FLEXIBLE RPCS THAT ADJUST TO YOUR TRAFFIC

Cardano infrastructure that scales with your dApp.

Managed Ogmios, Kupo, Blockfrost RYO and UTxO RPC on mainnet, preprod and preview. Serverless and multi-tenant: you pay per request, reserve throughput when you need it, and $0 when nothing is calling.

No infrastructure to provision · open-source ports · endpoints stay the same at every tier

01 — ZERO OPS

Forget about infra

Monitoring, security patches, version upgrades — handled. You ship the dApp; we keep the machinery invisible.

02 — SCALES TO ZERO

Pay for requests, not servers

Load-balanced instances appear when traffic spikes and disappear when it doesn't. Idle costs exactly $0.

03 — MULTI-REGION

99.9% SLA, measured publicly

Active-active redundancy across availability zones in every region. Our status page does the bragging.

FOUR APIS · ONE PLATFORM

Choose your own API

WebSockets, HTTP, REST or gRPC — pick the API that fits how you already build. Ogmios, Kupo, Blockfrost and UTxO RPC all run on the same multi-region backbone, so the choice is yours to change later.

// ogmios over websocket — mainnet
const ws = new WebSocket(
"wss://mainnet-v6.ogmios-m1.demeter.run"
);
ws.send(JSON.stringify({ method: "queryNetwork/tip" }));
// → responds in 38ms, from the nearest region

Open source, top to bottom

NO VENDOR LOCK-IN · RUN IT YOURSELF ANY TIMEREAD THE DOCS →

Every API we host is open-source software with a public spec — the same binaries you can run on your own laptop. We operate them; we don't own them. If you ever want to leave, point your client at your own node and nothing in your code changes.

OPERATED BY EXPERTS

Multiple operators. Zero single points of failure.

Demeter is run jointly by TxPipe and Blink Labs — two independent engineering teams you already know from the Cardano ecosystem. Each runs a full, idempotent copy of the stack behind a health-checked load balancer: either provider can serve any request, so if one operator is out, your traffic never notices.

RUN THE NETWORK

Become a Demeter operator

Run a copy of the stack in your own region and serve traffic alongside TxPipe and Blink Labs. Open extensions, shared on-call, revenue on the requests you serve.

PRICING

Pay for what you use. Nothing when idle.

Usage is metered per port and scales to zero. You only pay a minimum fee once you reserve throughput.
