Tidelift
Tidelift provides open-source software supply-chain management for enterprises. Its platform combines package intelligence (maintenance, quality, end-of-life, and vulnerability signals) with catalogs of approved dependencies, policy and license standards enforcement, SBOM import/export, and "alignment" of projects against an organization's standards. Tidelift is distinctive for paying the open-source maintainers ("lifters") behind the packages enterprises rely on. The Tidelift External API (OpenAPI 3.0, Bearer API-key auth) exposes catalogs, violations, projects, groups, packages, releases, vulnerabilities, licenses, and reporting. Tidelift was acquired by Sonar in 2025; the API and developer surface remain active.
Tidelift publishes 15 API contracts indexed on the APIs.io network, including Alignments API, Attestations API, Authentication API, and 12 more. Tagged areas include Company, Open Source, Software Supply Chain, Dependency Management, and Application Security.
The Tidelift catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Tidelift’s developer surface includes documentation, API reference, getting-started guide, support, pricing, authentication, CLI, and 26 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Software Supply Chain (SBOM, Signing, Open Source Security) | standard | 44.1 | - | - |
| Cloud Security Attestation and Secure-by-Design | standard | 44.1 | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 1
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.
