Execute Visor Public API workflows using JavaScript.

You can provide an async arrow function, or a plain async function body with statements and return. Do NOT use TypeScript syntax: no type annotations, interfaces, or generics. Do NOT construct raw HTTP paths. Use the typed visor methods. Add a brief opening comment about the overall goal so returned results are easier to interpret. Domain rules already enforced by the Public API still apply: - facet requests require an explicit facets selection. - non-count facet metrics require exactly one selected categorical facet. - collection limit remains capped at 100. - sold_within_days and snapshot_date should not be combined. - distance sorting and radius filtering require postal_code or latitude plus longitude. Operational limits: - One execute workflow can make up to 50 underlying public API requests. - Underlying requests still count against account Usage Tier rate limits and normal metering. - The MCP server serializes public API requests, paces them from observed rate-limit headers, and may retry bounded 429 responses when Retry-After fits inside the execute budget. - If more waiting is required, execute returns structured pause guidance with retry_after_seconds instead of sleeping indefinitely. Example: // Compare recent used Tacoma listings in California before checking trim facets. const response = await visor.listings.search({ make: ["Toyota"], model: ["Tacoma"], state: ["CA"], inventory_type: "used", limit: 5 }); const listings = response.data; const total = response.pagination.total; const facets = await visor.facets.count({ facets: ["trim"], make: ["Toyota"], model: ["Tacoma"], state: ["CA"], inventory_type: "used" }); return { total, listings, trims: facets.data.facets.trim };
