About IndiePitcher
IndiePitcher provides a REST API for sending transactional emails, managing contacts, and handling mailing lists. It supports sending emails to individual addresses, to registered contacts, or to contacts subscribed to a specific mailing list, with email bodies accepted in markdown or plain HTML. Contact management endpoints cover retrieving, finding, adding (single or bulk), and updating contacts, as well as generating portal session URLs that let contacts manage their own mailing list subscriptions.
Authentication uses a bearer API key tied to a project, and the API enforces a rate limit of 10 requests per second per project. Destructive operations are largely restricted to the IndiePitcher dashboard rather than exposed through the API, for security reasons. SDKs are provided for Node.js, Swift, and Python, and an OpenAPI spec is published for the API.
The product is aimed at developers integrating transactional and list-based email sending, along with contact and subscription management, into their own applications.

Frequently asked questions
What languages have official SDKs?
IndiePitcher provides SDKs for Node.js, Swift (server-side usage only), and Python (sync and async).
What are the API rate limits?
Requests are limited to 10 per second across API keys tied to a project, with a 429 response returned after the limit is reached and reset after 1 second.
How do I authenticate API requests?
You create a free account to get an API key, then include it as a Bearer token in the Authorization header of requests to https://api.indiepitcher.com/v1.
Can I call the API directly from frontend code?
No, IndiePitcher advises against exposing the API key in frontend code due to exploitation risk, and CORS security rules block such requests.
Can I delete contacts or perform destructive operations via the API?
Most destructive operations are not supported through the REST API for security reasons; the IndiePitcher dashboard should be used instead, though contact deletion is available via the API.
