# Send Gumroad to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "gumroad", "name": "Gumroad", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/byungkyu/gumroad", "canonicalUrl": "https://clawhub.ai/byungkyu/gumroad", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/gumroad", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=gumroad", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "LICENSE.txt" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "gumroad", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-04T00:20:19.251Z", "expiresAt": "2026-05-11T00:20:19.251Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=gumroad", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=gumroad", "contentDisposition": "attachment; filename=\"gumroad-1.0.4.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "gumroad" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/gumroad" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/gumroad", "downloadUrl": "https://openagent3.xyz/downloads/gumroad", "agentUrl": "https://openagent3.xyz/skills/gumroad/agent", "manifestUrl": "https://openagent3.xyz/skills/gumroad/agent.json", "briefUrl": "https://openagent3.xyz/skills/gumroad/agent.md" } } ``` ## Documentation ### Gumroad Access the Gumroad API with managed OAuth authentication. Manage products, view sales, verify licenses, and set up webhooks for your digital storefront. ### Quick Start # Get current user info python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/gumroad/v2/user') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ### Base URL https://gateway.maton.ai/gumroad/v2/{resource} The gateway proxies requests to api.gumroad.com/v2 and automatically injects your OAuth token. ### Authentication All requests require the Maton API key in the Authorization header: Authorization: Bearer $MATON_API_KEY Environment Variable: Set your API key as MATON_API_KEY: export MATON_API_KEY="YOUR_API_KEY" ### Getting Your API Key Sign in or create an account at maton.ai Go to maton.ai/settings Copy your API key ### Connection Management Manage your Gumroad OAuth connections at https://ctrl.maton.ai. ### List Connections python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections?app=gumroad&status=ACTIVE') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ### Create Connection python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'gumroad'}).encode() req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Content-Type', 'application/json') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ### Get Connection python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF Response: { "connection": { "connection_id": "e1a4444f-2bb8-4e09-9265-3afe71b74b1f", "status": "ACTIVE", "creation_time": "2026-02-08T06:22:48.654579Z", "last_updated_time": "2026-02-08T06:23:07.420381Z", "url": "https://connect.maton.ai/?session_token=...", "app": "gumroad", "metadata": {} } } Open the returned url in a browser to complete OAuth authorization. ### Delete Connection python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ### Specifying Connection If you have multiple Gumroad connections, specify which one to use with the Maton-Connection header: python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/gumroad/v2/products') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', 'e1a4444f-2bb8-4e09-9265-3afe71b74b1f') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF If omitted, the gateway uses the default (oldest) active connection. ### User Info Get Current User GET /gumroad/v2/user Response: { "success": true, "user": { "name": "Chris", "currency_type": "usd", "bio": null, "twitter_handle": null, "id": "1690942847664", "user_id": "QmTtTnViFSoocHAexgLuJw==", "url": "https://chriswave1246.gumroad.com", "profile_url": "https://public-files.gumroad.com/...", "email": "chris@example.com", "display_name": "Chris" } } ### Product Operations List Products GET /gumroad/v2/products Response: { "success": true, "products": [ { "id": "ABC123", "name": "My Product", "price": 500, "currency": "usd", "short_url": "https://gumroad.com/l/abc", "sales_count": 10, "sales_usd_cents": 5000 } ] } Get Product GET /gumroad/v2/products/{product_id} Update Product PUT /gumroad/v2/products/{product_id} Content-Type: application/x-www-form-urlencoded name=Updated%20Name&price=1000 Enable/Disable Product PUT /gumroad/v2/products/{product_id}/disable Content-Type: application/x-www-form-urlencoded disabled=true Delete Product DELETE /gumroad/v2/products/{product_id} Note: Creating new products via API is not supported.
