## What it does

The skill teaches the agent to call paid APIs through `npx agentcash@latest`. It ships a table of services: `stableenrich.dev` for people and company search, web search and scraping, `stablesocial.dev` for social media data, `stablestudio.dev` for image and video generation, `stableemail.dev` for email, `stablephone.dev` for calls, `stabletravel.dev` for flights, `stablebrowser.dev` for browser automation. When a task matches one of these origins, the agent skips search and goes straight to `discover`.

The flow is short. `discover <origin>` lists endpoints and prices, `check <endpoint-url>` returns the request schema, then `fetch` makes the call. Payment settles from a USDC wallet on Base or Solana. Failed requests (non-2xx) cost nothing. Before expensive operations the skill advises checking the balance with `npx agentcash@latest balance` — video generation can run $1-3 per call.

A zero balance is the usual blocker. The agent will point you to `npx agentcash@latest fund`, `accounts` for deposit links, or `redeem <code>` for an invite code. For services outside the list there is `npx agentcash@latest add <origin>`, which persists a lightweight skill. `fetch-auth` still works but is a deprecated alias for `fetch`; new workflows should use `fetch`.
