Derived 2026-10-21 from the 35 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.

share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py

Top workflows by market votes

Workflows (Arazzo) and their phrasing are generated by API Evangelist, ranked by market votes (integration edges in the graph, weighted by channel).

In-market workflows only: a step on the market provider's side maps to this market's business capabilities (), and the partner is not a generic export/notify app. Other workflows are counted as bridges (including any whose steps do not resolve to a capability yet). Methodology. In-market: 71; bridges: 0.
