  <h2>Why pay if the code is public?</h2>
  <p>You do not have to. The repository is open and self-hosting is supported. The hosted charge is for the operated result: upstream polling, normalization, bounded probes, source-health reporting, schema repairs, and a ready HTTPS endpoint. A fork transfers those operating costs to you; it does not create an exclusive data advantage.</p>
  <p>Payments use x402 on Base USDC. An unpaid request returns the machine-readable payment requirements; there is no account or subscription flow.</p>
  <p>The hosted MCP endpoint is stateless Streamable HTTP for clients such as Claude, Cursor, and other MCP-compatible agents. The public <a href="https://github.com/dacode-dev/agent-context-api/blob/main/server.json">server descriptor</a> documents the endpoint, and the server is published in the <a href="https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.dacode-dev%2Fagent-context-api">official MCP Registry</a>; local stdio self-hosting remains available.</p>
  <h2>Try it</h2>
  <pre><code>curl -X POST https://agent-context-api-proxy.agent-context-proxy.workers.dev/v1/context-preflight \
  -H 'content-type: application/json' \
  -d '{"text":"const token = \"sk-example\";", "model":"claude-sonnet", "token_budget":1000}'</code></pre>
  <p class="note">The stable public endpoint is a free Cloudflare Worker proxy over the operated origin. The origin tunnel may rotate internally without changing the buyer URL; for durable use, self-host from the <a href="https://github.com/dacode-dev/agent-context-api">public repository</a>. No revenue is claimed until a settled payment is independently recorded.</p>
