One API. One bill.
Every provider.

FlexYield routes your JSON-RPC traffic across multiple upstream providers with automatic failover — one key, one invoice, at prices below going direct. No wallet, no crypto required.

Try it live — no signup

Pick a chain and a method, hit send — the request goes through the real gateway: same relay, same automatic failover, same upstreams. You'll see the response time and which provider actually served you.

Demo methods only — sign up free for the full JSON-RPC surface with your own key. Full reference in the docs.

The problem

Web3 infrastructure is a vendor-juggling act.

Going direct

Every chain and every workload means another provider: separate keys, separate dashboards, separate invoices — and when your provider goes down, so do you.

  • A key and a bill per vendor
  • No failover when one provider fails
  • Retail pricing on every contract
  • Hours lost comparing and migrating

One API through FlexYield

Point your app at a single endpoint. We route every request to the best healthy upstream, fail over automatically, and pass wholesale savings on.

  • One key, one bill across providers
  • Automatic multi-provider failover
  • Wholesale rates passed on to you
  • Live volume, latency and spend per key

How it works · three steps to one bill

Create your key

Sign up with an email address and get an API key in under a minute. Free tier included — no wallet, no sales call.

Point your app at one endpoint

Swap your provider URL for ours. Standard JSON-RPC 2.0 — no SDK, no code changes beyond the URL.

curl -X POST https://flexyield.io/rpc/eth_mainnet \
  -H "Authorization: Bearer $FLEXYIELD_KEY" \
  -d '{"jsonrpc":"2.0","id":1,
       "method":"eth_blockNumber","params":[]}'

We route, you watch

Every request goes to the best healthy upstream with automatic failover. Track volume, latency and spend live in your dashboard.

Vision

The long view

Built for what comes next

The gateway generates real revenue today. It is also the foundation for something much larger.

Every service we add makes one interface more useful — and, over time, that interface can reach far beyond RPC. Our long-term direction is to make FlexYield the single place to source any kind of decentralized infrastructure: not only RPC, but oracles, bridging, compute, storage, bandwidth and beyond. One account. One bill. Every provider.

For humans

One dashboard, zero integration hell

Developers and teams source everything they need from a single, unified interface — no juggling a dozen providers, APIs and invoices.

For bots

On-demand capacity at machine speed

Trading and automation systems tap dedicated, low-latency infrastructure the instant they need it, and pay only for what they use.

For agents

Infrastructure that settles itself

Autonomous agents discover, provision and settle for infrastructure entirely in code — a market designed for software that acts on its own. Full MCP support today.

Revenue comes first — every expansion is funded by the service before it. The bigger picture is simply where that leads.

Early access

Get on the list.

The RPC gateway is live and free to try today. The waitlist is for what's next: new capabilities, new chains, and founding-customer pricing windows. Tell us who you are so we build the right thing first.

Run infrastructure? Sell through us.

FlexYield buys capacity wholesale and routes real demand to providers that stay healthy. One integration, metered payouts.
