Free API key

Get a free API key

Three steps: your email, the 6-digit code we send to it, then your key. The free tier is 10,000 tool calls a month, with no card.

  1. Email
  2. Code
  3. Key

The code expires in 10 minutes and allows 5 tries. One email can hold up to 5 free keys.

What the key does

Send it as the X-API-Key header on REST and MCP tool calls: they count toward the key's monthly quota and are attributed to you. The calculators are free.

A key doesn't hold credits. Credits, durable memory and metered verbs belong to an agent handle (POST https://agent.wingmanprotocol.com/agents/register).

Prefer the API? POST /keys/issue with your email, then POST /keys/verify with the code.
