HomeLight

HomeLight is a San Francisco–based real-estate technology company that matches home buyers and sellers with top-performing local real-estate agents and operates a stack of consumer-facing products that span the entire residential transaction: agent matching, Simple Sale cash-offer marketplace, Buy Before You Sell (BBYS) bridge financing, HomeLight Home Loans (NMLS #1529229), the HomeLight HELOC Card, and HomeLight Closing Services for title and escrow. The company ranks agents using historical performance data on home sales (price, speed, volume, geography, property type) and routes consumer leads to a curated network of agents, lenders, and cash-buyer investors. HomeLight exposes a private Partner API to lenders, brokerages, CRMs, and marketing partners (NerdWallet is its largest partner) for submitting leads (`/api/partner_lead/v2`), Simple Sale seller leads (`/leads/partner_simple_sale_lead`), and duplicate-lead checks (`/api/partner_dupe_lead_check`); credentials are issued on a per-partner basis via support@homelight.com. Beyond the Partner API, HomeLight has direct integrations with most major real-estate agent CRMs (Follow Up Boss, BoomTown, Sierra Interactive, Firepoint, Real Geeks, Brivity, Chime, LionDesk, KW Command). HomeLight has no public, self-service developer portal — the Partner API is gated by a commercial relationship, and there is no public OpenAPI spec, SDK, or open-source client published by the company.

HomeLight is listed with 1 API on the APIs.io network. Tagged areas include Real Estate, PropTech, Agent Matching, Cash Offers, and iBuyer.

HomeLight’s developer surface includes engineering blog, GitHub presence, YouTube channel, support, and 17 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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
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

13 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 13.2 — up to +17.4 composite points
Developer Ergonomics scores 16.7 — up to +16.7 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/homelight/apis.yml: open an issue on github.com/api-evangelist/homelight to ask a question or point us at an artifact you publish.

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
Consumer Lending Licensing (UK, US, Canada credit licence registers)	undeclared	-	-	1

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.
