You can scrape pages, search the web, run built-in or custom AI commands, and send AI prompts with full page context — all through a single REST endpoint.\r\n\r\n## Prerequisites\r\n\r\nThe user **must** have:\r\n1. **HARPA AI Chrome Extension** installed from https://harpa.ai\r\n2. **At least one active Node** — a browser with HARPA running (configured in the extension's AUTOMATE tab)\r\n3. **A HARPA API key** — obtained from the HARPA extension AUTOMATE tab. The key is provided as the `HARPA_API_KEY` environment variable.\r\n\r\nIf the user hasn't set up HARPA yet, direct them to: https://harpa.ai/grid/browser-automation-node-setup\r\n\r\n## API Reference\r\n\r\n**Endpoint:** `POST https://api.harpa.ai/api/v1/grid`\r\n**Auth:** `Authorization: Bearer $HARPA_API_KEY`\r\n**Content-Type:** `application/json`\r\n\r\nFull reference: https://harpa.ai/grid/grid-rest-api-reference\r\n\r\n---\r\n\r\n## Actions\r\n\r\n### 1. Scrape a Web Page\r\n\r\nExtract full page content (as markdown) or specific elements via CSS/XPath/text selectors.\r\n\r\n**Full page scrape:**\r\n\r\n```bash\r\ncurl -s -X POST https://api.harpa.ai/api/v1/grid \\\r\n  -H \"Authorization: Bearer $HARPA_API_KEY\" \\\r\n  -H \"Content-Type: application/json\" \\\r\n  -d '{\r\n    \"action\": \"scrape\",\r\n    \"url\": \"https://example.com\",\r\n    \"timeout\": 15000\r\n  }'\r\n```\r\n\r\n**Targeted element scrape (grab):**\r\n\r\n```bash\r\ncurl -s -X POST https://api.harpa.ai/api/v1/grid \\\r\n  -H \"Authorization: Bearer $HARPA_API_KEY\" \\\r\n  -H \"Content-Type: application/json\" \\\r\n  -d '{\r\n    \"action\": \"scrape\",\r\n    \"url\": \"https://example.com/products\",\r\n    \"grab\": [\r\n      {\r\n        \"selector\": \".product-title\",\r\n        \"selectorType\": \"css\",\r\n        \"at\": \"all\",\r\n        \"take\": \"innerText\",\r\n        \"label\": \"titles\"\r\n      },\r\n      {\r\n        \"selector\": \".product-price\",\r\n        \"selectorType\": \"css\",\r\n        \"at\": \"all\",\r\n        \"take\": \"innerText\",\r\n        \"label\": \"prices\"\r\n      }\r\n    ],\r\n    \"timeout\": 15000\r\n  }'\r\n```\r\n\r\n**Grab fields:**\r\n\r\n| Field | Required | Default | Values |\r\n|-------|----------|---------|--------|\r\n| selector | yes | — | CSS (`.class`, `#id`), XPath (`//h2`), or text content |\r\n| selectorType | no | auto | `auto`, `css`, `xpath`, `text` |\r\n| at | no | first | `all`, `first`, `last`, or a number |\r\n| take | no | innerText | `innerText`, `textContent`, `innerHTML`, `outerHTML`, `href`, `value`, `id`, `className`, `attributes`, `styles`, `[attrName]`, `(styleName)` |\r\n| label | no | data | Custom label for extracted data |\r\n\r\n### 2. Search the Web (SERP)\r\n\r\nPerform a web search. Supports operators like `site:`, `intitle:`.\r\n\r\n```bash\r\ncurl -s -X POST https://api.harpa.ai/api/v1/grid \\\r\n  -H \"Authorization: Bearer $HARPA_API_KEY\" \\\r\n  -H \"Content-Type: application/json\" \\\r\n  -d '{\r\n    \"action\": \"serp\",\r\n    \"query\": \"OpenClaw AI agent framework\",\r\n    \"timeout\": 15000\r\n  }'\r\n```\r\n\r\n### 3. Run an AI Command\r\n\r\nExecute one of 100+ built-in HARPA commands or a custom automation on a target page.\r\n\r\n```bash\r\ncurl -s -X POST https://api.harpa.ai/api/v1/grid \\\r\n  -H \"Authorization: Bearer $HARPA_API_KEY\" \\\r\n  -H \"Content-Type: application/json\" \\\r\n  -d '{\r\n    \"action\": \"command\",\r\n    \"url\": \"https://example.com/article\",\r\n    \"name\": \"Extract data\",\r\n    \"inputs\": \"List all headings with their word counts\",\r\n    \"connection\": \"HARPA AI\",\r\n    \"resultParam\": \"message\",\r\n    \"timeout\": 30000\r\n  }'\r\n```\r\n\r\n- `name` — command name (e.g. `\"Summary\"`, `\"Extract data\"`, or any custom command)\r\n- `inputs` — pre-filled user inputs for multi-step commands\r\n- `resultParam` — HARPA parameter to return as result (default: `\"message\"`)\r\n- `connection` — AI model to use (e.g. `\"HARPA AI\"`, `\"gpt-4o\"`, `\"claude-3.5-sonnet\"`)\r\n\r\n### 4. Run an AI Prompt\r\n\r\nSend a custom AI prompt with page context. Use `{{page}}` to inject the page content.\r\n\r\n```bash\r\ncurl -s -X POST https://api.harpa.ai/api/v1/grid \\\r\n  -H \"Authorization: Bearer $HARPA_API_KEY\" \\\r\n  -H \"Content-Type: application/json\" \\\r\n  -d '{\r\n    \"action\": \"prompt\",\r\n    \"url\": \"https://example.com\",\r\n    \"prompt\": \"Analyze the current page and extract all contact information. Webpage: {{page}}\",\r\n    \"connection\": \"CHAT AUTO\",\r\n    \"timeout\": 30000\r\n  }'\r\n```\r\n\r\n---\r\n\r\n## Common Parameters\r\n\r\n| Parameter | Required | Default | Description |\r\n|-----------|----------|---------|-------------|\r\n| action | yes | — | `scrape`, `serp`, `command`, or `prompt` |\r\n| url | no | — | Target page URL (ignored by `serp`) |\r\n| node | no | — | Node ID (`\"r2d2\"`), multiple (`\"r2d2 c3po\"`), first N (`\"5\"`), or all (`\"*\"`) |\r\n| timeout | no | 300000 | Max wait time in ms (max 5 minutes) |\r\n| resultsWebhook | no | — | URL to POST results to asynchronously (retained 30 days) |\r\n| connection | no | — | AI model for `command`/`prompt` actions |\r\n\r\n## Node Targeting\r\n\r\n- Omit `node` to use the default node\r\n- `\"node\": \"mynode\"` — target a specific node by ID\r\n- `\"node\": \"node1 node2\"` — target multiple nodes\r\n- `\"node\": \"3\"` — use first 3 available nodes\r\n- `\"node\": \"*\"` — broadcast to all nodes\r\n\r\n## Async Results via Webhook\r\n\r\nSet `resultsWebhook` to receive results asynchronously. The action stays alive for up to 30 days, useful when target nodes are temporarily offline.\r\n\r\n```json\r\n{\r\n  \"action\": \"scrape\",\r\n  \"url\": \"https://example.com\",\r\n  \"resultsWebhook\": \"https://your-server.com/webhook\",\r\n  \"timeout\": 15000\r\n}\r\n```\r\n\r\n## Tips\r\n\r\n- Scraping behind-login pages works because HARPA runs inside a real browser session with the user's cookies and auth state.\r\n- Use the `grab` array with multiple selectors to extract structured data in a single request.\r\n- For long-running AI commands, increase `timeout` (max 300000ms / 5 min) or use `resultsWebhook`.\r\n- The `{{page}}` variable in prompts injects the full page content — use it to give AI context about the current page.\r\n","readmeExcerpt":"--- name: harpa-grid description: Automate web browsers, scrape pages, search the web, and run AI prompts on live websites via HARPA AI Grid REST API user-invocable: true homepage: https://harpa.ai/grid/web-automation metadata: {\"openclaw\":{\"emoji\":\"🌐\",\"requires\":{\"anyBins\":[\"curl\",\"wget\"],\"env\":[\"HARPA_API_KEY\"]},\"primaryEnv\":\"HARPA_API_KEY\",\"homepage\":\"https://harpa.ai/grid/web-automation\",\"skillKey\":\"harpa-grid\"}","codeSnippets":[],"executableExamples":[],"parameters":{},"dependencies":[],"permissions":[],"extractedFiles":[],"languages":["typescript"],"docsSourceLabel":"CLAWHUB","editorialOverview":"Automate web browsers, scrape pages, search the web, and run AI prompts on live websites via HARPA AI Grid REST API --- name: harpa-grid description: Automate web browsers, scrape pages, search the web, and run AI prompts on live websites via HARPA AI Grid REST API user-invocable: true homepage: https://harpa.ai/grid/web-automation metadata: {\"openclaw\":{\"emoji\":\"🌐\",\"requires\":{\"anyBins\":[\"curl\",\"wget\"],\"env\":[\"HARPA_API_KEY\"]},\"primaryEnv\":\"HARPA_API_KEY\",\"homepage\":\"https://harpa.ai/grid/web-automation\",\"skillKey\":\"harpa-grid\"}","editorialQuality":{"score":100,"threshold":65,"status":"ready","wordCount":382,"uniquenessScore":63,"reasons":[]}},"media":{"evidence":{"source":"no-media","verified":false,"confidence":"low","updatedAt":"2026-04-15T00:45:39.800Z","emptyReason":"No screenshots, media assets, or demo links are available."},"primaryImageUrl":null,"mediaAssetCount":0,"assets":[],"demoUrl":null},"ownerResources":{"evidence":{"source":"unclaimed","verified":false,"confidence":"low","updatedAt":"2026-04-15T00:45:39.800Z","emptyReason":"This page has not been claimed by the agent owner."},"hasCustomPage":false,"customPageUpdatedAt":null,"customLinks":[],"structuredLinks":{"docsUrl":null,"demoUrl":null,"supportUrl":null,"pricingUrl":null,"statusUrl":null},"customPage":null},"relatedAgents":{"evidence":{"source":"protocol-neighbors","verified":false,"confidence":"medium","updatedAt":"2026-10-10T09:08:22.877Z","emptyReason":null},"items":[{"id":"8ebccd8e-3863-4187-8355-c3f14e1f9edf","entityType":"agent","canonicalPath":"/agent/iofficeai-aionui","slug":"iofficeai-aionui","name":"AionUi","description":"Free, local, open-source 24/7 Cowork app and OpenClaw for Gemini CLI, Claude Code, Codex, OpenCode, Qwen Code, Goose CLI, Auggie, and more | 🌟 Star if you like it!","url":"https://github.com/iOfficeAI/AionUi","homepage":"https://www.aionui.com","source":"GITHUB_REPOS","protocols":["MCP","OPENCLAW"],"capabilities":[],"safetyScore":100,"overallRank":70,"updatedAt":"2026-10-09T19:11:12.944Z","createdAt":"2026-02-25T03:38:16.584Z","downloads":null},{"id":"b917f68a-ebff-438e-84f8-3f4b2494c0bc","entityType":"agent","canonicalPath":"/agent/activepieces-activepieces","slug":"activepieces-activepieces","name":"activepieces","description":"AI Agents & MCPs & AI Workflow Automation • (~400 MCP servers for AI agents) • AI Automation / AI Agent with MCPs • AI Workflows & AI Agents • MCPs for AI Agents","url":"https://github.com/activepieces/activepieces","homepage":"https://www.activepieces.com","source":"GITHUB_REPOS","protocols":["OPENCLAW"],"capabilities":[],"safetyScore":100,"overallRank":70,"updatedAt":"2026-04-15T02:22:12.426Z","createdAt":"2026-02-25T03:38:12.412Z","downloads":null},{"id":"5cb26759-3a39-483f-94cf-276a98c13bb8","entityType":"agent","canonicalPath":"/agent/cherryhq-cherry-studio","slug":"cherryhq-cherry-studio","name":"cherry-studio","description":"AI productivity studio with smart chat, autonomous agents, and 300+ assistants.
