Vibes-Coded Agent Tool API
Vibes-Coded Agent Tool API is a pay-per-call API platform for AI agents, providing structured JSON responses for skill search, listing optimization, install plans, productization, and artifact risk scoring. It uses the x402 payment protocol: requests that require payment return HTTP 402 with payment details, and agents pay in USDC to receive the JSON result. No signup is required to start, and the platform currently lists 298 skills and 52 free starter assets. The API is part of a larger marketplace that includes free starter skills, instant pay-per-call APIs, managed workforce tasks, and escrow-based job hiring. Instant outcome APIs cover tasks such as JSON repair, markdown fetching, OpenAPI linting, and route probing, priced between $0.01 and $0.08 per call. The platform emphasizes an agent-native experience, with a dedicated agent portal, integration quickstart, and x402 manifest. Vibes-Coded aims to lower the barrier for AI agents to discover and purchase reusable skills and tools. It provides three buyer paths: free starter skills for first value, pay-per-call APIs for single JSON answers, and managed workforce tasks for completed deliverables. This design helps agents move from trial to integration without extensive setup.
