Transat A.T. Inc. (TSX: TRZ) is a Montreal-headquartered, vertically integrated Canadian leisure travel group. It operates Air Transat (IATA carrier code TS), a transatlantic and sun-destination leisure airline, alongside tour-operating brands (Transat / Transat Tours Canada Inc.) and one of Canada's largest retail travel agency networks (Transat Travel, Voyages Transat, Marlin Travel, Club Voyages). It sits on the supply side of the distribution chain: it owns the seat and package inventory, sells it direct through transat.com and airtransat.com, through its own retail agencies, through GDS/CRS EDIFACT channels governed by IATA Resolution 850m and BSP settlement, and — since its published NDC programme — through an Accelya Farelogix NDC gateway and a named set of NDC aggregators. Its API posture is partner-gated but not opaque: Air Transat publishes a public NDC connectivity page and a publicly downloadable 46-page "Air Transat API specifications" document, but that document is a proprietary Radixx ConnectPoint SOAP contract (v2.2.4, May 2023), not an IATA NDC schema. There is no self-serve developer portal, no machine-readable OpenAPI or WSDL, no published base URL, no sandbox, no bulk export operation, and no IATA NDC certification level is claimed. Credentials (a Transat-assigned IATA number, agency login and password) are issued only under a commercial agreement, and the site terms plus the CRS Booking and Ticketing Procedures Policy expressly prohibit scraping and prohibit redistributing Air Transat content to any third-party agent, GDS or metasearch engine without prior written consent.
Transat is listed with 1 API on the APIs.io network. Tagged areas include Travel, Canada, Aviation, Airlines, and Distribution.
Transat’s developer surface includes authentication, changelog, documentation, support, legal docs, engineering blog, and 19 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
11 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

notes: Contract discovery re-run against every Transat, Air Transat, api.transat.com and apis.airtransat.com host. No OpenAPI,
Swagger, WSDL, GraphQL, AsyncAPI, MCP server, /.well-known/ document or /llms.txt exists. The published 46-page Radixx
ConnectPoint specification PDF was fetched and parsed, and the artifacts below are grounded in it. No sandbox, status
page, trust centre, vulnerability-disclosure programme, SDK, CLI, Postman collection, webhook surface or idempotency contract
exists, so those artifacts and their pointers are deliberately absent rather than fabricated.

name: Air Transat NDC Direct Connect API (Radixx ConnectPoint)
description: 'The direct-connect flight shopping, booking, payment and servicing API that Air Transat publishes to OTA and
technology partners under its NDC programme. The only technical contract Transat publishes for it is the "Air Transat
API specifications" PDF — the Radixx ConnectPoint API, Flight Booking Detailed View, version 2.2.4, updated May 2023 —
a SOAP 1.1 / .NET WCF service using Radixx.ConnectPoint data contract namespaces and the tempuri.org service namespace.
The document names the following operations across the shopping, offer, order, payment and notification stages: RetrieveFastFareSearch
and RetrieveFareQuote / RetrieveFareQuoteShop (shopping and pricing, sourced either from the Radixx local system or the
Sabre shopping cache), RetrieveSecurityToken (session and authorization), LoginTravelAgent and RetrieveAgencyCommission
(agency identity and commissioning), SummaryPNR, CreatePNR (CommitSummary) and CreatePNR (SaveReservation) and RetrievePNR
(order creation and retrieval, including codeshare, interline and AMCI examples), ConvertCurrencies and ProcessPNRPayment
(payment), and Notification. Authentication is a LogonID / Password exchange that returns a SecurityGUID, scoped to AccessibleCarrierCode
"TS". No base URL, WSDL, sandbox or OpenAPI is published; Transat assigns each partner a pre-configured travel agency,
IATA number and credentials under a commercial agreement.'
