API.market

API.market is a marketplace for discovering, testing, and monetizing APIs and AI models. It is best suited to developers and businesses that want a shared way to access multiple providers, and sellers who want to publish products without a listing fee. Its unified buyer and seller tools are appealing, but routing traffic through a proxy that logs full requests calls for care with sensitive data.

Overview

The marketplace advertises more than 590 APIs and AI models across areas including AI, image generation, fintech, security, travel, and developer tools. It also offers access to more than 3,670 API tools through one MCP connection. Buyers can try APIs in a Playground without setting up SDKs, or use auto-generated apps to interact with them. Most listings offer free trials, though availability depends on the individual API.

API.market proxies requests and handles authentication, billing, rate limiting, and analytics. Buyers get one API key, usage-based billing, and real-time metrics, which can simplify work across providers. The trade-off is that requests pass through a central service: API.market says it logs full request and response data, including headers and bodies, for billing, usage tracking, debugging, abuse prevention, and service improvement. Proxy request and response bodies are typically purged after 30 days, and in-house API media after 48 hours. Third-party API providers may see requests and apply their own retention policies. MagicAPI Inc says it does not sell, rent, or trade users’ personal information.

Key features

Seller onboarding starts with importing an OpenAPI specification. Sellers can set subscription, pay-per-use, or tiered pricing; API.market generates documentation, a test console, and an MCP endpoint for each product. A dashboard tracks uptime, subscriptions, and revenue. Autoscaling, key rotation, rate limits and quotas, usage metering, invoicing, global payouts, product versioning, and customer support tickets round out the seller toolkit. That breadth makes the marketplace more than a storefront, though sellers give the platform a share of each sale.

The MCP gateway provides connection instructions for Claude, ChatGPT, Codex, Cursor, VS Code, and Claude Code, with OAuth or API-key authentication. This is useful for teams working across those tools, while buyers whose priority is keeping request data away from intermediary services should consider the logging and provider exposure before integrating.

Pricing

The API seller listing plan costs free, with no listing fee or monthly platform fee and no cap on published products. Sellers keep 80% of each sale; the platform fee can be renegotiated above $2,500 MRR. The free entry point lowers the cost of testing a marketplace listing, but the 20% platform share is material as sales grow.

Enterprise AI model licensing starts at $599 a month, plus a one-time $299 deployment and integration fee. It includes unlimited usage during the launch period and self-hosted deployment in the customer’s cloud or data center. The license cannot be resold and is restricted to use within the purchasing organization, so it is aimed at internal enterprise deployment rather than resale or redistribution.

Platforms

API.market is offered as an API, a web service, and a self-hosted option. Enterprise model deployment can run in a customer’s cloud or data center and advertises a 99.9% uptime SLA. Support is advertised as 24/7, and form inquiries receive a response within 24 hours.

Who it's for

API buyers, developers, businesses, and startups can use the marketplace to explore and connect to multiple API and AI-model listings through a unified interface. Sellers get listing and monetization tools without a fixed platform fee. Enterprise buyers that need internal model deployment can request custom integrations and dedicated support. It is a weaker fit for organizations unwilling to route complete request and response data through API.market or expose third-party providers to their requests.

Pros and cons

• Pro: A catalog of 590+ APIs and AI models, plus 3,670+ tools through one MCP connection, gives buyers a broad place to discover integrations.
• Pro: The Playground, auto-generated apps, unified key, usage billing, and real-time metrics reduce setup and provider-by-provider administration.
• Pro: Sellers can publish unlimited products for free and get pricing, documentation, testing, metering, and payout tools in one service.
• Con: Full request and response logging, including headers and bodies, makes the service a consequential privacy choice for sensitive traffic.
• Con: Third-party providers may see routed requests and use their own retention policies, so data handling can vary by API.
• Con: Enterprise licenses prohibit resale and are limited to the purchasing organization, narrowing their use to internal deployments.

Alternatives

Verdict

API.market is a strong fit for sellers who want a no-fee listing path and buyers who value broad API and model discovery, unified access, and MCP connectivity. Its main advantage is bringing discovery, testing, billing, and seller operations into one marketplace. Look elsewhere if full request logging or third-party data exposure conflicts with your privacy requirements, or if you need enterprise model rights that permit resale.
