## Getting Your Stripe API Key

<details>
<summary><strong>Steps</strong></summary>

1. Go to [Stripe Dashboard](https://dashboard.stripe.com)
2. Click **Developers** in the top navigation
3. Select **API keys** from the left sidebar

## Troubleshooting

<details>
<summary><strong>Missing or Invalid Headers</strong></summary>

- **Cause:** API key not provided in request headers or incorrect format
- **Solution:**
  1. Verify `Authorization: Bearer YOUR_API_KEY` and `X-Mewcp-Credential-Id: CREDENTIAL-ID` headers are present
  2. Check API key is active in your MewCP account

</details>

<details>
<summary><strong>Insufficient Credits</strong></summary>

- **Cause:** API calls have exceeded your request limits
- **Solution:**
  1. Check credit usage in your Curious Layer dashboard
  2. Upgrade to a paid plan or add credits for higher limits
  3. Contact support for credit adjustments

</details>

<details>
<summary><strong>Credential Not Connected</strong></summary>

- **Cause:** No Stripe credential linked to your account
- **Solution:**
  1. Go to **Credentials** in your MewCP dashboard
  2. Add your Stripe API key (static auth)
  3. Retry the request with the correct `X-Mewcp-Credential-Id` header

</details>

<details>
<summary><strong>Malformed Request Payload</strong></summary>

- **Cause:** JSON payload is invalid or missing required fields
- **Solution:**
  1. Validate JSON syntax before sending
  2. Ensure all required tool parameters are included
  3. Check parameter types match expected values

</details>

<details>
<summary><strong>Server Not Found</strong></summary>

- **Cause:** Incorrect server name in the API endpoint
- **Solution:**
  1. Verify endpoint format: `{server-name}/mcp/{tool-name}`
  2. Use correct server name from documentation
  3. Check available servers in your Curious Layer account

</details>

<details>
<summary><strong>Stripe API Error</strong></summary>

- **Cause:** Upstream Stripe API returned an error
- **Solution:**
  1. Check Stripe service status at [Stripe Status Page](https://status.stripe.com)
  2. Verify your API key has the required permissions (live vs. test mode)
  3. Review the error message for specific details — Stripe errors are descriptive
