{"schema_version":"v1","name_for_human":"Listing Roast x402","name_for_model":"listing_roast_x402","description_for_human":"Paid x402 API for listing quality scoring, buyer-agent skip reasons, and x402 discoverability checks.","description_for_model":"Listing Roast x402 is a paid HTTP JSON API for x402, MCP, and agent-service builders. Use it when a builder needs a paid API listing quality score, buyer-agent skip reasons, x402 marketplace conversion feedback, or x402 service discoverability guidance before promotion. Protected routes require x402 payment in USDC on Base before JSON output is returned. Use GET https://listing-roast-x402-service-production.up.railway.app/api, GET https://listing-roast-x402-service-production.up.railway.app/api/v1, or GET https://listing-roast-x402-service-production.up.railway.app/v1 for a generic $0.001 paid x402 navigation route map with fallback quick score when an agent starts at /api, /api/v1, or /v1 first. Preferred first paid action: GET https://listing-roast-x402-service-production.up.railway.app/api/listing-roast for $0.001, max 1000 USDC units. Use GET https://listing-roast-x402-service-production.up.railway.app/api/agent-listing-conversion for agent service listing clarity, agent listing conversion score, and buyer-agent skip reasons. Use GET https://listing-roast-x402-service-production.up.railway.app/api/x402-site-audit for a cheap x402 site audit and paid API preflight. Use POST https://listing-roast-x402-service-production.up.railway.app/api/listing-roast only when the buyer wants the full $0.01 roast, rewrite, and stop-or-upgrade guidance. Use free GET https://listing-roast-x402-service-production.up.railway.app/api/pricing for the paid route price catalog, free GET https://listing-roast-x402-service-production.up.railway.app/api/find?q=<task> to choose one route, and free GET/POST https://listing-roast-x402-service-production.up.railway.app/api/route to rank local paid routes before spending. Do not call paid routes unless the buyer intends to pay; free discovery files are OpenAPI, x402 manifest, agent card, Agent Skills index, MCP metadata, llms.txt, examples, sample score, pricing, route finder, local route router, and pay-now JSON.","auth":{"type":"none"},"api":{"type":"openapi","url":"https://listing-roast-x402-service-production.up.railway.app/.well-known/openapi.json","is_user_authenticated":false},"legal_info_url":"https://listing-roast-x402-service-production.up.railway.app/","x_listing_roast":{"paymentProtocol":"x402","network":"eip155:8453","asset":"USDC","payNow":"https://listing-roast-x402-service-production.up.railway.app/api/pay-now","pricing":"https://listing-roast-x402-service-production.up.railway.app/api/pricing","find":"https://listing-roast-x402-service-production.up.railway.app/api/find","route":"https://listing-roast-x402-service-production.up.railway.app/api/route","x402Manifest":"https://listing-roast-x402-service-production.up.railway.app/x402.json","agentCard":"https://listing-roast-x402-service-production.up.railway.app/.well-known/agent-card.json","agentSkills":"https://listing-roast-x402-service-production.up.railway.app/.well-known/agent-skills/index.json","openApi":"https://listing-roast-x402-service-production.up.railway.app/.well-known/openapi.json","recommendedFirstPaidAction":{"route":"https://listing-roast-x402-service-production.up.railway.app/api/listing-roast","path":"/api/listing-roast","method":"GET","price":"$0.001","maxAmountRequired":"1000","command":"npx awal@2.8.0 x402 pay https://listing-roast-x402-service-production.up.railway.app/api/listing-roast \\\n  -X GET \\\n  --max-amount 1000","reason":"Use this first when a marketplace or Bazaar result points to Listing Roast; it is the already-indexed URL and the lowest-friction paid score."},"recommendedPaidSequence":[{"step":1,"use":"indexedQuickScore","action":{"route":"https://listing-roast-x402-service-production.up.railway.app/api/listing-roast","path":"/api/listing-roast","method":"GET","price":"$0.001","maxAmountRequired":"1000","command":"npx awal@2.8.0 x402 pay https://listing-roast-x402-service-production.up.railway.app/api/listing-roast \\\n  -X GET \\\n  --max-amount 1000","reason":"Use this first when a marketplace or Bazaar result points to Listing Roast; it is the already-indexed URL and the lowest-friction paid score."},"reason":"Start with the already-indexed $0.001 quick score so Bazaar-visible buyers can confirm fit with the lowest-friction paid action."},{"step":2,"use":"fullRoast","action":{"route":"https://listing-roast-x402-service-production.up.railway.app/api/listing-roast","path":"/api/listing-roast","method":"POST","price":"$0.01","maxAmountRequired":"10000","command":"npx awal@2.8.0 x402 pay https://listing-roast-x402-service-production.up.railway.app/api/listing-roast \\\n  -X POST \\\n  -d '{\"agentName\":\"Example x402 API\",\"listingText\":\"A paid x402 API that helps builders check whether buyer agents understand the offer before paying.
