Perplexity

Script NationBuilder updates

Claude Code executes `create_new_signup` within your CI/CD pipelines or shell scripts. It handles the data payload, ensuring your signup flow stays consistent. It checks connection health first with `get_api_status`. This prevents broken builds by verifying the API is ready before it attempts to write new records.

Automate donation processing

Pipe the output of your payment processor directly into `record_donation`. Claude Code manages the authentication headers and confirms the transaction record. This is ideal for cron jobs that need to sync external transactions. It turns your terminal into a command center for your campaign finances.

List nation assets

Query `list_nation_sites` or `list_custom_people_lists` to pull inventory into your terminal. You can pipe this output to other CLI utilities for analysis. It allows for rapid iteration on your data. You don't need a browser to see which lists or sites are active in your account.
