API.market

Overview

The marketplace brings more than 590 APIs and AI models together, spanning areas such as AI, image generation, fintech, security, travel, and developer tools. It also advertises more than 3,670 API tools through one MCP connection. Buyers can try APIs in a browser-based Playground without setting up SDKs, or use auto-generated apps to interact with them.

API.market proxies requests and manages authentication, billing, rate limits, and analytics through a unified interface. Buyers use one API key, usage-based billing, and real-time metrics. That can simplify access across listings, though it also puts a central service between the buyer and API provider.

Key features

For sellers, importing an OpenAPI specification can generate product documentation, a test console, and an MCP endpoint. Sellers can set subscription, pay-per-use, or tiered pricing, then manage products and monitor uptime, subscriptions, and revenue. The seller toolkit also includes autoscaling, key rotation, quotas, usage metering, invoicing, global payouts, versioning, and support tickets—substantial operational coverage for a marketplace listing.

The MCP gateway offers connection instructions for Claude, ChatGPT, Codex, Cursor, VS Code, and Claude Code, with OAuth or API-key authentication. This makes the catalog relevant to developers working through those tools, rather than only conventional API clients.

Privacy deserves particular attention. API.market says it logs full request and response data, including headers and bodies, for billing, debugging, abuse prevention, and service improvement. Proxy request and response bodies are typically purged after 30 days, while in-house API media is deleted 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, but that assurance does not remove the implications of request logging.

Pricing

API.market is freemium, with a free plan and a free-trial option. Most APIs offer trials, but availability depends on each listing, so access is not uniform across the catalog.

• API seller listing: 0.00 USD per free. There is no listing fee or monthly platform fee, and sellers can publish as many products as they like. Sellers keep 80% of each sale; the platform fee is up to 20%, with renegotiation possible above $2,500 MRR. This is a low-commitment way to reach buyers, though the revenue share matters as sales grow.
• Enterprise AI model licensing: 599.00 USD per month, starting at $599 per month, plus a one-time $299 deployment and integration fee. It includes unlimited usage during the launch period and self-hosting in the customer’s cloud or data center. The license prohibits resale and limits use to the purchasing organization, making it unsuitable for anyone intending to redistribute the model.

Enterprise buyers can request custom integrations and dedicated support. The enterprise offer advertises a 99.9% uptime SLA; the model-license terms still constrain how the licensed models can be used.

Platforms

API.market supports API, web, and self-hosted use. Its enterprise deployment option lets customers run AI models in their own cloud or data center, while the MCP gateway connects the marketplace to several coding and AI assistants.

Who it's for

API buyers who want to compare and try offerings through one interface, developers using MCP-compatible tools, and startups or businesses sourcing APIs are the natural audience. API sellers may value the free listing and built-in billing and operations tools. Organizations with deployment requirements can consider the enterprise offer, provided they need internal use rather than resale.

Pros and cons

• Pro: A catalog of 590+ APIs and AI models, with Playground testing and one-key access, reduces setup friction for buyers exploring multiple services.
• Pro: Sellers can publish without listing or monthly platform fees and get pricing, billing, analytics, and product-management tools in one place.
• Pro: Self-hosted enterprise deployment and a stated 99.9% uptime SLA suit organizations that need deployment within their own environment.
• Con: Full request and response logging can expose sensitive payloads to retention and review; third-party providers may have separate policies.
• Con: The enterprise license bars resale and confines use to the purchasing organization, limiting commercial redistribution.
• Con: Seller fees can reach 20% of sales, and trial availability varies by API listing.

Alternatives

Choose api0.app if a small, clearly capped free marketplace is enough: its free plan allows two live endpoints and 10,000 requests per month. RapidAPI is another freemium API marketplace, with provider-set pricing and quotas that vary by plan. For pay-as-you-go access with the first 100K calls per month free forever and no minimums or seats, consider APIDistributed.

FabriXAPI is worth comparing when its Starter plan’s stated caps—3 public plans, 50 unlisted plans, 100K calls per API plan, 100K API volume per month, and 100 monthly active subscriptions—fit the need. Comviva API Marketplace is a paid alternative. APILayer Marketplace offers a free plan capped at 100 requests monthly, or a $19.99-per-month Starter plan with 6,000 requests.

For API development and collaboration tools rather than a marketplace-first choice, Postman has a free plan with an API client, core tools, specs, mock servers, and native Git. SAMi API Storefront is another paid marketplace option. See the full API Marketplace Software category for more choices.

Verdict

API.market is a strong fit for buyers who want broad API discovery and unified access, and for sellers who want marketplace reach without fixed listing fees. Its main reasons to look elsewhere are the full-payload logging and the limits third-party retention policies can impose; enterprise buyers must also accept an internal-use-only license. It is most persuasive when centralized access and seller tooling outweigh those data and licensing constraints.
