API.market

API.market combines API discovery and access with tools for publishing and selling APIs and AI models. It is a strong fit for developers who want a shared route to multiple services and sellers who need marketplace billing and product controls. Its central proxy and seller toolkit are useful, but buyers routing sensitive data should take its logging practices seriously.

Overview

The marketplace advertises more than 590 APIs and AI models, from AI and image generation to fintech, security, travel, and developer tools. It also offers access to more than 3,670 API tools through one MCP connection. Buyers can explore services in an API Playground without SDK setup, or use auto-generated apps; one API key, usage-based billing, and real-time metrics can make trying multiple listings less cumbersome.

API.market proxies requests and handles authentication, billing, rate limits, and analytics. That shared layer simplifies access, but it also means requests pass through the marketplace. API.market says it logs complete request and response data, including headers and bodies, for billing, usage tracking, debugging, abuse prevention, and service improvement. Bodies are typically purged after 30 days, while in-house API media is deleted after 48 hours. Third-party providers may see requests to their APIs and apply their own retention policies. MagicAPI Inc says it does not sell, rent, or trade users’ personal information.

Key features

Buyers can test APIs without first configuring an SDK, and MCP connection instructions cover Claude, ChatGPT, Codex, Cursor, VS Code, and Claude Code, with OAuth or API-key authentication. Most API listings offer free trials, though the individual listing determines whether one is available. These tools help with evaluation, but they do not remove the need to check each provider’s terms and data practices.

For sellers, importing an OpenAPI YAML specification can produce a listing within minutes. Sellers can choose subscription, pay-per-use, or tiered pricing, with documentation, a test console, and an MCP endpoint generated for each product. A dashboard covers uptime, subscriptions, and revenue; the broader toolkit includes autoscaling, key rotation, rate limits and quotas, metering, invoicing, global payouts, versioning, and customer support tickets. This is a substantial set of operational controls for a marketplace listing, though sellers give up a share of each sale.

Enterprise buyers can deploy AI models in their own cloud or data center, with a stated 99.9% uptime SLA and options for custom integrations and dedicated support. The license terms matter: models cannot be resold and may only be used within the purchasing organization.

Pricing

The API seller listing plan costs free, with no listing fee or monthly platform fee and no stated product-count cap. Sellers keep 80% of each sale; the platform fee is up to 20%, with renegotiation possible above $2,500 MRR. This is a low-friction way to publish, but the revenue 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-hosting in the buyer’s cloud or data center. The organizational-use restriction makes this suitable for internal deployment, not for a business that intends to resell model access. No seat or launch-period duration is stated.

API.market is freemium, and a free plan and free trial are offered. Individual API trials depend on the listing. The enterprise starting price is the clearest buyer-side price point; seller fees and enterprise license terms are the more consequential costs for their respective audiences.

Platforms

API.market supports API, web, and self-hosted use. Enterprise deployment can run in a customer’s cloud or data center. The MCP gateway’s connection options make it relevant to users of several coding and conversational tools, while the core marketplace is not tied to a single desktop operating system.

Who it's for

API buyers, developers, startups, and businesses can use the marketplace to discover and evaluate APIs through a shared access layer. API sellers get publishing, billing, and monitoring tools without a listing or monthly platform fee. Enterprise buyers should consider it when self-hosting and internal model use fit their needs; organizations requiring resale rights should look elsewhere.

Pros and cons

Pros: A catalog of more than 590 APIs and AI models, plus 3,670+ tools through one MCP connection, gives buyers a broad starting point for discovery.

Pros: Playground testing, auto-generated apps, and unified access can reduce setup work when evaluating multiple APIs.

Pros: Sellers can publish without listing or monthly platform fees and receive a broad toolkit for pricing, metering, payouts, and monitoring.

Cons: Full request and response logging, including headers and bodies, is a significant consideration for sensitive traffic, even with stated purge periods.

Cons: Third-party providers may see routed requests and follow their own retention policies, so the marketplace cannot be treated as the only data-handling party.

Cons: The enterprise license starts at $599 a month, adds a one-time $299 fee, and bars resale while limiting use to the buyer’s organization.

Cons: Sellers retain 80% of sales under the standard fee, with renegotiation only available above $2,500 MRR.

Alternatives

Choose API Marketplace Software to compare the broader category. Postman is a better fit for teams focused on API development workflows, with a free plan covering an API client, specs, mock servers, native Git, and a Collection Runner. Kong Gateway suits buyers seeking gateway controls, including a 30-day trial with no Gateway limits and 30 days of analytics retention.

Gravitee API Gateway is worth considering for teams that want an Apache 2.0 community edition or a paid Planet plan at $2,500 a month. Zuplo may suit a smaller deployment: its free plan allows up to 100K requests per month, two account members, and five environments. Moesif is another option for API analytics, with a free plan applied after its 14-day trial.

WSO2 API Designer is the alternative to consider when API design is the priority; its 30-day trial includes five managed interfaces and 10M gateway events. Datovu has a free plan capped at 150 actions per month, one published API, and 1K API requests per month, making it a more constrained starting point. FabriXAPI is a fit for sellers who want a free starter plan with up to 100K API calls per plan and 100 monthly active subscriptions.

Verdict

API.market is a compelling choice for sellers who want to publish and monetize APIs with built-in billing and operational controls, and for buyers who value a shared route to a large API and AI catalog. Its main reason to choose is the combination of discovery, testing, MCP access, and seller infrastructure in one marketplace. Look elsewhere if full request logging or provider visibility is unacceptable for your data, or if enterprise model access must permit resale.
