TMG price API

TMG is a token on Signum cryptocurrency. Price is based on TMG liquidity pool at deleterium.info.

Setup

Install and configure Apache.
Install and configure PHP.
Install and configure MariaDB.
Create new database.
Create new table with the command:

CREATE TABLE tmg_prices (
  epoch INT(11) NOT NULL,
  price DECIMAL(18,8) NOT NULL,
  blockheight INT(11) NOT NULL,
  volume DECIMAL(18,8) NOT NULL,
  PRIMARY KEY (epoch)
);

Create a file named .config.php with your own configuration. Use the .config.php.template for convenience.
Run manually the .update.php. First time it takes a while to get all values. Best way if you have a signum localhost, but remember database trim must be disabled (it is enabled by default).
Add a cron job to run every 5 minutes to update the database, running the .update.php file. This will keep track of new records.
Inspect regularly the update.log file checking for errors.
