Use Chomp Shopper's public REST API to read your recipes, make shopping lists and send them to Instacart.

Getting started

Everything you need to start using the Chomp Shopper API

Base URL

https://chompshopper.com/api/v1

Authentication

All API requests require authentication using an API key. Include your key in theX-API-Key header:

  https://chompshopper.com/api/v1/me

Rate limiting

Free: 100 requests/hour
Premium: 1,000 requests/hour

Limits apply per API key.

Response format

All responses are returned in JSON format. Successful responses include the requested data, while errors include an error field.

// Success response

  ...
}

// Error response
