Built for the real quote-only drop-off where buyers can see a 402 quote but never produce X-PAYMENT. This deterministic endpoint does not call an upstream model, never asks for private keys, and never sends a payment itself. Pay up to $0.012 per request with x402 USDC on Base. Public paid calls are limited to 700000 input characters and 4096 output tokens.","url":"https://gpt55.558686.xyz/v1/tools/x402-buyer-client-adapter-pack","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"url":{"type":"string","maxLength":2048,"minLength":1},"method":{"enum":["GET","POST","PUT","PATCH","DELETE"],"type":"string"},"paid_route":{"type":"string","maxLength":2048,"minLength":1},"buyer_runtime":{"type":"string","maxLength":80},"mcp_tool_name":{"type":"string","maxLength":160},"expected_asset":{"type":"string","maxLength":80},"wallet_env_var":{"type":"string","maxLength":80},"expected_pay_to":{"type":"string","maxLength":120},"package_manager":{"type":"string","maxLength":40},"expected_network":{"type":"string","maxLength":80},"daily_budget_usdc":{"type":"number","maximum":10000,"minimum":0.0001},"max_usdc_per_call":{"type":"number","maximum":100,"minimum":0.0001},"request_body_example":{"type":["object","string","null"]},"require_receipt_evidence":{"type":"boolean"}}},"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.012","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.012/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.012","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.012","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_KX8a3m_THqmS5feHa_ll0","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.012","costPer":"request","priority":0,"asset":null,"unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Generates a complete buyer client adapter pack (Node.js fetch client, Python/httpx outline, MCP tool wrapper, retry checklist, environment contract, receipt policy, and failure-stop conditions) for integrating with a paid x402 route.","exampleAgentPrompt":"Generate me a full x402 buyer client adapter pack for a POST endpoint at https://api.example.com/v1/analyze, with a max spend of $0.05 per call and a $2.00 daily budget, expecting payment on Base in USDC to address 0xAbC123, using Node.js as my runtime, npm as my package manager, and requiring receipt evidence — include the MCP tool wrapper named 'analyze-tool'.","exampleUseCases":null,"resultDescription":"A structured adapter pack including: an official-style Node.js fetch client, a Python/httpx outline, an MCP tool wrapper, a same-request retry checklist, an environment variable contract, a receipt capture policy, and explicit failure-stop conditions — all tailored to the specified x402 paid route parameters.","failureModes":["Input URL or paid_route missing or exceeds 2048 characters — validation error returned","max_usdc_per_call exceeds $100 maximum — rejected with validation error","buyer_runtime or package_manager value not recognized — may produce generic scaffolding","expected_pay_to address malformed — adapter pack may contain placeholder values","Input character limit of 700,000 exceeded — request rejected","Daily budget below minimum of $0.0001 — rejected with validation error"],"whenToPreferThis":"Choose this endpoint when you need to quickly scaffold a complete, opinionated buyer-side integration for an x402-protected route and want ready-to-use Node.js and Python code, an MCP tool wrapper, and operational policies (receipt capture, retry, failure-stop) all in one deterministic pass — rather than manually assembling client code and operational guidance from scratch.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-13T12:50:03.878Z","isFirstParty":false}
