Free Node RPC and Indexer RPC for CKB Developers

zhixian · September 9, 2020, 12:29am

Hey devs, we have deployed a pair of full-nodes as well as indexers for everyone to use, for free! here are the URLs:

Mainnet - Node RPC
https://mainnet.ckb.dev/
https://mainnet.ckb.dev/rpc
Mainnet - Indexer RPC
https://mainnet.ckb.dev/indexer

Testnet - Node RPC
https://testnet.ckb.dev/
https://testnet.ckb.dev/rpc
Testnet - Indexer RPC
https://testnet.ckb.dev/indexer

There are limit for frequency:
rate: 20 req / s
burst: 20 req / s
You will receive 500 Error if the limit is exceeded. If you have further requests, please let me know

Indexer RPC is using ckb-indexer，GitHub address https://github.com/nervosnetwork/ckb-indexer

Hey @zhixian , thanks for hosting these nodes and keeping them available for the community. Is there any documentation on the available endpoints, perhaps something like Swagger?

Thanks.

# CKB JSON-RPC Protocols

<!--**NOTE:** This file is auto-generated from code comments.-->

The RPC interface shares the version of the node version, which is returned in `local_node_info`. The interface is fully compatible between patch versions, for example, a client for 0.25.0 should work with 0.25.x for any x.

Allowing arbitrary machines to access the JSON-RPC port (using the `rpc.listen_address` configuration option) is **dangerous and strongly discouraged**. Please strictly limit the access to only trusted machines.

CKB JSON-RPC only supports HTTP now. If you need SSL, please set up a proxy via Nginx or other HTTP servers.

Subscriptions require a full duplex connection. CKB offers such connections in the form of TCP (enable with `rpc.tcp_listen_address` configuration option) and WebSockets (enable with `rpc.ws_listen_address`).

## JSONRPC Deprecation Process

A CKB RPC method is deprecated in three steps.

First, the method is marked as deprecated in the CKB release notes and RPC document. However, the RPC method is still available. The RPC document will have the suggestion of alternative solutions.

The CKB dev team will disable any deprecated RPC methods starting from the next minor version release. Users can enable the deprecated methods via the config file option rpc.enable_deprecated_rpc.

## Introduce

All the [indexing](https://github.com/nervosnetwork/ckb/tree/develop/rpc#indexer) RPCs built in the CKB has been deprecated since v0.36.0 and removed in v0.40.0. This is a standalone service for creating cell and transaction indexes as an alternate solution.

## Usage

Build binary from source

```bash
cargo build --release
```

Connect to default ckb rpc service at `http://127.0.0.1:8114` and stores the indexer data at `/tmp/ckb-indexer-test` folder
```bash
RUST_LOG=info ./target/release/ckb-indexer -s /tmp/ckb-indexer-test
```

Or connect to ckb rpc service at `tcp://127.0.0.1:18114`
```bash
RUST_LOG=info ./target/release/ckb-indexer -s /tmp/ckb-indexer-test -c tcp://127.0.0.1:18114
