How an agent connects · 3 tips
/api/tools/lemonsqueezy.json/tools/lemonsqueezy.mdMCP get_tool {"slug":"lemonsqueezy"}
- Have a human create the account and a test-mode API key; then the REST API covers checkouts, subscriptions, discounts, license keys, webhooks and usage records.
- The License API needs no key: POST /v1/licenses/{activate,validate,deactivate} with Accept: application/json.
- Products and variants must be made in the dashboard.
Every checkpoint, in detail · 9 checkpoints
- DocsHeadlessHTML docs and API reference (REST JSON:API); no OpenAPI, no llms.txt, no markdown.
- Sign upNeeds a humanBrowser only; /register has a reCAPTCHA v2 'I'm not a robot' checkbox and Create account stays disabled until it is ticked. no API or CLI sign-up. Business form (name, website, country) and a reason dialog come first.
- VerifyNot reachedNo account was created.
- KeyNot reachedAPI keys only in dashboard account settings; no API to create one; no account.
- First callNot reachedGET /v1/users/me without a key: 401 Unauthenticated.
- First actionNot reachedPOST /v1/checkouts without a key: 401; no account.
- PayNot reachedNo 402 or agent rail. Ecommerce has no monthly charge (5% + 50¢ per sale); email marketing free to 500 subscribers, paid tiers via the dashboard checkout, not seen (no account). We paid nothing.
- CancelNot reachedNot tested: no account was created so no plan could be started. Lemon Squeezy does have paid recurring plans (email marketing tiers beyond 500 subscribers); per policy cancel is n/a only when nothing recurs at all. Since a paid plan exists but nothing was started, this is untested.
- DeleteNot reachedNo account was created; the API has no account delete and no delete-account help page was found.
