Skip to main content
MoltSets is an identity resolution API. You give it a piece of data — an email address, LinkedIn URL, IP address, or hashed email — and it returns enriched contact and company information. Every tool follows the same request and response structure, so once you’ve made one call, you know how to make all of them.

​
Base URL

All API requests go to: 
https://api.moltsets.com/api/v1/tools/
Each tool has its own endpoint path. For example: 
POST https://api.moltsets.com/api/v1/tools/enrich_email
POST https://api.moltsets.com/api/v1/tools/ip_to_company
POST https://api.moltsets.com/api/v1/tools/get_account

​
How a request works

Every request is a POST with a JSON body, an Authorization header, and a Content-Type header: 
curl -X POST https://api.moltsets.com/api/v1/tools/enrich_email \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"linkedin_url": "https://linkedin.com/in/retentionadam"}'

​
How a response works

All responses return HTTP 200 with a consistent envelope: 
{
  "results": { ... },
  "status": "ok",
  "metadata": {
    "tokens_charged": 1,
    "tokens_remaining": 206
  }
}
  • results — the data returned by the tool. Empty object {} or empty array [] when no data is found.
  • status — always "ok" on a successful request, even when no data is found.
  • metadata.tokens_charged — credits consumed. Always 0 when no data is returned.
  • metadata.tokens_remaining — your remaining credit balance after this request.

Choosing a plan

The right plan depends on how fast you need results. Higher rate limits mean faster processing — the difference between waiting an hour and wrapping up in minutes.
