Search API (Elasticsearch / OpenSearch shape)
Frontier, two related de facto shapes (elasticsearch and its opensearch fork), converging by imitation. The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- Providers' own Elasticsearch/OpenSearch compatibility pages (fetched, saved under evidence/compatibility/) machine-readable
- Providers' own contracts naming the Elasticsearch/OpenSearch API machine-readable
- Structural detection: _bulk/_cat/_mapping/_doc paths and OpenSearch /_plugins/ in providers' contracts (ours, marked) machine-readable
- Conformance test running the Elasticsearch/OpenSearch client test suites against each endpoint not machine-readable: no register exists; not built
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.

Shape adoption report only — not weighted
Pattern: fork. Shape gravity (counted by company, one edge per provider, the best evidence kept): 7. Convergence in the cohort: 7 of 11 (63.6%) — cohort members (minus the anchor's family, mediators and rival shapes) with at least one compatible edge to the shape, read from evidence.
