API.market review
A broad marketplace for API discovery, publishing, monetization, and AI-agent access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
API.market is a web-based marketplace for discovering, testing, subscribing to, and integrating APIs and AI models. It serves both API providers and developers or businesses that need a marketplace for public or private API products. Providers can import OpenAPI specifications, publish products, configure pricing, and offer access through hosted documentation, an interactive test console, API keys, and gateway proxying. The platform also supports an automatically generated MCP endpoint for published APIs, making it relevant to teams working with AI-agent access.
The pricing model is freemium, with a Seller listing plan priced at $0 USD per month. That plan includes no listing fee, no monthly platform fee, and unlimited product publishing. API product prices are configured by individual providers, with subscription, pay-per-use, and tiered pricing supported. API.market retains up to 20% of sales, so the free listing model should be evaluated alongside transaction economics. This structure fits providers that want to publish multiple products without a recurring platform charge, while teams seeking a fixed paid plan may prefer a different commercial model.
Its feature coverage extends beyond catalog discovery: gateway proxying includes authentication, quotas, and rate limits; built-in billing covers invoicing and payouts; and analytics track usage, latency, and requests. Versioning, hosted documentation, and the interactive test console support ongoing API operations. Integrations include Claude Code, Cursor, VS Code, Windsurf, and ChatGPT. API.market is a strong fit for operators needing discovery, publishing, mixed monetization, billing, and AI-oriented access in one cloud platform. It is less suitable for organizations that require a fixed platform subscription, a different deployment model, or pricing control without a sales share.
