Infrastructure

The provenance-tracked spec feed

The same verified store that renders this site and answers /ask, exposed as a read-only REST API and a remote MCP server. Built for AI assistants, shopping agents, and answer engines that need citation-clean structured vehicle data instead of hallucinating it.

The contract

What every response guarantees

Every value carries its manufacturer source URLs. A field without provenance is served as an explicit null — never bare, never estimated.
Nulls are first-class and say why: not-published when the manufacturer omits the figure, pending when it is published but not yet sourced here. Agents can distinguish the two.
Source disagreements are served verbatim, both positions, never arbitrated.
No LLM anywhere in the serving path — deterministic reads over the verified store. Machines get the same honest nulls humans do.

Coverage

What the feed serves

13 luxury 3-row SUVs · 214 verified field values · 60 cited sources · 15 spec fields and 4 third-row safety fields per model, plus derived persona scores with their rubric. Verification status is served per domain: dimensional specs carry per-source verification and availability; safety hardware carries a three-state status with stale-source flags.

Quickstart

REST API

Versioned under /v1, GET only, CORS-open, no key required. Machine-readable errors list valid slugs and fields. Full schema: openapi.json.

# Model directory
curl https://thirdrowreality-api.sntricity.workers.dev/v1/models

# One field, full provenance
curl https://thirdrowreality-api.sntricity.workers.dev/v1/models/escalade/fields/row3HeadroomIn

# Aligned comparison
curl "https://thirdrowreality-api.sntricity.workers.dev/v1/compare?models=escalade,navigator&fields=towingMaxLbs,latchLowerAnchorsRow3"

MCP server

Remote MCP over streamable HTTP at https://thirdrowreality-api.sntricity.workers.dev/mcp — six deterministic tools (search, specs, single field, compare, provenance, capabilities). Add it to an MCP client:

{
  "mcpServers": {
    "thirdrowreality": {
      "type": "http",
      "url": "https://thirdrowreality-api.sntricity.workers.dev/mcp"
    }
  }
}
