The universal relay layer
One endpoint fans out to all your services. 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.
If HTTP traffic is your product, the relay is your middle layer.
Wrapping a model? Stream its responses through one endpoint — and let your agent configure it.
See howSelling third-party APIs as your own? Your endpoint up front — keys, limits and validation in the middle.

You call once — we authenticate, validate, bill, and fan it out to every service. The relay runs in reverse, too.
One call. Every service.
curl -X POST https://your-project.echorelay.cloud/v1/your-endpoint \
-H "Authorization: Bearer er_live_YOUR_KEY" \

-d '{"event":"order.placed","orderId":"ord_42"}'
# EchoRelay validates, queues, fans out, retries — you get:
HTTP/1.1 202 Accepted
{
"status": "queued",
"requestId": "…"
}Your agent configures EchoRelay. You ship.
A single MCP server (Model Context Protocol — how AI agents call tools) exposes your API versions, endpoints, targets, billing.

Describe the integration in plain English. Your agent writes the config.
Your agent does this:
