A resource tag, not a market

No company describes its business as “Market Participants”. It names something an API does — and 4 providers reach it through a specification or operation tag. The APIs below are the answer to this tag; the companies are not.

Companies reaching this through an API (4)

These companies publish an API, specification or operation carrying “Market Participants” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.
