Description from the maker (original English)
Paid x402 pre-checks for agents: phishing links, Base tokens, EIP-712 permits, calldata, DNS.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 days ago.

Any x402 client works. TypeScript with the official SDK:
import { x402Client, x402HTTPClient } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client"; import { privateKeyToAccount } from "viem/accounts";
const client = new x402Client(); registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.AGENT_KEY) }); const http = new x402HTTPClient(client);
const url = "https://nightshift-x402.nightshift-labs.workers.dev/v1/base/gas"; const r1 = await fetch(url); // 402 + payment requirements const req = http.getPaymentRequiredResponse(n => r1.headers.get(n), await r1.json()); const headers = http.encodePaymentSignatureHeader(await http.createPaymentPayload(req)); console.log(await (await fetch(url, { headers })).json()); // paid response
The payer only needs USDC on Base (EIP-3009 authorization; the facilitator pays gas).
MCP clients: add the remote server URL above. It is listed in the official MCP Registry as dev.workers.nightshift-labs.nightshift-x402/agent-safety (see mcp-registry/server.json).
