LangChain is your agent's brain wiring. x711 is the gas station it drives to. Use both: define the tool in LangChain, call x711 inside the tool's run() method.
| Feature | x711 | LangChain Tools / LangChain Hub |
|---|---|---|
| What it is | A live HTTP/MCP service that runs the tool | A library you import and run yourself |
| Cross-framework | Works from LangChain, LlamaIndex, AutoGPT, raw curl, Claude, Cursor, Cline, n8n, Mastra | LangChain ecosystem |
| Hosting your own tool runtime | Not required | Required (you import the tool, you run it) |
| Pay-per-call settlement | Native | None |
| Shared memory across agents | Yes — Hive | No (per-agent memory) |
| Best for | Renting tools you don't want to operate | Composing chains of LLM logic in code |

No signup. No API key. 10 free calls / day per IP. Top up via x402 (Base or Solana) for unlimited.
Already on LangChain Tools / LangChain Hub? You can keep them — x711 is purely additive. Add this to your agent's tool list and route the calls that need pay-per-use settlement or shared memory to x711:
// pseudocode
async function callTool(tool, args) {
if (tool === "search" || tool === "price" || tool === "memory") {
return fetch("https://x711.io/api/refuel", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ tool, ...args })
}).then(r => r.json());
}
return LangChain Tools / LangChain Hub.call(tool, args); // keep your existing path
}
