## API base URL and authentication

- **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev`
- **Authentication:** send `x-api-key: sfk_...` on `/v1/**` and `/v2/**` routes unless the operation is explicitly anonymous (check OpenAPI `security`, the [API reference hub](https://www.socialfetch.dev/docs/api.mdx), [`/llms.txt`](https://www.socialfetch.dev/llms.txt), or [`/llms.json`](https://www.socialfetch.dev/llms.json) for each route).
- **OpenAPI JSON:** <https://www.socialfetch.dev/openapi.json>

- Outcome semantics such as `found`, `not_found`, and `private` are documented in [Errors](https://www.socialfetch.dev/docs/errors.mdx) and on operation pages when present in the OpenAPI contract.

## Markdown docs convention

- Every docs page has a markdown twin: append **`.mdx`** to the docs pathname (for example `/docs/quickstart` → `/docs/quickstart.mdx`).
- Agents that send `Accept: text/markdown` on `/docs/**` HTML URLs may receive markdown directly (same URL, `Vary: Accept`).
- Published blog posts use the same convention: `/blog/{slug}` → `/blog/{slug}.mdx`, or `Accept: text/markdown` on the HTML URL (`Vary: Accept`).

    - **productId** (required) — type `string`; nullable. Product id when the product record carries one.
    - **layout** (required) — type `string`; enum: product, landing. `product`: the normal product layout. `landing`: the creator replaced the storefront with a custom layout, so the extra details are not available; `landing` carries the OG tags instead.

      - _items:_
    - **payWhatYouWant** (required) — type `object`; nullable. The product's pay-what-you-want amounts; null when the product is not pay-what-you-want.
      - **suggestedAmount** (required) — type `integer`; minimum: 0; nullable. Suggested amount in the same unit as the product's `price.amount`; null when Gumroad sets none.
      - **defaultAmount** (required) — type `integer`; minimum: 0; nullable. Default amount in the same unit as the product's `price.amount`; null when Gumroad sets none.
    - **sellerReputation** (required) — type `object`; nullable. The creator's reputation; null when Gumroad omits it.

      - **name** (required) — type `string`; nullable. Collaborator's display name.
      - **url** (required) — type `string`; nullable. Collaborator's storefront URL.
      - **avatarUrl** (required) — type `string`; nullable. Collaborator's avatar URL.
      - **isVerified** (required) — type `boolean`; nullable. Whether Gumroad verified the collaborator.
    - **flags** (required) — type `object`. Small extra flags.
      - **isStreamOnly** (required) — type `boolean`; nullable. Whether the product is stream-only.

### Machine-readable error codes

When an error JSON body is returned, it may include one of these `error.code` values (derived from the OpenAPI schemas for this operation; additional codes may exist at runtime):

- `bad_request`

## Error handling & retries

Interpret HTTP status codes using the descriptions below. Do not assume a JSON body unless the OpenAPI schema defines one for that status.

- **400**: Invalid request **Retry:** Fix the request; retrying the same invalid payload will not help.
- **401**: Missing or invalid API key **Retry:** Fix the API key first; retrying without changes will not help.
- **402**: Insufficient credits **Retry:** Do not retry without resolving billing/credits (retrying the same request will not help).
- **500**: Unexpected or billing error
- **502**: Lookup could not be completed. **Retry:** May be transient; a few retries with backoff are reasonable.
- **503**: Service temporarily unavailable; safe to retry with backoff. **Retry:** Usually safe to retry with exponential backoff and jitter.

### Suggested client defaults

- Send the API key using the `x-api-key` header on every request.
- On `503` (and sometimes `502`), retry with backoff; cap retries and surface a clear error to the user.
- On `402`, surface an actionable billing message rather than blind retries.

## Examples

### TypeScript SDK

```typescript
import { SocialFetchClient } from "@socialfetch/sdk";

const client = new SocialFetchClient({
  apiKey: process.env.SOCIALFETCH_API_KEY!,
});

const result = await client.gumroad.getProductDetails({
  url: "https://meshhouse.gumroad.com/l/tracktools",
});

if (!result.ok) {
  console.error(result.error);
} else {
  console.log(result.value.data);
}
```

### Node.js

```javascript
const response = await fetch(
  "https://api.socialfetch.dev/v1/gumroad/product/details?url=https://meshhouse.gumroad.com/l/tracktools",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY"
    }
  }
);

const data = await response.json();
console.log(data);
```

### cURL

```bash
curl "https://api.socialfetch.dev/v1/gumroad/product/details?url=https://meshhouse.gumroad.com/l/tracktools" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
    "https://api.socialfetch.dev/v1/gumroad/product/details?url=https://meshhouse.gumroad.com/l/tracktools",
    headers={"x-api-key": "YOUR_API_KEY"},
)
data = response.json()
print(data)
```
