 ## Features
 The following features set this repository apart from rest.bitcoin.com:
 
-- Address balance and UTXO queries use the [Blockbook](https://github.com/trezor/blockbook)
-indexer instead of Insight.
 - Fine grain access is controlled with a JWT token using
-[this back end auth server](https://github.com/Permissionless-Software-Foundation/jwt-bch-api) and [this front end](https://github.com/Permissionless-Software-Foundation/jwt-bch-frontend).
-- Default rate limits are set to 3 RPM for anonymous connections, 10 RPM for [free accounts](https://fullstack.cash/pricing), up to 100 RPM if a full-access JWT token is used.
+[this back end auth server](https://github.com/Permissionless-Software-Foundation/jwt-bch-api) and [this front end](https://github.com/Permissionless-Software-Foundation/jwt-bch-frontend). Can be used to monetize access to the REST API.
 - Typescript removed and ES8 JavaScript used instead.
-- npm audit run on all dependencies.
-- [Greenkeeper](https://greenkeeper.io/) implemented for automatic dependency management
-and security updates.
+- `npm audit fix` frequently run to fix dependencies.
 
 ## Live Demo
 You can test a live demo of the REST API by running the
 [bch-js examples](https://github.com/Permissionless-Software-Foundation/bch-js-examples).
-Rate limits are 3 requests per minute, but you can increase them to 10 with a [free account](https://fullstack.cash/pricing).
-This is fast enough to try out the examples
-but these servers are not intended as a freemium service. You can run your own
-REST server by purchasing the hard drive at [bchjs.cash](https://bchjs.cash).
+Rate limits are 20 requests per minute, but you can increase them to 100 with a [paid account](https://fullstack.cash/pricing).
+You can bootstrap your own REST API server by downloading and installing the infrastructure listed on the [CashStrap](https://fullstack.cash/cashstrap) page.
 
-- Mainnet REST API server: https://api.fullstack.cash/v3/
-- Testnet REST API server: https://tapi.fullstack.cash/v3/
+### Configure bch-js
+The live servers can be used by [bch-js](https://github.com/Permissionless-Software-Foundation/bch-js) by settings the `restURL` config property to one of these servers:
+
+- BCHN Mainnet REST API server: https://bchn.fullstack.cash/v4/
+- ABC Mainnet REST API server: https://abc.fullstack.cash/v4/
+- Testnet3 REST API server: https://testnet3.fullstack.cash/v4/
 - Check server status: https://metrics.fullstack.cash
 
 ## Installation
 There are two installation paths, depending if you want a *development* or
 *production* environment. You'll also need to set up the underlying infrastructure

+## Rate Limits
+The rate limits for [api.fullstack.cash](https://api.fullstack.cash) are controlled by a JWT token. You can increase your rate limits by [purchasing a JWT token](https://https://fullstack.cash). If you're using bch-js, [check the readme for instructions on increasing rate limits](https://github.com/Permissionless-Software-Foundation/bch-js#api-key). For interacting with bch-api directly, you can then include the JWT token in the HTTP header like this:
+
+- `Authorization: Token <JWT token>`
+
+### cURL example
+Here is an example using curl for using the JWT token when making a call to the REST API:
+
+```
+export BCHJSTOKEN=eyJhbGciOiJ....
+
+curl "https://bchn.fullstack.cash/v4/electrumx/balance/bitcoincash:qr69kyzha07dcecrsvjwsj4s6slnlq4r8c30lxnur3" -X GET -H "Content-Type: application/json" -H "Authorization: Token ${BCHJSTOKEN}"

+- 100 points per call for tier 40 (100 RPM)
+- 40 points per call for tier 50 (250 RPM)
+- 16 points per call for tier 60 (625 RPM)

+The rate limit handling is designed for these four use cases:
+- Users who want to buy a JWT token for 24 hour access.
+- Users who want to buy different RPM tiers: 100, 250, 600
+- Basic Authentication which should not have any rate limits applied.
+- Local installations that do not want any authentication or rate limits at all.
+
+The Basic Auth use cases is considered when determining internal rate limits.
+The internal rate limits should not be applied to calls from those users.
+
+A lot of attention has been paid to passing rate-limit information for the user
+when they trigger an endpoint that makes a lot of internal API calls. Examples
+are hydrateUtxos() and getPublicKey(). These keeps things fair by charging the
