Replica
Replica is a San Francisco-based data platform for the built environment, spun out of Alphabet's Sidewalk Labs in 2019, that operates a nationwide activity-based travel model. Its analytical engine combines public data (US Census/ACS, GTFS transit feeds, OpenStreetMap road networks, land-use records, state traffic counts) with licensed private data (de-identified aggregate mobile location, credit transaction and driving-behavior data) to synthesize a privacy-preserving simulated population and a complete trip table for the United States. Products include Places (seasonal, high-fidelity activity-based travel model), Trends (weekly near-real-time mobility and land-use data), Safety Hub, Safe Streets Planner, and a suite of workflow applications used by state DOTs, MPOs, transit agencies, cities and counties. Data is consumed through the Replica Studio web platform, CSV export and direct database access; Replica publishes documented dataset schemas at documentation.replicahq.com but no public developer REST API, SDK or developer portal.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Replica the way a machine reads it — 20 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Replica scores 26.0/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Put this on your own site. The badge is drawn live from Replica's current Kin Score — paste it once and it updates itself every time the score is recomputed. It follows your visitor's light or dark setting, and it links back here so anyone who sees it can read the full breakdown.

How we profile Replica
Each block below is one kind of artifact we hold for Replica. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
JSON Schema 19
Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Replica, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
