What is Token Price X402?

Token Price X402 is an MCP server that provides real-time cryptocurrency prices from CoinGecko, including price, 24h change, market cap, and volume. It supports 10,000+ tokens and uses the x402 micropayment protocol (USDC on Base L2) for pay-per-call access — no API key, no signup, and no rate-limit wall. It is part of the klymax402 marketplace of x402 micropayment APIs for AI agents.

How to use Token Price X402?

Add the server to your MCP client configuration (e.g., Claude Desktop, Cursor, ElizaOS) using the URL https://token-price.api.klymax402.com/mcp. For direct HTTP access, send a POST request to /api/price with a JSON body containing the token name; an x402-aware client automatically handles the 402 payment challenge and retry cycle.

常见问题

1

What tokens are supported?

Token Price X402 supports over 10,000 tokens by CoinGecko ID (e.g., bitcoin, ethereum, solana, dogecoin).

2

How does payment work?

Payments use the x402 protocol — an HTTP-native pay-per-call system. Each call costs $0.001 in USDC on Base L2 (network `eip155:8453`). No sign-up or API key is required; any x402-aware client handles the payment challenge automatically.

3

What data does the API return?

The API returns the current price in the requested currency, 24-hour price change percentage, market capitalization in USD, and 24-hour trading volume in USD, along with the token and currency identifiers.

4

What are the runtime requirements?

For MCP clients, only the server URL is needed. For HTTP access, an x402-aware client (such as `@x402/fetch`, `x402-agent-tools`, or ATXP) is required to handle the 402 payment challenge.

5

What is this server not for?

This server is not for stock prices, token safety checks, historical OHLCV data, or currency conversion. (Separate tools exist for those purposes in the klymax402 marketplace.)
