Hang

Hang is a customer loyalty and engagement platform (originally a Paradigm-backed Web3 brand-loyalty company, now positioned as an AI-driven "autonomous marketing system") used by restaurant, beauty, apparel, and e-commerce brands to build and run tier-based membership and rewards programs. Its Partner API powers program memberships, points and activities, quests, challenges, puzzles, loot/mystery boxes, rewards and redemptions, balance/gift cards, tokenized rewards, program tiers and segments, plus point-of-sale integrations with Toast and Square and real-time webhooks. Brands can embed a white-labeled rewards portal or drive the whole loyalty experience programmatically through the REST API.

Hang publishes 29 API contracts indexed on the APIs.io network, including Activities API, Loot Box Reward Choices API, Loot box reward probabilities API, and 26 more. Tagged areas include Company, Consumer, Loyalty, Rewards, and Membership.

The Hang catalog on APIs.io includes 1 event-driven AsyncAPI specification.

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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

Markets this provider is in provisional

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Restaurants and POS	builds-on	34.5 (thin)	-	-

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.
