Fusio

Fusio is Apache-2.0, self-hosted API management from apioo (Christoph Kappestein, Germany). An operator installs it and builds APIs inside it: an operation binds an HTTP method and path to an action (SQL, HTTP, MongoDB, Elasticsearch, an LLM agent, or code running in a JavaScript, Python, Java or PHP worker) and a TypeSchema-defined request and response shape. Every instance then generates its own machine-readable contract live - OpenAPI 3.0.3, OpenRPC 1.3.0 and TypeAPI - and serves an RFC 9727 api-catalog, RFC 8414 and RFC 9728 OAuth metadata, OpenID Connect discovery and an RFC 9116 security.txt out of the box. It ships its own OAuth2 authorization server, an Angular developer portal, a rate-limiting and monetization layer, a webhook and trigger system, and an MCP server that turns every published operation into an agent tool. There is no vendor-hosted tier and no pricing: the software is the product.

Fusio publishes 43 APIs on the APIs.io network, including Account API, Action API, Agent API, and 40 more. Tagged areas include API Management, Open Source, REST API, API Gateway, and Developer Portal.

The Fusio catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Fusio’s developer surface includes CLI, sandbox, changelog, API reference, authentication, documentation, getting-started guide, and 43 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.
Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against 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 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/fusio: open an issue to ask a question, or submit a pull request to add artifacts.

Work with this as data

Every provider here is available over the APIs.io API and to AI agents over MCP.

MCP server

One button, every client — Claude, Cursor, VS Code and the rest.

Tools for providers

9 MCP tools reach this
  • find_providersBrowse and filter every provider in the catalog.
  • get_provider_artifactsEvery artifact this provider publishes, grouped by type.
  • get_provider_operationsEvery operation across all of their OpenAPIs — one call instead of parsing every spec.
  • get_provider_toolsEvery MCP tool they ship, with the operation each wraps.
  • get_provider_evidenceHow each part of their score was established. Free — the basis for a claim should not sit behind it.
