Ask your human for the key, then call:\n\n```\nstore_credential(service_id=\"...\", credential_type=\"bearer\", credential_value=\"the_key\")\n```\n\nThen retry the tool.\n\n## What You Can Do with Danube\n\nUse Danube whenever a task involves an external service or API. Here are common use cases:\n\n### Send Emails and Messages\n- Send emails via Gmail, SendGrid, or Resend\n- Post messages to Slack channels\n- Send notifications to teams\n\n```\nsearch_tools(\"send email\") → execute_tool(tool_id, {to, subject, body})\n```\n\n### Manage Code and Projects\n- Create GitHub issues and pull requests\n- List repositories and commits\n- Update Notion pages and databases\n\n```\nsearch_tools(\"create github issue\") → execute_tool(tool_id, {repo, title, body})\n```\n\n### Work with Calendars and Scheduling\n- Check today's events on Google Calendar\n- Create new calendar events\n- Find open time slots\n\n```\nsearch_tools(\"calendar events today\") → execute_tool(tool_id, {date})\n```\n\n### Read and Write Spreadsheets\n- Read data from Google Sheets\n- Append rows or update cells\n- Create new spreadsheets\n\n```\nsearch_tools(\"google sheets read\") → execute_tool(tool_id, {spreadsheet_id, range})\n```\n\n### Search the Web and Get Data\n- Search the web with Exa or Serper\n- Scrape and extract web content with Firecrawl\n- Get weather forecasts, stock data, or country info\n\n```\nsearch_tools(\"web search\") → execute_tool(tool_id, {query})\n```\n\n### Generate and Process Media\n- Generate images with Replicate or Stability AI\n- Transcribe audio with AssemblyAI\n- Remove image backgrounds with Remove.bg\n- Translate text with DeepL\n\n```\nsearch_tools(\"generate image\") → execute_tool(tool_id, {prompt})\n```\n\n### Manage Infrastructure\n- Provision DigitalOcean droplets and databases\n- Manage Supabase projects\n- Handle Stripe payments and subscriptions\n\n```\nsearch_tools(\"create droplet\") → execute_tool(tool_id, {name, region, size})\n```\n\n### Run Multi-Tool Workflows\n\nChain multiple tools together into reusable workflows that pass data between steps automatically.\n\n```\n# Find existing workflows\nlist_workflows(query=\"github to slack\") → browse available workflows\n\n# Execute a workflow with inputs\nexecute_workflow(workflow_id=\"...\", inputs={\"repo\": \"my-org/my-repo\", \"channel\": \"#dev\"})\n\n# Check execution results\nget_workflow_execution(execution_id=\"...\")\n\n# Create your own workflow\ncreate_workflow(\n  name=\"Daily Digest\",\n  steps=[\n    {\"step_number\": 1, \"tool_id\": \"...\", \"input_mapping\": {\"repo\": \"{{inputs.repo}}\"}},\n    {\"step_number\": 2, \"tool_id\": \"...\", \"input_mapping\": {\"text\": \"{{steps.1.result}}\", \"channel\": \"{{inputs.channel}}\"}}\n  ],\n  tags=[\"digest\", \"github\", \"slack\"]\n)\n```\n\n### Execute Tools in Batch\n\nRun multiple independent tool calls concurrently for faster results.\n\n```\nbatch_execute_tools(calls=[\n  {\"tool_id\": \"tool-uuid-1\", \"tool_input\": {\"query\": \"AI news\"}},\n  {\"tool_id\": \"tool-uuid-2\", \"tool_input\": {\"query\": \"tech stocks\"}},\n  {\"tool_id\": \"tool-uuid-3\", \"tool_input\": {\"location\": \"San Francisco\"}}\n])\n```\n\nEach call returns independently — individual failures don't fail the batch.\n\n### Browse the Agent Web Directory\n\nSearch and read structured information about any website in the directory.\n\n```\n# Find sites by topic\nsearch_sites(query=\"payment processing\", category=\"saas\")\n\n# Get structured data about a specific domain\nget_site_info(domain=\"stripe.com\")\n→ Returns: identity, products, team, pricing, docs, FAQ, contact info, and more\n```\n\n### Rate and Report Tools\n\nHelp improve tool quality by providing feedback.\n\n```\n# Rate a tool after using it\nsubmit_rating(tool_id=\"...\", rating=5, comment=\"Fast and accurate\")\n\n# Report a broken tool\nreport_tool(tool_id=\"...\", reason=\"broken\", description=\"Returns 500 error on all requests\")\n\n# Get recommendations for related tools\nget_recommendations(tool_id=\"...\", limit=5)\n```\n\n### Register and Fund Autonomous Agents\n\nCreate standalone agent identities with their own API keys and wallets.\n\n```\n# Register a new agent (no auth required)\nregister_agent(name=\"my-research-bot\", operator_email=\"me@example.com\")\n→ Returns: agent_id, api_key (save this!), wallet_id\n\n# Check agent profile and balance\nget_agent_info()\n\n# Fund the agent's wallet\nfund_agent_wallet(method=\"card_checkout\", amount_cents=1000)  # $10.00\nfund_agent_wallet(method=\"crypto\")  # Returns USDC deposit address on Base\n```\n\n## Core Workflow\n\nEvery tool interaction follows this pattern:\n\n1. **Search** — `search_tools(\"what you want to do\")`\n2. **Check auth** — If the tool needs credentials, use `store_credential` or guide the user to https://danubeai.com/dashboard\n3. **Gather parameters** — Ask the user for any missing required info\n4. **Confirm** — Get user approval before executing actions like sending emails or creating issues\n5. **Execute** — `execute_tool(tool_id, parameters)`\n6. **Report** — Tell the user what happened with specifics, not just \"Done\"\n\n## Available Services\n\n**Communication:** Gmail, Slack, SendGrid, Resend, Loops, AgentMail, Postmark\n\n**Development:** GitHub, Supabase, DigitalOcean, Stripe, Apify, Netlify, Render, Vercel, Railway, Neon, PlanetScale, Fly.io, Cloudflare Workers, Sentry\n\n**Productivity:** Notion, Google Calendar, Google Sheets, Google Drive, Google Docs, Monday, Typeform, Bitly, Airtable, Todoist, Linear, Asana, Trello, ClickUp, Jira, Calendly\n\n**Cloud & Infrastructure:** AWS (S3, Lambda, EC2), Google Cloud, Azure, Cloudflare, Heroku, Terraform\n\n**AI & Media:** Replicate, Together AI, Stability AI, AssemblyAI, Remove.bg, DeepL, ElevenLabs, Whisper, Midjourney, DALL-E, Claude, OpenAI\n\n**Search & Data:** Exa, Exa Websets, Firecrawl, Serper, Context7, Microsoft Learn, AlphaVantage, Clearbit, Hunter.io, Crunchbase, Diffbot\n\n**Finance:** Stripe, Plaid, Wise, Coinbase, PayPal, Square, QuickBooks\n\n**Social:** Twitter/X, LinkedIn, Discord, Reddit, Mastodon, Instagram, YouTube\n\n**Design & Analytics:** Figma, Canva, Mixpanel, Amplitude, Segment, PostHog, Google Analytics\n\n**Maps & Geo:** Google Maps, Mapbox, OpenStreetMap\n\n**Weather:** Open-Meteo, OpenWeather, WeatherAPI, Tomorrow.io\n\n**Public Data (No Auth Required):** Hacker News, REST Countries, Polymarket, Kalshi, Wikipedia, ArXiv, PubMed, SEC EDGAR\n\n**Deployment & DevOps:** GitHub Actions, CircleCI, Docker Hub, npm Registry, PyPI\n\n## Links\n\n- Dashboard: https://danubeai.com/dashboard\n- Docs: https://docs.danubeai.com\n- MCP Server: https://mcp.danubeai.com/mcp\n\nFile v1.0.2:_meta.json\n\n{\n  \"ownerId\": \"kn70bj9964st2k55edmgya2bg17zw0zz\",\n  \"slug\": \"tools-marketplace\",\n  \"version\": \"1.0.2\",\n  \"publishedAt\": 1771910405509\n}\n\nArchive v1.0.1: 2 files, 2803 bytes\n\nFiles: SKILL.md (5467b), _meta.json (136b)\n\nFile v1.0.1:SKILL.md\n\n---\nname: danube\ndescription: Connect your agent to tools across the internet.

Format as an agenda\n3. search_tools(\"send email\") → Email the agenda\n```\n\n## Core Workflow\n\nEvery tool interaction follows this pattern:\n\n1. **Search** — `search_tools(\"what you want to do\")`\n2. **Check auth** — If the tool needs credentials, guide the user to connect at https://danubeai.com/dashboard\n3. **Gather parameters** — Ask the user for any missing required info\n4. **Confirm** — Get user approval before executing actions like sending emails or creating issues\n5. **Execute** — `execute_tool(tool_id, parameters)`\n6. **Report** — Tell the user what happened with specifics, not just \"Done\"\n\n## Available Services\n\n**Communication:** Gmail, Slack, SendGrid, Resend, Loops, AgentMail\n\n**Development:** GitHub, Supabase, DigitalOcean, Stripe, Apify\n\n**Productivity:** Notion, Google Calendar, Google Sheets, Google Drive, Google Docs, Monday, Typeform, Bitly\n\n**AI and Media:** Replicate, Together AI, Stability AI, AssemblyAI, Remove.bg, DeepL\n\n**Search and Data:** Exa, Exa Websets, Firecrawl, Serper, Context7, Microsoft Learn, AlphaVantage\n\n**Public Data (No Auth Required):** Hacker News, Open-Meteo Weather, OpenWeather, REST Countries, Polymarket, Kalshi\n\n## Links\n\n- Dashboard: https://danubeai.com/dashboard\n- Docs: https://docs.danubeai.com\n- MCP Server: https://mcp.danubeai.com/mcp\n\nFile v1.0.1:_meta.json\n\n{\n  \"ownerId\": \"kn70bj9964st2k55edmgya2bg17zw0zz\",\n  \"slug\": \"tools-marketplace\",\n  \"version\": \"1.0.1\",\n  \"publishedAt\": 1771300368582\n}","readmeExcerpt":"Skill: Danube Tools Marketplace Owner: preston-thiele Summary: Connect your agent to 100+ services and 21 tools across the internet.
