# Install on Claude Code

> Get the Arrays Skills running inside Claude Code in under a minute.

## Prerequisites

* [Claude Code](https://claude.com/claude-code) installed
* An Arrays API key from [arrays.org](https://arrays.org)

## 1. Clone the Skills repo

```bash theme={null}
git clone https://github.com/ArraysData/arrays-skills.git
```

## 2. Point Claude Code at the Skills

In your project, create or edit `.claude/CLAUDE.md` and reference the Skills directory:

```markdown theme={null}
# Project context

Use these Arrays Skills when answering financial-data questions:

@/absolute/path/to/arrays-skills/skills/
```

<Tip>
  Or symlink the `skills/` folder into your project root so the path is relative and portable across machines.
</Tip>

## 3. Set your API key

Add to your shell config (`~/.zshrc` or `~/.bashrc`):

```bash theme={null}
export ARRAYS_API_KEY="your_key_here"
export ARRAYS_API_BASE_URL="https://data-tools.prd.arrays.org/api"
```

Reload: `source ~/.zshrc`

## 4. Try it

In Claude Code, ask:

```
What was AAPL's revenue and net income last quarter?
```

Claude should automatically pick the `arrays-data-api-equity-fundamentals` Skill, call the `company/income-statements` endpoint, and return real numbers.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Claude doesn't seem to use the Skills">
    Verify `CLAUDE.md` is in the project root or `.claude/` folder, and that the path inside it is absolute or correctly resolved. Try running `claude --debug` to see which context files are loaded.
  </Accordion>

  <Accordion title="'Unauthorized' or 401 error">
    Check `echo $ARRAYS_API_KEY` is set in the same shell session where Claude Code runs. If you opened Claude Code from a GUI, export the var system-wide or use a `.env` file at the project root.
  </Accordion>

  <Accordion title="'Rate limit exceeded'">
    Free tier is capped at 100 req/day. See [Pricing](/pricing) for Pro and Enterprise quotas, or use [Nanopayment](/nanopayment/overview) for crypto endpoints with no quota.
