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.
25providers measured
15 (60.0%)declare their own
3 (12.0%)covered by others only
1 (4.0%)distribution only (sell through, not integrations)
6 (24.0%)undeclared
14declare compatibility (report only, not weighted)
Provisional. Provisional and unweighted: the Market layer is not part of the composite or agent readiness. Leader lists are read within a position, never as one ranking. A provider that declares nothing we can
read is shown as undeclared, with no number: we never infer integrations.
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.
Taxonomy how this market maps onto apis.io
Derived 2026-10-23 from the 25 providers in this market we could resolve in the
catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.

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
Report only, not weighted (Kin, 2026-10-13): `compatible` edges are shape votes (the provider re-serves the anchor's contract). They are shown here and as 'declares compatibility' on a provider, and are excluded from depth, position and the own/covered declaration until they hold across four weekly snapshots.
Pattern: fork. Shape gravity (counted by company, one edge per provider, the best
evidence kept): 8. 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.
