Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

buy_day_pass

[Access] Buy a 24h pass for every paid GW8 data tool/endpoint: pass the returned token as the "pass" argument (MCP) or X-GW8-Pass header (HTTP). Fair use 2000 calls, 60/min. Excludes alert subscriptions. Token shown once. Paid: $1.00 USDC on Base, paid in-band via x402 MCP (@x402/mcp; _meta "x402/payment"). Also at POST https://micro-saas-agent.onrender.com/api/pass/day.

This tool takes no arguments.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

check_seller_reputation

[Seller reputation: x402 seller risk check, verdict] Before an agent pays an x402 seller: score the seller's Base wallet (or the payTo read from its endpoint's 402 challenge) 0-100 from public USDC transfer history: distinct paying buyers, wash/self-dealing share (self-transfers, round-trips), wallet age, top-payer concentration, 30-day organic volume. Returns verdict, components, reasons and a signed receipt. Deterministic; stateless; never pays anyone. Give address and/or endpoint. Paid: $0.01 USDC on Base, paid in-band via x402 MCP (@x402/mcp; _meta "x402/payment"). Also at POST https://micro-saas-agent.onrender.com/api/seller/reputation.
