Step 01
The two keys
ColdIQ first: sign up, copy the key from the marketplace, then add it to Claude Code and restart. It can now call every provider directly.

Send a client their finished website before they ask
One list of 200 companies in. Two hundred finished sites out, each with the founder's verified email attached. Two API keys hold the whole thing up.

What you will build
An agent that takes a list of companies and returns, for each one, a finished page and the email of the person who decides. Not a template with their logo dropped in. A page built for them, with images made for them, live at a URL, before the first call.
The whole thing rests on two keys. ColdIQ covers finding who needs a site — 51 data providers and 821 endpoints behind one key. Higgsfield AI covers everything visual that goes on it, images and video, from one key.
The economics are the point. The hundredth site costs what the first one cost, because nothing in the loop is a person.
Prerequisites
What you need before you start
01 · Claude Code
The agent runs here. npm i -g @anthropic-ai/claude-code
02 · A ColdIQ key
One key for 51 providers and 821 endpoints. Billed only on the calls that find something.
03 · A Higgsfield AI key pair
A key ID and a key secret, sent together on every call. The API is asynchronous — build for polling from the start.

Copy-paste code. Any email works. Unlocks in your browser, so you only do this once.
Step 02
Find who needs one
Four calls, in this order, each one narrowing the list so the expensive steps run on fewer rows. Search companies that match the shape you sell to. Filter on a signal — hiring, funding, a new tool in the stack. Pull the decision maker. Verify the email.
