About FREERPC.com

FREERPC.com provides free, rate-limited RPC access to major blockchain networks so anyone can prototype, learn, and build without a credit card or signup wall.

The service is operated by Tatum, using the same infrastructure that powers enterprise-grade blockchain APIs.

Endpoints are intended for development, testing, and education. Traffic is subject to fair-use limits so the community stays fast and available for everyone. If you need higher throughput, dedicated nodes, or contractual SLAs, Tatum’s paid plans add priority routing, monitoring, and support tailored to production teams.

Each chain page lists mainnet and testnet interfaces where available, plus links to documentation and official explorers so you can verify transactions and integrate quickly with wallets and libraries you already use.

We improve coverage over time as networks evolve. If you spot an outdated explorer link or a missing interface, contact us through the channels on our contact page.

Public gateways share capacity across many developers. That keeps the service free, but it also means bursts of traffic may be throttled to protect the rest of the community. For predictable latency, use retries with backoff, cache chain metadata locally, and avoid hammering the same method in tight loops when you can batch reads or use websockets where a chain supports them through Tatum’s broader product suite.

Educators and hackathon organizers often point students here because there is no onboarding friction: copy an HTTPS URL, paste it into a framework’s RPC field, and start sending calls. Teams evaluating multiple chains use FREERPC.com to compare developer experience before they standardize on one network for a pilot.

Free covers every interface this site lists, JSON-RPC, REST, WebSocket and gRPC alike, at a flat 5 requests per minute, with no API key, no signup form, and no credit card on file. What Tatum Premium adds is not a different set of interfaces but archive node access, batch RPC calls, debug and trace methods, priority support, and a far higher ceiling, as the FAQ on every chain page spells out. The free ceiling is deliberately tight: enough to build and debug an integration end to end, run a hackathon demo, or teach a class, but not enough to carry production traffic unnoticed.

Every chain page follows the same layout. The Gateway section lists each network the chain’s feed reports, together with its interface type, JSON-RPC, WebSocket, REST, or gRPC depending on what that chain speaks, and a copyable endpoint URL. Below it, the Methods section lists the methods that interface answers, taken from method lists captured from the endpoints themselves and shipped with the site rather than assumed from a spec, and explains whether the chain has a public test network, what it is called, and how it differs from mainnet, so a chain without one does not get a paragraph describing one anyway.

Each page also carries its own FAQ, answering the same practical questions for that chain: how to point a wallet or Web3 library at the endpoint, what happens past the free tier’s rate limit, how mainnet and testnet differ there, and where to look when a connection fails. Where an interface supports it, the Methods section adds a short profile too: what that interface is good at, where it falls short next to the others on offer, and the specific error codes you are most likely to hit calling it, with what to do about each one.

If a chain you need is not listed yet, or an endpoint you rely on starts erroring, timing out, or falling behind the tip of the chain, the contact page lists where to raise it. Name the specific method, the network, and an approximate timestamp in UTC when you do, because a report without them cannot be reproduced by anyone reading it.

The free tier is not a substitute for running your own node, and it is not sized for high-frequency trading, indexing a chain’s entire history, or any workload that treats 5 requests a minute as a soft limit to route around with multiple IPs.

For production workloads with higher limits and SLAs, see Tatum Premium.
