# How to connect Diffbot to Hermes Agent (paste one key, 35 tools) > Connect Diffbot to Hermes with ClawLink: paste your Diffbot key once and 35 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/diffbot Most guides for giving Hermes Agent Diffbot access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical Diffbot setup: pair once in the browser and your always-on Hermes agent can act on Diffbot for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself. ## Setup It takes three steps to connect Hermes to Diffbot. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Diffbot** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask Hermes Agent in plain English. **Paste this into Hermes to set up ClawLink:** > Set up ClawLink for Hermes and tell me when it's ready. > 1. Install the plugin: `hermes plugins install ClawLink-HQ/hermes-plugin --enable` > 2. Start pairing with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait. > 3. I'll approve it in my browser, then reply "approved". > 4. When I say approved, finish setup: `hermes clawlink finish` > 5. Then run `hermes clawlink test` and tell me whether ClawLink is ready. **Alternative for any agent (no plugin needed):** if the Hermes Agent plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect diffbot # connect Diffbot (browser OAuth) npx -y @useclawlink/cli actions diffbot # list available actions npx -y @useclawlink/cli run diffbot --input '' # execute (add --confirm for writes) ``` ### Install by command The prompt above walks Hermes through this. By hand, it is four commands and a browser approval: ```bash hermes plugins install ClawLink-HQ/hermes-plugin --enable hermes clawlink begin # prints an approval link — open it and approve hermes clawlink finish # after approving in the browser hermes clawlink test ``` Then connect Diffbot in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Diffbot API key once. Verify the connection by asking Hermes: > Use Diffbot to combine entity profiles and walk me through the result in plain English. ### Using a different agent? The Hermes plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Diffbot is connected in the dashboard, that agent calls the same 35 Diffbot tools over MCP.

ClawLink connects Diffbot to Hermes Agent and exposes 35 Diffbot tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using OpenClaw instead? The [OpenClaw Diffbot integration](https://claw-link.dev/openclaw/diffbot) works the same way. ## What the Hermes Agent Diffbot integration can do 35 Diffbot tools are ready for Hermes Agent once the account is connected. The 30 below are the ones people reach for most; your agent can call all 35. ### 30 of 35 Diffbot tools for Hermes | Tool | What it does | |---|---| | **Combine entity profiles** `diffbot_combine_entity_profiles` | Combine multiple entity profiles into a unified view using the Diffbot Knowledge Graph | | **Download bulk results** `diffbot_download_bulk_results` | Download results of a bulk enhance job with filtering options via POST request | | **Enhance entity** `diffbot_enhance_entity` | Enrich a person or organization with comprehensive data from the Diffbot Knowledge Graph | | **Extract job** `diffbot_extract_job` | Extract structured job posting data from job listing pages | | **Extract list** `diffbot_extract_list` | Extract structured data from list-style pages like news indexes, product listings, and | | **Get account** `diffbot_get_account` | Retrieves comprehensive Diffbot account information including subscription plan details, credit | | **Get analyze** `diffbot_get_analyze` | Automatically analyzes a web page to determine its type and extract structured data | | **Get article** `diffbot_get_article` | Extract information from articles, including authors, publication dates, and images | | **Get bulk data** `diffbot_get_bulk_data` | Download extracted results from a completed bulk job | | **Get bulk job status** `diffbot_get_bulk_job_status` | Poll the status of a specific Diffbot Knowledge Graph Enhance bulk job | | **Get bulk results** `diffbot_get_bulk_results` | Download the results of a completed Enhance Bulkjob | | **Get bulk single result** `diffbot_get_bulk_single_result` | Download the result of a single job within a Diffbot bulk enhance job | | **Get crawl data** `diffbot_get_crawl_data` | Download extracted results from a completed crawl job | | **Get discussion** `diffbot_get_discussion` | Extract structured discussion threads from web pages including forums, comment sections | | **Get event** `diffbot_get_event` | Extract event details from web pages | | **Get image** `diffbot_get_image` | Extract detailed information about images, including dimensions and recognition data | | **Get kg coverage report by ID** `diffbot_get_kg_coverage_report_by_id` | Download Knowledge Graph coverage report by report ID | | **Get product** `diffbot_get_product` | Extract product information such as specifications, prices, availability, and reviews | | **Get video** `diffbot_get_video` | Extract information from videos, including titles, descriptions, and embedded HTML | | **List bulk jobs** `diffbot_list_bulk_jobs` | List all Bulk jobs associated with a specific token | | **List bulk jobs status for token** `diffbot_list_bulk_jobs_status_for_token` | Get the status of all bulk enhance jobs for a token | | **List custom apis** `diffbot_list_custom_apis` | Retrieve all Custom APIs and their extraction rules currently defined on your Diffbot token | | **Resolve lost ID** `diffbot_resolve_lost_id` | Resolve lost IDs in the Knowledge Graph | | **Search** `diffbot_search` | Search the Diffbot Knowledge Graph using DQL (Diffbot Query Language) | | **Search crawl data** `diffbot_search_crawl_data` | Query crawl job collections using DQL (Diffbot Query Language) | | **Create bulk** `diffbot_create_bulk` | Submit a bulk extract job to process multiple URLs with Extract APIs | | **Create custom API** `diffbot_create_custom_api` | Create or update the parameters and ruleset of a Custom API | | **Create kg bulk enhance** `diffbot_create_kg_bulk_enhance` | Submit a bulk enhance job to enrich multiple entities asynchronously | | **Start bulk** `diffbot_start_bulk` | Start a Bulk Extract job | | **Start crawl** `diffbot_start_crawl` | Initiates a Diffbot crawl job that spiders a website starting from seed URLs and processes | ## Example prompts **Combine Entity Profiles** > Use Diffbot to combine entity profiles and walk me through the result in plain English. **Download Bulk Results** > Use Diffbot to download bulk results and walk me through the result in plain English. **Enhance Entity** > Use Diffbot to enhance entity and walk me through the result in plain English. **Extract Job** > Use Diffbot to extract job and walk me through the result in plain English. ## ClawLink vs. building it yourself The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Diffbot working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Diffbot API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Diffbot account becomes available to the agent without you building credential management. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Diffbot. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. | | **Agent usability** | You still need to expose the right Diffbot actions to the runtime in a format your agent can reliably use. | 35 tools for Diffbot are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Diffbot to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for Hermes Agent users instead. You install the plugin once, connect Diffbot in the browser, and the 35 tools above work from chat. There is no SDK and no config file, and the Diffbot key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`. ### Connection succeeds but no tools appear Reconnect Diffbot from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded. ### "Tool schema not loaded yet" error when calling Diffbot tools Diffbot tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Diffbot call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again. ### Diffbot returns 403 or "permission denied" on one action while others work Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs. ### API key setup works but results look incomplete Double-check that the API key for Diffbot has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a Hermes Agent Diffbot integration? Yes. ClawLink is the fastest way to connect Hermes to Diffbot: link your Diffbot account once in the browser and Hermes Agent can call the Diffbot API through 35 ready-made tools — no custom code or token handling. ### How do I connect Diffbot to Hermes with ClawLink? Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect Diffbot in the dashboard and Hermes can use it from the next message — no config files, and the Diffbot key you paste is stored server-side instead of in your environment. ### How long does it take to connect Diffbot to Hermes Agent? About two minutes. Sign in, click Connect next to Diffbot in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Diffbot up myself? The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Diffbot working from chat. ### Hermes paired but still can't use Diffbot Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link.
