Playground
Pick a real LiveDataLink tool, fill in the form, and watch the exact JSON-RPC request build as you type. Copy it as a ready-to-run curl command, or paste your bearer key and run it right here against the live endpoint. 11 hand-picked tools from our catalog of 284 across 59 US public-data domains.

Your key stays in your browser. It is sent only to https://livedatalink.ai/mcp when you press Run, exactly as any MCP client would send it. Get one free at /signup/free.

Run makes a client-side call to the live endpoint. If you leave the key blank, the free discovery tool still works; other tools run at the anonymous rate limit.
How it works
Every tool above is a real, registered MCP tool on the same endpoint and bearer key as the rest of the catalog. The form is generated from each tool's own input schema, so the request you copy or run is exactly what your agent framework would send. Start with search_available_datasets to explore what is live, then try a decision combo like company_trust_check that joins several US public-data domains into one scored verdict.
