Installation

1. Install cardano-node and Ogmios server as described here. (Docker installation is recommended.)
2. Install ogmios-python from PyPI using pip:

pip install ogmios

Quickstart

To see how easy it is to build on Cardano with ogmios-python, let's use the library to view new blocks as they are added to the blockchain:

import time
import ogmios

with ogmios.Client() as client:
    # Set chain pointer to origin
    _, tip, _ = client.find_intersection.execute([ogmios.Origin()])

    # Now set chain pointer to tip
    _, _, _ = client.find_intersection.execute([tip.to_point()])

    # Tail blockchain as new blocks come in beyond the current tip
    while True:
        client.next_block.execute()
        time.sleep(1)

For more examples, see the documentation and example scripts in the repo.
