# Build with AI

> Wire BlockDB into AI coding tools — a Cursor rule and a Claude skill, tuned to our API and free datasets, that query on-chain data in natural language.

BlockDB is built to be called by machines. The schema is stable, every endpoint is `POST` + JSON, and responses carry lineage. These pages give you drop-in artifacts so your AI tools can query our API and datasets without you writing glue code.

<CardGroup cols={2}>
  <Card title="Cursor" icon="laptop-code" href="/build-with-ai/cursor">
    A ready-to-paste rule that teaches Cursor to call the API correctly.
  </Card>

  <Card title="Claude Skill" icon="sparkles" href="/build-with-ai/claude-skills">
    A SKILL.md that turns Claude into a BlockDB query agent.

## Start here

Every artifact below builds on the same instruction set. If you're wiring up something custom, point your model at [LLM onboarding](/api-reference/overview/llm-onboarding) — it covers auth, pagination, limits, and the rules that keep generated requests valid.

<Note>
  All paths need an API key (`Authorization: Bearer <API_KEY>`). Create one at [dashboard.blockdb.io](https://dashboard.blockdb.io). Free [historical datasets](/free-datasets/home) need no key at all.
