calls in monitoring-service and ai-service (replace with datetime.now(timezone.utc)) - Add retries (3 attempts), authentication (Bearer token), rate limiting (100/min via slowapi), and circuit breaker to API gateway - Add /ready and /live endpoints to 4 new microservices for production readiness/liveness probes - Audit debug logging - confirmed no sensitive data (passwords, keys, secrets, tokens) is logged; cache keys and masked API keys are safe
AITBC API Gateway
Routes requests to AITBC microservices.
Service Registry
The gateway routes requests to the following services:
- GPU Service (port 8101):
/gpu/*→ GPU resource management - Marketplace Service (port 8102):
/marketplace/*→ GPU marketplace - Agent Service (port 8103):
/agent/*→ Agent operations - Trading Service (port 8104):
/trading/*→ Trading operations - Governance Service (port 8105):
/governance/*→ Governance operations - Coordinator API (port 8000):
/coordinator/*→ Coordinator API (default)
Installation
cd /opt/aitbc
poetry install --with api-gateway
Running
# Development
python -m api_gateway.main
# Production (systemd)
sudo systemctl start api-gateway
sudo systemctl enable api-gateway
Testing
Prerequisites
- All microservices installed via Poetry
- At least one microservice running (e.g., GPU service)
- Microservice database created (if testing that service)
Start Gateway (Development)
python -m api_gateway.main
