API.market vs Datovu

API.market is a marketplace for discovering, testing, integrating, listing, and monetizing APIs and AI models. Its catalog advertises more than 590 APIs and AI models, along with more than 3,670 API tools accessible through one MCP connection. Buyers can try APIs in a Playground without setup or SDKs and use auto-generated apps to interact with them. The service describes unified access through one API key, usage-based billing, and real-time metrics. Sellers can import an OpenAPI specification, set subscription, pay-per-use, or tiered pricing, and generate product documentation, a test console, and an MCP endpoint. Their tools include pricing and subscription management, usage metering, rate limits, invoicing, versioning, and revenue monitoring. API.market proxies requests and handles authentication, billing, rate limiting, and analytics. Free seller listings have no listing or monthly platform fee; sellers keep 80% of sales, with a platform fee up to 20%, renegotiable above $2,500 MRR. Enterprise AI model licensing starts at $599 per month, plus a one-time $299 deployment and integration fee.

Datovu builds data APIs from datasets, letting users collect, index and monetize data without writing backend infrastructure. Its AI agent can plan research from natural-language instructions, search across sources and return structured data. Inputs include CSV, JSON and PDF files, pasted text, connected data feeds and web results, combined in a searchable index. The API builder generates REST endpoints with pagination, filtering and documentation. Publishers can add checkout, usage metering and payouts through Stripe Connect, and the marketplace lets people discover and subscribe to data APIs without an account. Datovu is available on the web and by API, with cloud deployment. The Free plan is free and includes 150 actions per month, one published API, one dataset, 100 documents and 1,000 API requests per month. Paid plans start at $29 a month. Operations stop at plan limits without overage charges, with alerts at 80%, 90% and 100% usage. Datovu says data is isolated per user and team, with zero-retention options.
