ingest0r
ingest0r operates the Cook County (Chicago) property records API at api.ingest0r.com — a pay-per-call, agent-native REST API over Cook County, Illinois public records (~1.9M parcels, refreshed nightly) that resolves a street address to its parcel PIN, then returns parcel details, recorded sales and deed history, building permits linked to the PIN, property-tax assessment history and comparable-sales valuation as one joined answer. There is no signup and no API key: address search and a fixed sample are always free, the first 25 PIN-route calls per client per day return real data free, and past that the routes answer HTTP 402 and are settled per call in USDC on Base or Solana through the x402 protocol ($0.01, $0.03 and $0.10). The provider publishes an OpenAPI 3.1, an A2A agent card, a live streamable-HTTP MCP server with five tools, llms.txt, an x402 resource list, a machine-readable price card and changelog, and a security.txt — all on api.ingest0r.com. The operator identifies itself only as "independent" (the agent card's provider.organization) with a personal contact address; the apex ingest0r.com has no DNS A record, so the API host is the website.
ingest0r publishes 5 API contracts indexed on the APIs.io network, including Comps API, Dossier API, Parcel API, and 2 more. Tagged areas include Company, Real Estate, Property Records, Property Data, and Public Records.
ingest0r’s developer surface includes documentation, pricing, changelog, authentication, sandbox, and 25 more developer resources.
Kin Score
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 |
|---|---|---|---|---|
| Government Cloud (FedRAMP, GovRAMP, G-Cloud) | undeclared | - | 1 | - |
| x402 Micropayments & Agentic Pay-per-Call | undeclared | - | 1 | - |
| Open Data Portals (CKAN / DCAT) | 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.
