API access
Your AI client reaches Texas Statewide Parcels through one ParcelOps MCP endpoint, so there is no separate key to hold for it and no per-source client to write. Reaching it takes no credentials of your own.

What this source cannot tell you
- ⚠ Anything outside Texas statewide. A request past that edge comes back empty rather than approximated.
- ⚠ Which years it spans, because the covered period is not declared.
- ⚠ Anything Texas Geographic Information Office StratMap does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
- ⚠ The statewide common schema is narrower than many county appraisal-district systems.
- ⚠ Confirm title and boundaries with the county appraisal district or recorded instruments.
- ⚠ Prop_ID (parcelId) is assigned per county appraisal district, not statewide, and this layer publishes no county column to scope it by; a parcelId match spanning more than one county is disclosed as parcelIdCollision.
