API INFRASTRUCTURE

Route, secure, and monitor every API your team ships.

One dashboard for gateways, keys, rate limits, and traffic — so your team spends less time gluing infrastructure together and more time shipping.

WHAT RELAY_ DOES

Everything between your service and the internet.

Three things you need for any production API, built to work together instead of bolted on separately.

Routing & gateways
Put every API behind one edge — custom domains, versioned endpoints, and zero-downtime cutovers.
  • ›Custom domains with managed SSL
  • ›Per-endpoint rate limits
  • ›Blue/green deploys
Auth & policy
Scope keys per environment, enforce CORS and IP allowlists, and roll a leaked key without a deploy.
  • ›Environment-scoped API keys
  • ›CORS & IP allowlist policies
  • ›Instant key rotation
Observability
Every request logged with full headers, body, and timing — searchable the moment it happens.
  • ›Full request/response logs
  • ›Per-endpoint latency & error rate
  • ›Threshold alerts to Slack/webhook
BUILT FOR HOW YOU SHIP

One request to get a production-grade endpoint.

$ curl https://api.acme.relay.sh/v1/users \ -H "Authorization: Bearer sk_live_9f2a...c81" { "status": 200, "latency_ms": 38, "region": "iad1", "data": [ … ] }
Connect your existing service
Point a route at your origin — no SDK, no code changes on your service.
Get a scoped key in seconds
Keys are environment-scoped from the start, so staging traffic can never touch production.
Watch it in the request log
Every call — headers, body, response, latency — searchable the moment it lands.
