Parameters from the server's own tool schema.
Despite the financial context (x402 USDC payments), the tool itself performs only read operations—inspecting and returning endpoint metadata. The financial aspect is the payment mechanism for the service, not the tool's primary function. The tool does not execute code, modify data, delete anything, or move money; it solely queries and returns information about public endpoints.
From the tool's definition Tool description uses 'Inspect', 'Returns per-endpoint quote status', and explicitly states 'This deterministic endpoint does not call an upstream model.' It retrieves metadata about endpoints without modifying them.

Inspect up to 10 public x402 endpoints in one paid request, without paying the target endpoints. Returns per-endpoint quote status, schemes, amounts, network, asset, payTo, resource metadata, and aggregate buyer-readiness warnings. This deterministic endpoint does not call an upstream model. Pay up to $0.002 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_batch_quote_inspector accepts 5 parameters: body, urls, method, endpoints, 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_batch_quote_inspector: 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.
gpt55_x402_batch_quote_inspector is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gpt55_x402_batch_quote_inspector rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gpt55_x402_batch_quote_inspector. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gpt55_x402_batch_quote_inspector is provided by the GPT 5 5 x402 Low Cost Agent Tools MCP server (https://gpt55.558686.xyz/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
gpt55_x402_batch_quote_inspector is one line of GPT 5 5 x402 Low Cost Agent Tools's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
