Setup

ℹ️ The library currently only supports personal use, where the client id and credentials are from the same account. Support for multi-account mode is planned.

Config file location

• Linux/Unix: $HOME/.config/prosper-api/config.toml
• Windows: %HOMEDIR%%HOMEPATH\AppData\Local\prosper-api\prosper-api\config.toml
• MacOs: $HOME/Library/Application Support/prosper-api/config.toml

Default

Create a config file with the following contents:

[credentials]
client-id = "0123456789abcdef0123456789abcdef"
client-secret = "fedcba9876543210fedcba9876543210"
username = "PROBABLY_YOUR_EMAIL_ADDRESS"
password = "AWESOME_PASSWORD"

More secure

ℹ️ You must have installed keyring or used the '[secure]' mode when installing the library.

Remove the client-secret and password portions of the config:

[credentials]
client-id = "0123456789abcdef0123456789abcdef"
username = "PROBABLY_YOUR_EMAIL_ADDRESS"

Run the following to store your credentials securely in your OS credentials storage, e.g. Keychain for MacOS, etc. For each command, you will be prompted to enter the corresponding secret. For 'CLIENT_ID', enter the client secret. For 'USERNAME' enter the corresponding password.

keyring set prosper-api {CLIENT_ID}
keyring set prosper-api {USERNAME}

See a sample bot for concrete usage.

offset = 0
while True:
    result: SearchListingsResponse = client.search_listings(SearchListingsRequest(invested=False, biddable=True, limit=PAGE_SIZE, offset=offset))
    listings += result.result
