How access works

Request, scope, delivery.

There is no sign-up and no public key. A person reads your request, writes a scope, and sets up the delivery once you agree to it.

The four steps

  1. You send the request. Datasets, states or areas, delivery and what the data is for.
  2. We reply by email. Questions, plus a written scope: datasets, fields, geography, refresh schedule, delivery format, use terms and fee. Some counties are held back; the scope says so if your area includes one.
  3. You agree to the scope. Nothing is set up and nothing is billed before that.
  4. We set up your delivery. An API key, a file drop, or an agent endpoint, scoped to what was agreed, with a first sample for you to check.

What the written scope covers

  • Datasets and fields
  • States, and counties for the county index
  • Refresh schedule: one time, monthly, weekly or daily
  • Delivery: API, bulk files or agent endpoint, and where files land
  • Use terms: internal use, inside your product, or as input to your agent; whether model training on the rows or redistribution is allowed is written into the scope
  • Fee and how usage is counted

Three ways to receive it

API

JSON over HTTPS with a bearer key. Filter by state, county, API number or update date; page with a cursor. Fits applications that look up a well or permit at a time.

Available on request.

Bulk files

Parquet, CSV or JSONL per state with a manifest of row counts and checksums. Full drop first, then changed rows on your schedule. Fits a warehouse load.

Available on request.

Agent endpoint

An MCP server your agent connects to with its own key. A coverage tool tells the agent what we hold before it asks for rows. Use is metered per request.

Available on request.

Envelope, filters, no-data answers and the config block

Who supplies it

Our Landmen LLC, an independent land company in Cheyenne, Wyoming. We harvest the upstream feeds into our own lakehouse on each dataset's own schedule (nightly for permits and production headers, monthly for wells; the last unit harvest ran 2026-04-25), keep the silver views and a daily census of them, and serve deliveries from them. Jerry Ward runs the lakehouse and answers access requests.

Wells, permits, units and production come from Enverus feeds of state regulatory filings. The county index comes from the Enverus enhanced county clerk index. Each row carries its view and source update date.
