# Swiftly

> Swiftly (Swiftly Systems, Inc.) is a Seattle-based retail technology company selling an AI
> platform for grocery, convenience and wholesale retail. It builds white-labeled shopper
> mobile apps and websites for regional and independent retailers and runs a multi-retailer
> closed-loop retail media network. Swiftly publishes no public developer program: there is
> no developer portal, no API reference and no SDK. The shopper-facing GraphQL API that
> backs its retailer apps is nonetheless anonymously introspectable.

Generated by the API Evangelist enrichment pipeline on 2026-08-05. Swiftly does not publish
an llms.txt of its own (https://swiftly.com/llms.txt returns 404). Everything below was
either fetched from Swiftly's public surface or derived from the introspected schema — no
part of it is a Swiftly claim about its API.

## API

- [Swiftly Shopper GraphQL API](https://prod.swiftlyapi.net/graphql): 45 queries, 11
  mutations, 308 types. Covers offers and coupons, product catalog and barcode lookup,
  store and chain directories, digital circulars, loyalty programs, rewards and challenges,
  shopper accounts and age verification, and retail-media ad placements. Undocumented;
  introspection is enabled for anonymous callers.
- [Health endpoint](https://prod.swiftlyapi.net/health): returns build version and commit.

## Specs and artifacts

- [GraphQL SDL](graphql/swiftly-shopper.graphql): the full schema rendered as SDL.
- [Introspection document](graphql/swiftly-shopper-introspection.json): the verbatim
  introspection response.
- [Data model](data-model/swiftly-data-model.yml): entity graph and relationships.
- [Conventions](conventions/swiftly-conventions.yml): pagination, tracing, versioning,
  error envelope, rate-limit signalling.
- [Authentication](authentication/swiftly-authentication.yml): tenant key header plus
  shopper bearer token.
- [Error catalog](errors/swiftly-problem-types.yml): the GraphQL errors[] envelope and the
  failure classes observed live.
- [Lifecycle](lifecycle/swiftly-lifecycle.yml): in-schema versioning and 13 @deprecated
  fields.
- [Conformance](conformance/swiftly-conformance.yml): which standards the API meets.
- [MCP proposal](mcp/swiftly-mcp.yml): a derived candidate tool surface. Swiftly operates
  no MCP server.
- [Agent skills](skills/_index.yml): operating instructions grounded in real schema fields.
- [Domain security](security/swiftly-domain-security.yml)
- [Trust center](security/swiftly-trust-center.yml)
- [Well-known probe log](well-known/swiftly-well-known.yml)
