-## 0x-contract-demo
-
-A demonstration of calling 0x smart contracts from Python.
-
-Read the [documentation](http://0x-contract-demo-py.s3-website-us-east-1.amazonaws.com/)
-
-## Contributing
-
-We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
-
-Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
-
-### Install Code and Dependencies
-
-Ensure that you have installed Python >=3.6 and Docker. Then:
-
-```bash
-pip install -e .[dev]
-```
-
-### Test
-
-Tests depend on a running ganache instance with the 0x contracts deployed in it. For convenience, a docker container is provided that has ganache-cli and a snapshot containing the necessary contracts. A shortcut is provided to run that docker container: `./setup.py ganache`. With that running, the tests can be run with `./setup.py test`.
-
-### Clean
-
-`./setup.py clean --all`
-
-### Lint
-
-`./setup.py lint`
-
-### Build Documentation
-
-`./setup.py build_sphinx`
-
-### More
-

-# 0x-sra-client
-
-A Python client for interacting with servers conforming to [the Standard Relayer API specification](https://github.com/0xProject/0x-monorepo/tree/development/packages/sra-spec).
-
-# Schemas
-
-The [JSON schemas](http://json-schema.org/) for the API payloads and responses can be found in [@0xproject/json-schemas](https://github.com/0xProject/0x-monorepo/tree/development/packages/json-schemas). Examples of each payload and response can be found in the 0x.js library's [test suite](https://github.com/0xProject/0x-monorepo/blob/development/packages/json-schemas/test/schema_test.ts#L1).
-
-```bash
-pip install 0x-json-schemas
-```
-
-You can easily validate your API's payloads and responses using the [0x-json-schemas](https://github.com/0xProject/0x.js/tree/development/python-packages/json_schemas) package:
-
-```python
-from zero_ex.json_schemas import assert_valid
-from zero_ex.order_utils import Order
-
-order: Order = {
-    'makerAddress': "0x0000000000000000000000000000000000000000",

-# Pagination
-
-Requests that return potentially large collections should respond to the **?page** and **?perPage** parameters. For example:
-
-```bash
-$ curl https://api.example-relayer.com/v2/asset_pairs?page=3&perPage=20
-```
-
-Page numbering should be 1-indexed, not 0-indexed. If a query provides an unreasonable (ie. too high) `perPage` value, the response can return a validation error as specified in the [errors section](#section/Errors). If the query specifies a `page` that does not exist (ie. there are not enough `records`), the response should just return an empty `records` array.
-
-All endpoints that are paginated should return a `total`, `page`, `perPage` and a `records` value in the top level of the collection. The value of `total` should be the total number of records for a given query, whereas `records` should be an array representing the response to the query for that page. `page` and `perPage`, are the same values that were specified in the request. See the note in [miscellaneous](#section/Misc.) about formatting `snake_case` vs. `lowerCamelCase`.
-
-These requests include the [`/v2/asset_pairs`](#operation/getAssetPairs), [`/v2/orders`](#operation/getOrders), [`/v2/fee_recipients`](#operation/getFeeRecipients) and [`/v2/orderbook`](#operation/getOrderbook) endpoints.
-
-# Network Id
-
-All requests should be able to specify a **?networkId** query param for all supported networks. For example:
-
-```bash
-$ curl https://api.example-relayer.com/v2/asset_pairs?networkId=1
-```
-
-If the query param is not provided, it should default to **1** (mainnet).
-
-Networks and their Ids:
-
-| Network Id | Network Name |
-| ---------- | ------------ |
-| 1          | Mainnet      |
-| 42         | Kovan        |
-| 3          | Ropsten      |
-| 4          | Rinkeby      |
-
-If a certain network is not supported, the response should **400** as specified in the [error response](#section/Errors) section. For example:
-
-```json
-{
-    \"code\": 100,
-    \"reason\": \"Validation failed\",
-    \"validationErrors\": [
-        {
-            \"field\": \"networkId\",
-            \"code\": 1006,
-            \"reason\": \"Network id 42 is not supported\"
-        }
-    ]
-}
-```
-
-# Link Header
-
-A [Link Header](https://tools.ietf.org/html/rfc5988) can be included in a response to provide clients with more context about paging
-For example:
-
-```bash
-Link: <https://api.example-relayer.com/v2/asset_pairs?page=3&perPage=20>; rel=\"next\",
-<https://api.github.com/user/repos?page=10&perPage=20>; rel=\"last\"
-```
-
-This `Link` response header contains one or more Hypermedia link relations.
-
-The possible `rel` values are:
-
-| Name  | Description                                                   |
-| ----- | ------------------------------------------------------------- |
-| next  | The link relation for the immediate next page of results.     |
-| last  | The link relation for the last page of results.               |
-| first | The link relation for the first page of results.              |
-| prev  | The link relation for the immediate previous page of results. |
-
-# Rate Limits
-
-Rate limit guidance for clients can be optionally returned in the response headers:
-
-| Header Name           | Description                                                                  |
-| --------------------- | ---------------------------------------------------------------------------- |
-| X-RateLimit-Limit     | The maximum number of requests you're permitted to make per hour.            |
-| X-RateLimit-Remaining | The number of requests remaining in the current rate limit window.           |
-| X-RateLimit-Reset     | The time at which the current rate limit window resets in UTC epoch seconds. |
-
-For example:
-
-```bash
-$ curl -i https://api.example-relayer.com/v2/asset_pairs
-HTTP/1.1 200 OK
-Date: Mon, 20 Oct 2017 12:30:06 GMT
-Status: 200 OK
-X-RateLimit-Limit: 60
-X-RateLimit-Remaining: 56
-X-RateLimit-Reset: 1372700873
-```
-
-When a rate limit is exceeded, a status of **429 Too Many Requests** should be returned.
-
-# Errors
-
-Unless the spec defines otherwise, errors to bad requests should respond with HTTP 4xx or status codes.
-
-## Common error codes
-
-| Code | Reason                                  |
-| ---- | --------------------------------------- |
-| 400  | Bad Request – Invalid request format    |
-| 404  | Not found                               |
-| 429  | Too many requests - Rate limit exceeded |
-| 500  | Internal Server Error                   |
-| 501  | Not Implemented                         |
-
-## Error reporting format
-
-For all **400** responses, see the [error response schema](https://github.com/0xProject/0x-monorepo/blob/development/packages/json-schemas/schemas/relayer_api_error_response_schema.ts#L1).
-
-```json
-{
-    \"code\": 101,
-    \"reason\": \"Validation failed\",
-    \"validationErrors\": [
-        {
-            \"field\": \"maker\",
-            \"code\": 1002,
-            \"reason\": \"Invalid address\"
-        }
-    ]
-}
-```
-
-General error codes:
-
-```bash
-100 - Validation Failed
-101 - Malformed JSON
-102 - Order submission disabled
-103 - Throttled
-```
-
-Validation error codes:
-

-
-# Asset Data Encoding
-
-As we now support multiple [token transfer proxies](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#assetproxy), the identifier of which proxy to use for the token transfer must be encoded, along with the token information. Each proxy in 0x v2 has a unique identifier. If you're using 0x.js there will be helper methods for this [encoding](https://0xproject.com/docs/0x.js#zeroEx-encodeERC20AssetData) and [decoding](https://0xproject.com/docs/0x.js#zeroEx-decodeAssetProxyId).
-
-The identifier for the Proxy uses a similar scheme to [ABI function selectors](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI#function-selector).
-
-```js
-// ERC20 Proxy ID  0xf47261b0
-bytes4(keccak256('ERC20Token(address)'));
-// ERC721 Proxy ID 0x02571792
-bytes4(keccak256('ERC721Token(address,uint256)'));
-```
-
-Asset data is encoded using [ABI encoding](https://solidity.readthedocs.io/en/develop/abi-spec.html).
-
-For example, encoding the ERC20 token contract (address: 0x1dc4c1cefef38a777b15aa20260a54e584b16c48) using the ERC20 Transfer Proxy (id: 0xf47261b0) would be:
-
-```bash
-0xf47261b00000000000000000000000001dc4c1cefef38a777b15aa20260a54e584b16c48
-```
-
-Encoding the ERC721 token contract (address: `0x371b13d97f4bf77d724e78c16b7dc74099f40e84`), token id (id: `99`, which hex encoded is `0x63`) and the ERC721 Transfer Proxy (id: 0x02571792) would be:
-
-```bash
-0x02571792000000000000000000000000371b13d97f4bf77d724e78c16b7dc74099f40e840000000000000000000000000000000000000000000000000000000000000063
-```
-
-For more information see [the Asset Proxy](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#erc20proxy) section of the v2 spec and the [Ethereum ABI Spec](https://solidity.readthedocs.io/en/develop/abi-spec.html).
-
-# Meta Data in Order Responses
-
-In v2 of the standard relayer API we added the `metaData` field. It is meant to provide a standard place for relayers to put optional, custom or non-standard fields that may of interest to the consumer of the API.
-
-A good example of such a field is `remainingTakerAssetAmount`, which is a convenience field that communicates how much of a 0x order is potentially left to be filled. Unlike the other fields in a 0x order, it is not guaranteed to be correct as it is derived from whatever mechanism the implementer (ie. the relayer) is using. While convenient for prototyping and low stakes situations, we recommend validating the value of the field by checking the state of the blockchain yourself, such as by using [Order Watcher](https://0xproject.com/wiki#0x-OrderWatcher).
-
-# Misc.
-
--   All requests and responses should be of **application/json** content type
--   All token amounts are sent in amounts of the smallest level of precision (base units). (e.g if a token has 18 decimal places, selling 1 token would show up as selling `'1000000000000000000'` units by this API).
--   All addresses are sent as lower-case (non-checksummed) Ethereum addresses with the `0x` prefix.
--   All parameters are to be written in `lowerCamelCase`.

-# **get_order_config**
-
-> RelayerApiOrderConfigResponseSchema get_order_config(network_id=network_id, relayer_api_order_config_payload_schema=relayer_api_order_config_payload_schema)
-
-Relayers have full discretion over the orders that they are willing to host on their orderbooks (e.g what fees they charge, etc...). In order for traders to discover their requirements programmatically, they can send an incomplete order to this endpoint and receive the missing fields, specifc to that order. This gives relayers a large amount of flexibility to tailor fees to unique traders, trading pairs and volume amounts. Submit a partial order and receive information required to complete the order: `senderAddress`, `feeRecipientAddress`, `makerFee`, `takerFee`.

-# **get_orderbook**
-
-> RelayerApiOrderbookResponseSchema get_orderbook(base_asset_data, quote_asset_data, network_id=network_id, page=page, per_page=per_page)
-
-Retrieves the orderbook for a given asset pair. This endpoint should be [paginated](#section/Pagination). Bids will be sorted in descending order by price, and asks will be sorted in ascending order by price. Within the price sorted orders, the orders are further sorted by _taker fee price_ which is defined as the **takerFee** divided by **takerTokenAmount**. After _taker fee price_, orders are to be sorted by expiration in ascending order. The way pagination works for this endpoint is that the **page** and **perPage** query params apply to both `bids` and `asks` collections, and if `page` \* `perPage` > `total` for a certain collection, the `records` for that collection should just be empty.

-
-Retrieves a list of orders given query parameters. This endpoint should be [paginated](#section/Pagination). For querying an entire orderbook snapshot, the [orderbook endpoint](#operation/getOrderbook) is recommended. If both makerAssetData and takerAssetData are specified, returned orders will be sorted by price determined by (takerTokenAmount/makerTokenAmount) in ascending order. By default, orders returned by this endpoint are unsorted.
