Cardano Token Registry API

A simple API for the Cardano Token Registry

Components

This project has 2 components:

1. A script that will populate and update a small Sqlite3 database with the information from the Cardano Token Registry. The Cardano Token Registry repository was added as a git submodule in the "files" folder (configurable in config.py). Then the update.py script must be executed, to populate the database. The repository must be updated from time to time and the update.py script should be run if there are changes to the repository files. This script can be run with the command: python3 update.py.
2. The API script, main.py, which starts a daemon running on a configurable port (8050 is the default port, it can be configured in config.py). This script can be run with the command: python3 main.py.

In order to also update the Cardano Token Registry submodule, the repository should be initially cloned with the command: git clone --recurse-submodules When updating it, the update should be done with the following command: git pull --recurse-submodules

Endpoints

There are 3 API endpoints:

1. /api/v0/ticker/{ticker} The ticker is case-sensitive. A GET request to: /api/v0/cNETA will return the following result:

[
  {
    "policy_id": "b34b3ea80060ace9427bda98690a73d33840e27aaa8d6edb7f0c757a",
    "name_hex": "634e455441",
    "name": "anetaBTC",
    "ticker": "cNETA",
    "description": "AnetaBTC is a fully on-chain, decentralized protocol that allows Bitcoin to be directly wrapped on the Ergo and Cardano blockchains. This token serves as a Cardano governance token for anetaBTC.",
    "decimals": 0
  }
]

If the ticker is not found, the result will be (code 406):

[
  {
    "error": "Ticker <ticker> not found"
  }
]

2. /api/v0/token/token_policy/token_name A GET request to /api/v0/token/b34b3ea80060ace9427bda98690a73d33840e27aaa8d6edb7f0c757a/634e455441 will return the following result:

[
  {
    "name": "anetaBTC",
    "ticker": "cNETA",
    "description": "AnetaBTC is a fully on-chain, decentralized protocol that allows Bitcoin to be directly wrapped on the Ergo and Cardano blockchains. This token serves as a Cardano governance token for anetaBTC.",
    "decimals": 0
  }
]

3. /api/v0/tokens A POST request to /api/v0/tokens with the parameter [{"policy_id": "b34b3ea80060ace9427bda98690a73d33840e27aaa8d6edb7f0c757a", "token_name": "634e455441"}, {"policy_id": "6ac8ef33b510ec004fe11585f7c5a9f0c07f0c23428ab4f29c1d7d10", "token_name": "4d454c44"}] will return the following result:

[
  {
    "policy_id": "6ac8ef33b510ec004fe11585f7c5a9f0c07f0c23428ab4f29c1d7d10",
    "name_hex": "4d454c44",
    "name": "MELD",
    "ticker": "MELD",
    "description": "The governance token of the MELD protocol.",
    "decimals": 6
  },
  {
    "policy_id": "b34b3ea80060ace9427bda98690a73d33840e27aaa8d6edb7f0c757a",
    "name_hex": "634e455441",
    "name": "anetaBTC",
    "ticker": "cNETA",
    "description": "AnetaBTC is a fully on-chain, decentralized protocol that allows Bitcoin to be directly wrapped on the Ergo and Cardano blockchains. This token serves as a Cardano governance token for anetaBTC.",
    "decimals": 0
  }
]

Support or donations

I created this script and made it open source because I thought it might be useful for some people. I do not expect any compensation for it. But in case someone finds it very useful and wants to support me, the best way to do it is to delegate a Cardano wallet to APEX Stake pool (ticker: APEX, pool ID: 538299a358e79a289c8de779f8cd09dd6a6bb286de717d1f744bb357). And in case someone really wants to make a donation in ADA or other Cardano native tokens, this is the address that can be used: addr1vy923jc5f2gck5eqzwyl8nkn4a8rc6s6w2td83egm4malns79qumx. Thank you!
