SCORECARD

ExistenceGOODReal APIs exist across product lines, led by the ingresso B2B distribution API feeding resellers like Expedia and Klook.
AccessPOOREven the docs are gated: you email the commercial team for a URL and password; every integration starts with sales.
CoveragePOORNine product lines each carry their own API surface; there is no unified accesso developer platform.
AuthPOORIdentity models differ across the acquired products and nothing about auth is publicly documented.
Docs & DXPOORThe Knowledge Base with API references requires customer login; partners cannot evaluate limits or webhooks pre-contract.
StabilityMIXEDOverlapping acquired products and a migration push toward Horizon leave roadmap and API lineage unclear.
Supergood: accesso has an API, but using it means gates, contracts, or workarounds. Ours doesn't: stable endpoints, normalized JSON, managed auth.
