Attestly is a B2B API that turns a polygon and a ruleset into a compliance verdict. Send geometry, get back which protected areas it overlaps, how far it is from sensitive zones, whether the parties involved appear on sanctions lists — all in a single call.

​
What you can do

  • Check compliance: POST /v1/evaluate runs a ruleset (yours or from the catalog) over a polygon and returns a structured verdict — COMPLIANT, WARNING, NON_COMPLIANT, or DEGRADED.
  • Discover overlaps: POST /v1/intersections lists every reference area that intersects a polygon, with overlap area and ratio.
  • Measure distances: POST /v1/distance returns nearest features within a radius range.
  • Match a subject: POST /v1/subjects checks a typed identifier (CNPJ, EIN, OFAC SDN, etc.) against subject registers.
  • Browse the catalog: GET /v1/sources, GET /v1/rulesets to see which datasets and rulesets are available to your organization.

​
How it fits together

The discovery endpoints (/intersections, /distance, /subjects) answer raw questions about a geometry or identifier. /evaluate runs a full ruleset — your compliance policy expressed as a JSON document — and returns a structured verdict. Most customers start with discovery and move to /evaluate once their policy stabilizes.
