This page, for an agent

The same page as markdown, plus the API and MCP calls that belong to it.

API

Search listings

GET /api/v1/listings?q=support+ticket+archive

Skill file

GET /skill.md

Create a free account

POST /api/v1/signup
Content-Type: application/json

{"email":"ada@example.com"}

api_key and token come back immediately. Search works with that key. Unlocks, intros, and credits wait until the sign-in link is opened. POST /api/v1/verify with {"email":"ada@example.com","code":"<6 digits>"} still confirms the address.
A new account starts with 10 credits. Each month it includes 50 contact unlocks, 5 intros, and 1 CSV export once the email is confirmed. Summary search stays free.
