Zuplo API Gateway
Provides a fully managed, OpenAPI-native API gateway with programmable request/response handlers, rate limiting, API key management, and an auto-generated developer portal deployed at the edge.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API keys are hashed at rest. JWT validation supports JWKS endpoints. OAuth2 integration with major IdPs. All traffic terminates TLS at the edge. Secret environment variables available for handler code.
⚡ Reliability
Best When
You want a managed, code-friendly API gateway that deploys from an OpenAPI spec with minimal DevOps overhead and includes a built-in developer portal.
Avoid When
You need self-hosted deployment, multi-region active-active routing with custom SLAs, or an open-source solution with no vendor lock-in.
Use Cases
- • Deploy an agent-facing API gateway in front of backend services in minutes using an OpenAPI spec without managing infrastructure
- • Issue and revoke API keys for agent consumers programmatically via the Zuplo management API with per-key rate limits
- • Add custom TypeScript handler logic at the edge to transform requests or inject auth headers before they reach agent backends
- • Auto-generate a developer portal from OpenAPI spec so other agents or developers can discover and test your API
- • Enforce per-consumer rate limits and quotas at the gateway layer without modifying backend agent code
Not For
- • Self-hosted or on-premises API gateway deployments where you own the infrastructure (use Kong or Tyk)
- • Complex service mesh traffic management between internal microservices (use Istio or Envoy)
- • Realtime WebSocket pub/sub messaging (use Ably or Pusher)
Interface
Authentication
Supports API key auth, JWT validation, and OAuth2 with multiple identity providers. API keys are managed as first-class resources with metadata and per-key rate limit overrides. Gateway-level auth is configured via policy YAML per route.
Pricing
Free tier supports one project — suitable for a single agent API. Paid tiers unlock multiple projects, higher request volumes, and SLA guarantees.
Agent Metadata
Known Gotchas
- ⚠ Gateway logic is written in TypeScript/JavaScript — agents generating gateway handler code must produce valid TypeScript that passes Zuplo's deployment validation
- ⚠ Configuration changes (routes, policies) are deployed as a new version; there is no hot-reload — agents must account for deployment latency when making gateway changes
- ⚠ API key metadata is stored as arbitrary JSON but has a size limit; agents storing rich per-key context must keep payloads small
- ⚠ The free tier limits to one project; agents managing multiple environments (dev/staging/prod) need a paid plan
- ⚠ Custom domains require DNS verification; agents automating full gateway provisioning must handle DNS propagation delays
