Scan public x402 directories for a service URL, host, payTo, or query and return sampled first-seen positions, matched sources, price signals, competitor context, and concrete visibility fixes. This deterministic endpoint does not call an upstream model. Pay up to $0.01 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json. It is categorised as a Read tool in the GPT 5 5 x402 Low Cost Agent Tools MCP Server, which means it retrieves data without modifying state.
gpt55_x402_directory_rank_tracker accepts 12 parameters: url, host, name, limit, pages, payTo, query, pay_to, sources, base_url, page_size, timeout_ms. The full parameter table on this page comes from the server's own tool schema.
Register the GPT 5 5 x402 Low Cost Agent Tools MCP server in PolicyLayer and add a rule for gpt55_x402_directory_rank_tracker: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GPT 5 5 x402 Low Cost Agent Tools. Nothing to install.
