# GET /repo/tree: $0.002 per call

Every file in a public GitHub repository at a branch or tag, with sizes: the map an agent needs before reading code. Pass ?owner=honojs&repo=hono&ref=main (ref defaults to main, then master). Filter with path=src/ to one folder. Then read files with /repo/file.

- **Price:** $0.002 in USDC, the same on Base, Solana, Polygon, Arbitrum. Failed calls are never charged.
- **Free trial:** yes, 20 free calls a day from Claude, Cursor or any MCP client ([set-up](/mcp/setup)).
- **Answers cached for:** 30 min
- **Data sources:** jsDelivr data API (free)
- **Lane:** AI coding agents ([OpenAPI](/openapi/coding.json))
- **Live health:** [status page](/status)

## Free sample

See an answer for the demo input first, free (no payment, 10 a minute): [https://aayatai.com/sample/repo-tree](/sample/repo-tree). It is a stored real answer when we have one, otherwise an example marked `"kind": "illustrative"`.

```bash
curl "https://aayatai.com/sample/repo-tree"
```

## 1. See the price (free)

Call it without paying: you get `402 Payment Required` and a `PAYMENT-REQUIRED` header with the exact price and where to pay.

```bash
curl -i "https://aayatai.com/repo/tree?owner=honojs&repo=hono&ref=main&path=.github%2Fworkflows%2F"
```

## 2. Pay and call (TypeScript)

```bash
npm install @x402/fetch @x402/evm viem
```

```ts
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

// A wallet used only by your agent, holding a little USDC on Base.
const account = privateKeyToAccount(process.env.WALLET_PRIVATE_KEY as `0x${string}`);
const pay = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }],
});

const res = await pay("https://aayatai.com/repo/tree?owner=honojs&repo=hono&ref=main&path=.github%2Fworkflows%2F");
console.log(await res.json());
```

## 3. Or as an MCP tool

```ts
// MCP server: https://aayatai.com/mcp (Streamable HTTP). With the x402 MCP client (see /start):
const result = await client.callTool("repo-tree", {"owner":"honojs","repo":"hono","ref":"main","path":".github/workflows/"});
```

## Inputs

- `owner` **(required)** (string): GitHub user or organisation, e.g. honojs.
- `repo` **(required)** (string): Repository name, e.g. hono.
- `ref` (string; default `main`): Branch, tag or commit (default main; master is tried if main doesn't exist).
- `path` (string): Only files under this folder, e.g. src/ (optional).
- `detail` (string; one of `full`, `brief`; default `full`): brief = key fields only (same price)

Bad inputs are rejected with HTTP 400 before any payment is asked for.

## Example answer

Example only: the shape of an answer, with placeholder addresses and made-up figures. It is not data about any real token or wallet; call the service (or its free sample) for real results.

```json
{
  "repo": "honojs/hono",
  "ref": "main",
  "files": [
    {
      "path": ".github/workflows/ci.yml",
      "bytes": 7059
    },
    {
      "path": ".github/workflows/no-response.yml",
      "bytes": 688
    },
    {
      "path": ".github/workflows/release.yml",
      "bytes": 467
    }
  ],
  "source": "File list from jsDelivr (mirrors public GitHub repositories)"
}
```
