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"}'

# EchoRelay validates, queues, fans out, retries. You get:
HTTP/1.1 202 Accepted
{
  "status": "queued",
  "requestId": "…"
}
```
