--- title: "Agent Skills" url: "https://docs.unified.to/skills" description: "Agent Skills for AI coding agents: ready-to-use SKILL.md packages that teach agents how to build against the Unified.to APIs for payments, e-commerce, ATS, accounting, assessments, and RAG." --- # Agent Skills **Agent Skills** are self-contained instruction packages that teach AI coding agents — like Claude Code, Cursor, and others — how to build against a specific Unified.to API for a common use case. Each skill maps one of our top [How-To guides](/guides) to a ready-to-use `SKILL.md` file containing the endpoints, authentication, pagination, SDK usage, and sync patterns an agent needs to ship the integration. ## How to use a skill Point your AI coding agent at the skill's `SKILL.md` file, or add it to your project: * **Claude Code / Cursor:** drop the `SKILL.md` into your project (e.g. `.claude/skills//SKILL.md`) so the agent can load it on demand. * **Any agent:** fetch the raw file at its URL and paste it, or reference it, as context before you start building. ### Build a payments / fintech app Payment Accept payments, manage subscriptions, and reconcile payouts and refunds across Stripe, GoCardless, and other providers with the Unified Payment API.

Set these up once: 1. Grab your **Workspace ID** and **API key** from [Settings → API Keys](https://app.unified.to/settings/api). 2. Activate the relevant integration in the [Sandbox environment](/concepts/sandbox) to develop against mocked data. 3. Add the [embedded Authorization component](/concepts/embedded-components) so your end-users can connect their accounts and you receive a **connection ID**. 4. Use webhooks to [keep data in sync](/reference/webhooks) instead of polling.
