WestJet Airlines Ltd. is Canada's second-largest air carrier, headquartered in Calgary, Alberta, operating scheduled passenger service to more than 100 destinations across Canada, the United States, Mexico, Central America, the Caribbean, Europe and Asia, alongside WestJet Encore, WestJet Vacations, WestJet Cargo and the Sunwing Vacations Group. In the distribution chain WestJet sits upstream of the agency channel: its inventory reaches travel sellers today through EDIFACT in the Amadeus, Sabre and Travelport GDSs, and it is standing up an IATA NDC surface (schema 17.2 and 21.3/24.1) built and hosted on Accelya's FLX/Farelogix platform, with a stated Q4 2026 rollout. Its API posture is honest but closed: there is no public developer portal, no self-serve signup, no OpenAPI or WSDL and no consumer API. The WestJet Direct Connect API is documented only as a public capability matrix at westjetndc.com, and access requires an IATA or ARC accreditation number (TIDS is explicitly not supported), a business-type and sales-volume qualification form, and WestJet approval. Agency booking through WestJet Agent Direct likewise requires an IATA/TIDS/ARC number and a five-to-ten business day review. There is no bulk export for agency or booking data; guest data comes out only via a verbally authenticated PIPEDA-style "Guest information report" request.
WestJet is listed with 1 API on the APIs.io network. Tagged areas include Travel, Canada, Aviation, Airlines, and Distribution.
The WestJet catalog on APIs.io includes 1 event-driven AsyncAPI specification.
WestJet’s developer surface includes getting-started guide, changelog, engineering blog, developer portal, documentation, signup flow, support, and 25 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):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Machine-Readable Auth+10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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.

description: WestJet's IATA New Distribution Capability (NDC) direct-connect interface for travel sellers, offered in NDC
schema versions 17.2 and 21.3/24.1 and delivered on Accelya's FLX/Farelogix platform. Published capability tables cover
shopping (fare brands, fare types, complex itineraries, promo codes), ancillaries (EMD-A for bags and pre-reserved seats,
seat maps), order creation (book-and-hold, book-and-instant-ticket), payment and ticketing (credit/debit, BSP and ARC
cash, UATP, multiple forms of payment), settlement via BSP and ARC, change notifications (OCN), and servicing (CAT 33
voluntary refunds, True Reshop, waiver codes, split/divide PNR, SSR and OSI updates). No OpenAPI, WSDL, XSD or base URL
is published; enrolment is by application and requires an IATA or ARC accreditation number. WestJet states a Q4 2026 rollout,
with a $20-$22 USD Distribution Cost Recovery surcharge applying to non-NDC (EDIFACT) bookings on the lowest class per
cabin in NDC-enabled points of sale.
