API.market

API.market (Noveum) is an API marketplace launched in April 2024 where developers discover, subscribe to and call third-party APIs and AI models with one account, one x-api-market-key and unified billing, and where sellers import an OpenAPI source, set pricing plans and get paid. The platform itself exposes a hosted MCP gateway at https://api.market/api/mcp/gateway (Streamable HTTP, OAuth 2.1 with dynamic client registration, or API key) with five tools (search_apis, get_api_tools, call_api, check_usage, manage_subscription), a Subscription Management REST API and a read-only Usage API. Individual APIs sold on the marketplace belong to their own providers and are not listed here.

API.market is listed with 15 APIs on the APIs.io network, including API.market API, Bridgeml API, Images API, and 12 more. Tagged areas include API Marketplace, MCP, AI Agents, API Monetization, and Subscription.

The API.market catalog on APIs.io includes 1 Spectral governance ruleset.

API.market’s developer surface includes pricing, changelog, authentication, documentation, getting-started guide, engineering blog, support, and 30 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
