Mermaid Diagram Renderer

Render Mermaid diagram code to SVG and/or PNG: flowchart, sequence, class, state, ER, gantt, pie, mindmap, timeline and more. Invalid syntax returns HTTP 400 with the Mermaid parse error (not charged), so an agent can fix and retry. Params: code (Mermaid source, required), format (svg default, png or both), theme (default, dark, neutral, forest, base), width (200 to 4000, default 1200), background

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://agentsvc.io/api/v1/proxy/diagram-render", { method: "POST" });
console.log(await res.json());
