Sideko is an API tooling generation platform that turns an OpenAPI specification into a complete developer-tooling suite — SDKs in six languages (Python, TypeScript, Java, Go, C#, Rust), Model Context Protocol (MCP) servers for AI agents, on-brand documentation sites with an Automatic MCP surface, mock servers, and CLI tooling — without writing generation code. The platform's "Hybrid Codegen" pairs deterministic OpenAPI-driven generation with guided AI customization, and ships LLM coding-assistant rule files (Claude Code, Cursor, Gemini, GitHub Copilot) alongside each SDK so agents can extend the generated code without breaking regeneration. Customers include Prudential Financial and Magic Hour AI; Sideko's published Stripe SDK benchmark generated over one million lines of SDK code in under sixty seconds.
Sideko publishes 18 API contracts indexed on the APIs.io network, including API Projects API, API Versions API, Authentication API, and 15 more. Tagged areas include CLI, Documentation, Mock Servers, Platform, and SDK.
The Sideko catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Sideko’s developer surface includes authentication, documentation, signup flow, pricing, engineering blog, GitHub presence, changelog, and 12 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/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:
<a href="https://apis.io/providers/sideko/"><img src="https://apis.io/badge/sideko/card.svg" alt="Sideko on APIs.io — Kin Score by API Evangelist"></a>

Kin Score — facets with the most composite points still available (weight × headroom):
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Sideko is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.

Sideko can lift the SDK pointers (Python, TypeScript, Go, Rust, Java and C# GA, Ruby beta), a CLI, documentation and reference pointers, and a sandbox pointer through its mock servers. Each counts only when declared in apis.yml. Its docs MCP is one template across customers, so platform (0.25). Sideko’s own docs on the same platform are a JavaScript shell to a plain reader: 11 characters of text before rendering. That puts any docs-derived probe on a Sideko site at risk of a false negative. The CLAUDE.md files it writes into SDKs are coding-assistant context, not Agent Skills.

What Sideko ships that earns nothing (3)
LLM coding-assistant files (CLAUDE.md) — A CLAUDE.md inside an SDK repo is coding-assistant context, not an Agent Skill, and it is not declared on the provider’s surface.
SDK generation — SDK snippets are not request or response examples on the contract’s operations.
SDK generation — Generation does not add an idempotency key to the contract.
A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

on-brand documentation sites with an Automatic MCP surface, mock servers, and CLI tooling — without writing generation code.
The platform's "Hybrid Codegen" pairs deterministic OpenAPI-driven generation with guided AI customization, and ships LLM
coding-assistant rule files (Claude Code, Cursor, Gemini, GitHub Copilot) alongside each SDK so agents can extend the generated
code without breaking regeneration. Customers include Prudential Financial and Magic Hour AI; Sideko's published Stripe
SDK benchmark generated over one million lines of SDK code in under sixty seconds.
