When an agent uses get_credits

Call get_credits before a credit-spending operation so an agent can decide whether it has enough balance to run a batch or bulk job, and whether it needs to top up first. It returns the remaining balance plus usage today and this month. It is the natural pre-flight check ahead of buy_credits.

REST endpoint

Input schema

This tool takes no arguments — call it with an empty arguments object.

Call it over MCP

An MCP client invokes the tool with a tools/call request. Hosted clients send this to https://verifly.email/mcp with your Authorization: Bearer vf_… header; the verifly-mcp-server package does the same with VERIFLY_API_KEY set.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_credits",
    "arguments": {}
  }
}

Posting that same call straight to the hosted endpoint:

curl -s -X POST "https://verifly.email/mcp" \
  -H "Authorization: Bearer vf_your_api_key" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_credits","arguments":{}}}'

Equivalent raw REST call

Under the hood this tool calls GET /api/v1/credits. If you are not using MCP, hit the REST API directly:

curl -s "https://verifly.email/api/v1/credits" \
  -H "Authorization: Bearer vf_your_api_key"

What you get back

A JSON object with credits (remaining), used_today, used_this_month, and plan.
