Don't have a key yet? Visit your [account settings](https://mijn.prospectpro.nl/accounts) and grab your API key from the \"Script & API\" section. Don't have an account yet? [Sign up](https://mijn.prospectpro.nl/register) to start your free trial.\n\n## Pagination\n\n---\n\nPagination is only available for the **/prospects** endpoint.\n\n| **Param** | **Description** |\n| --- | --- |\n| limit | Number of results per page. |\n| page | Number of the page you want to retrieve. |\n| start | Alternative to page. Number of the first result you want to retrieve. |\n\n## Rate Limits\n\n---\n\nProspectPro is designed to handle heavy API usage (fair use). If you ensure you don't make >1 request per endpoint per second (per account), you'll never hit a limit. But if you temporarily need a burst, our servers usually don't mind.","schema":"https://schema.getpostman.com/json/collection/v2.0.0/collection.json","isPublicCollection":false,"owner":"37888696","team":6409852,"collectionId":"d446dda4-1d72-4da9-9bb2-c4d60d99317a","publishedId":"2sAXjF8uWR","public":true,"publicUrl":"https://docs.prospectpro.nl","privateUrl":"https://go.postman.co/documentation/37888696-d446dda4-1d72-4da9-9bb2-c4d60d99317a","customColor":{"top-bar":"FFFFFF","right-sidebar":"0d1b2a","highlight":"0075f2"},"documentationLayout":"classic-double-column","customisation":{"metaTags":[{"name":"description","value":"Leverage the ProspectPro API to continuously feed new prospects into your sales and marketing tools.
