This page carries no rating. Capabilities are not rated. A capability is a description of what a business does, not a thing a company publishes, so a Kin Score would have nothing to measure.
The edge table is a Pro feature. This page shows which providers and tags reach Blockchain & Digital Assets. The underlying tag → capability edges — each with the quoted fragment of the provider's own OpenAPI that evidences it, a calibrated confidence score, and the contract-provenance gate it passed — are available through the API, along with company-level capability maps. Only edges at confidence ≥ 0.7 with evidence found verbatim in the source contract are published at all.
