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.

Made for you.

If HTTP traffic is your product, the relay is your middle layer.

You ship models

AI builders

Stream model responses through one endpoint, and let your agent configure it.

You resell APIs

API resellers

Your endpoint up front, with keys, limits and validation in the middle.

You ingest events

Webhook-heavy teams

One event in, every consumer out: retried, replayable, nothing lost.

Explore use cases

One call. Every service.

A real request, end to end. You POST once, we fan it out.
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": "…"
}

What you can build

EchoRelay is the target your callers hit and the source that calls your services. Pick a shape →
Fan-out One request, every target. Streaming Responses stream back, chunk by chunk. Mirror Send it live, keep a shadow copy. Origin shield Hide your servers behind us.

Explore relay shapes

One call in, fanned out.

You call once, we authenticate, validate, bill, and fan it out to every service. The relay runs in reverse, too.
  1. Caller
    Your app sends one request.
  2. EchoRelay
    Authenticated, validated, billed, then fanned out.
  3. Queue
    Durable queue. At-least-once, always.
  4. Delivery
    Delivered with retries; nothing lost.
  5. Your targets
    Every service you connect.

Always PROTECTED

Everything that reaches you went through us first.
  • Your servers, invisible.
    Clients connect to us, never to you. Your real infrastructure stays completely off the map.
  • Flood protection, built in.
    We stand between you and the internet. Threats hit us first. And stop there.
  • Confidential by design.
    We can't read your stored secrets. Your keys, encrypted. Bring your own, we see nothing, keep nothing.
  • Nothing slips through.
    Payloads validated against your schema. Malformed or malicious data stops here.

Built for AI.

Your agent configures EchoRelay. You ship.

One endpoint, the whole control plane.

A single MCP server (Model Context Protocol: how AI agents call tools) exposes your API versions, endpoints, targets, billing.

Drops into any agent.

Claude, ChatGPT, Cursor, OpenCode. Bearer token in, project on rails.

No forms. No clicks.

Describe the integration in plain English. Your agent writes the config.
