Use it over MCP

The same tools are an MCP server, no auth: https://yruz.one/mcp/x402 (streamable HTTP, stateless). Payments follow the x402 MCP transport: an unpaid tools/call returns isError with the PaymentRequired in structuredContent; repeat it with the signed PaymentPayload in params._meta["x402/payment"]; the receipt comes back in result._meta["x402/payment-response"]. get_example is free. Listed in the official MCP Registry as io.github.xzntexe/yruz-x402. Server card: https://yruz.one/.well-known/mcp/x402-server-card.json.

Tools: site_audit, web_extract, company_enrich, url_safety_check, weather_forecast, link_preview, domain_intel, broken_links, uptime_check, x402_endpoint_check, wallet_balance, crypto_price, crypto_trending, solana_token_check, solana_portfolio, solana_tx_explain, network_fees, get_example. See examples/mcp-client.mjs.

Bad input is free

Every refused call (HTTP 400/404/422) is free and says how to succeed: charged: false, the endpoint, its parameters, a valid example call, the price and the docs. Unknown paths suggest the closest tool (/api/extractt -> /api/extract).

How to pay

1. Call any endpoint (GET with query parameters or POST with a JSON body). Unpaid, it answers HTTP 402.
2. x402 v2 clients read the base64 PAYMENT-REQUIRED header and resend with PAYMENT-SIGNATURE. x402 v1 clients read the JSON body (accepts) and resend with X-PAYMENT.
3. Every 402 offers Base (eip155:8453) and Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). The payment is bound to the exact input, so change nothing between the 402 and the paid retry.
4. Invalid or private input is refused with a free 400 before any payment. Receipts come back in PAYMENT-RESPONSE / X-PAYMENT-RESPONSE.
