The universal relay
We carry the traffic. You ship.
The layer between your callers and every service: gateway, webhook broker, and AI-agent tool in one.
No credit card required.
You ship models
Stream model responses through one endpoint, and let your agent configure it.
You resell APIs
Your endpoint up front, with keys, limits and validation in the middle.
You ingest events
One event in, every consumer out: retried, replayable, nothing lost.
curl -X POST https://your-project.echorelay.cloud/v1/your-endpoint \
-H "Authorization: Bearer er_live_YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{"event":"order.placed","orderId":"ord_42"}'
