direct-access-py

A thin wrapper around Drillinginfo's Direct Access API. Handles authentication and token management, pagination and network-related error handling/retries.

This module is built and tested on Python 3.6 but should work on Python 2.7 and up.

Install

pip install directaccess

Usage

Direct Access Version 1 (deprecated)

Version 1 of the API has been deprecated and removed.

Direct Access Version 2

For version 2 of the API, create an instance of the DirectAccessV2 class, providing it your API key, client id and client secret. The returned access token will be available as an attribute on the instance (d2.access_token) and the Authorization header is set automatically

from directaccess import DirectAccessV2

d2 = DirectAccessV2(
    api_key='<your-api-key>',
    client_id='<your-client-id>',
    client_secret='<your-client-secret>',
)

Provide the query method the dataset and query params. All query parameters must match the valid parameters found in the Direct Access documentation and be passed as keyword arguments.

for row in d2.query('well-origins', county='REEVES', pagesize=10000):
    print(row)

Filter functions

Direct Access version 2 supports filter funtions. These can be passed as strings on the keyword arguments.

Some common filters are greater than (gt()), less than (lt()), null, not null (not(null)) and between (btw()).
See the Direct Access documentation for a list of all available filters.

# Get well records updated after 2018-08-01 and without deleted dates
for row in d2.query('well-origins', updateddate='gt(2018-08-01)', deleteddate='null'):
    print(row)

# Get permit records with approved dates between 2018-03-01 and 2018-06-01
for row in d2.query('permits', approveddate='btw(2018-03-01,2018-06-01)'):
    print(row) 

You can use the fields keyword to limit the returned fields in your request.

for row in d2.query('rigs', fields='DrillType,LeaseName,PermitDepth'):
    print(row)

Escaping

When making requests containing certain characters like commas, use a backslash to escape them.

# Escaping the comma before LLC
for row in d2.query('producing-entities', curropername='PERCUSSION PETROLEUM OPERATING\, LLC'):
    print(row)

Network request handling

This module exposes functionality in python-requests for modifying network requests handling, namely:

• retries and backoff
• network proxies
• ssl verification

Retries and backoff

Specify the number of retry attempts in retries and the backoff factor in backoff_factor. See the urllib3 Retry utility API for more info

from directaccess import DirectAccessV2

d2 = DirectAccessV2(
    api_key='<your-api-key>',
    client_id='<your-client-id>',
    client_secret='<your-client-secret>',
    retries=5,
    backoff_factor=1
)

You can specify a network proxy by passing a dictionary with the host and port of your proxy to proxies. See the proxies section of the python-requests documentation for more info.

from directaccess import DirectAccessV2

d2 = DirectAccessV2(
    api_key='<your-api-key>',
    client_id='<your-client-id>',
    client_secret='<your-client-secret>',
    proxies={'https': 'http://10.10.1.10:1080'}
)

Finally, if you're in an environment that provides its own SSL certificates that might not be in your trusted store, you can choose to ignore SSL verification altogether. This is typically not a good idea and you should seek to resolve certificate errors instead of ignore them.

from directaccess import DirectAccessV2

d2 = DirectAccessV2(
    api_key='<your-api-key>',
    client_id='<your-client-id>',
    client_secret='<your-client-secret>',
    verify=False
)
