Discovery

Method Path Description
GET /oapif/ Landing document
GET /oapif/conformance Conformance declaration
GET /oapif/api OpenAPI definition

Collections (forms)

Method Path Description
GET /oapif/collections List form collections
GET /oapif/collections/{formId} Collection metadata + schema

Items (records)

Method Path Scope Description
GET /oapif/collections/{formId}/items read List records as GeoJSON FeatureCollection
GET /oapif/collections/{formId}/items/{recordId} read Single Feature
POST /oapif/collections/{formId}/items write Create Feature
PUT /oapif/collections/{formId}/items/{recordId} write Replace Feature
PATCH /oapif/collections/{formId}/items/{recordId} write Merge update Feature
DELETE /oapif/collections/{formId}/items/{recordId} write Soft-delete Feature

Query parameters (GET items)

Parameter Type Description
limit int Features per page (default 100, max 10000)
offset int Offset for pagination
bbox string minLng,minLat,maxLng,maxLat
bbox-crs string Supported: CRS84, urn:ogc:def:crs:OGC:1.3:CRS84, or full OGC CRS84 URL
datetime string ISO-8601 instant or interval (2026-01-01T00:00:00Z/..)
project_id string Filter by project
f string Output format: json or geojson

Invalid f or unsupported bbox-crs returns 400 validation_error.

Pagination and metadata

Responses include deterministic paging links and counts:

{
  "type": "FeatureCollection",
  "timeStamp": "2026-02-20T09:30:12.121Z",
  "numberMatched": 78,
  "numberReturned": 10,
  "features": [],
  "links": [
    {"href": "...?limit=10&offset=0", "rel": "self"},
    {"href": "...?limit=10&offset=10", "rel": "next"}
  ]
}

The gateway preserves relevant query params (bbox, datetime, project_id, f, bbox-crs) in generated links.

Create a feature

curl -X POST \
  -H "X-API-Key: mk_live_..." \
  -H "Content-Type: application/json" \
  "https://<ref>.supabase.co/functions/v1/api-gateway/oapif/collections/{formId}/items" \
  -d '{
    "type": "Feature",
    "geometry": {"type": "Point", "coordinates": [-6.75, 37.57]},
    "properties": {
      "name": "New Point",
      "project_id": "c328e46a-8fb9-41f1-a5f9-3dca9a894ab3"
    }
  }'

Notes:

  • Geometry must be valid GeoJSON.
  • Geometry payload is limited to 100KB.
  • If properties.project_id is provided, it must belong to the same organization.
  • System properties (_mapalyze_*) in input are ignored.

CRS

Responses include:

Content-Crs: <http://www.opengis.net/def/crs/OGC/1.3/CRS84>

All coordinates are CRS84 (WGS84 lon/lat).

Rate limiting

OGC endpoints follow the same API key limits documented in Errors & Rate Limits.
