How to connect Twelve Data to OpenClaw
Connect Twelve Data to OpenClaw with ClawLink: paste your Twelve Data key once and 97 tools work from chat. No MCP server to run, nothing stored on your machine.
Twelve DataAPI KEYMCPTwelve Data provides a comprehensive financial data API offering real-time and historical market data for stocks, forex, cryptocurrencies, ETFs, and indices.. Once connected, OpenClaw can read and act on Twelve Data from chat — pairing, token refresh, and tool wiring handled for you.
The usual route to Twelve Data access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical Twelve Data setup: install one ClawHub skill, connect Twelve Data in the browser, and OpenClaw can call real Twelve Data actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.
Copy this prompt into OpenClaw, or open the Twelve Data skill on ClawHub.
Before installing anything, inspect the ClawHub skill metadata and setup requirements.
If the skill asks you to install a third-party package or CLI, verify its source, maintainer, and package contents before running the install command.
Install the skill "Twelve Data" (hith3sh/twelve-data-workspace) from ClawHub only after those checks pass.
Skill page: https://clawhub.ai/hith3sh/twelve-data-workspace
Keep the work scoped to this skill only.
After install, help me finish setup from verified skill metadata.
Use only the metadata you can verify from ClawHub; do not invent missing requirements.
Ask before making any broader environment changes.Setup
It takes three steps to connect OpenClaw to Twelve Data.
1Install the plugin

Use it from chat
Ask OpenClaw: "What can you do with Twelve Data?"
Install by command
The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval:
openclaw plugins install clawhub:clawlink-pluginThen ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say done. Finally, connect Twelve Data in the ClawLink dashboard — paste your Twelve Data API key once.
Verify the connection by asking OpenClaw:
Use Twelve Data to cash flow and walk me through the result in plain English.
Using a different agent?
The OpenClaw 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:
npx -y @useclawlink/cli loginlogin opens the same browser approval and stores a credential locally. Once Twelve Data is connected in the dashboard, that agent calls the same 97 Twelve Data tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

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 OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Twelve Data working from chat.
| Manual | ClawLink | |
|---|---|---|
| Credential handling | Collect, validate, store, and rotate the Twelve Data API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Twelve Data 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 Twelve Data. | 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 Twelve Data actions to the runtime in a format your agent can reliably use. | 97 tools for Twelve Data are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Twelve Data 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 OpenClaw users instead. You install the plugin once, connect Twelve Data in the browser, and the 97 tools above work from chat. There is no SDK and no config file, and the Twelve Data key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting
OpenClaw installed the Twelve Data skill but can't call the tools
The ClawHub skill teaches OpenClaw about Twelve Data, but the calls run through the ClawLink plugin and your connected account. Make sure Twelve Data is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register.
Connection succeeds but no tools appear
Reconnect Twelve Data 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 Twelve Data tools
Twelve Data 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 Twelve Data 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.
Twelve Data 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 Twelve Data has the right scopes or account access. A valid key can still be too limited for some reads or writes.
