Research Preview — This API is under development.

Intersects

Check if two geometries intersect (share any portion of space).

POST /compute/v0/intersects

Request Body

chainId · number · required

Target chain ID (e.g., 84532 for Base Sepolia, 8453 for Base).

geometry1 · Input · required

First geometry to check.

geometry2 · Input · required

Second geometry to check.

schema · string · required

EAS schema UID to issue the attestation against.

recipient · string

Ethereum address to receive the attestation. Defaults to zero address if not provided.

Example Request

curl -X POST https://api.astral.global/compute/v0/intersects \
  -H "Content-Type: application/json" \
  -d '{
    "chainId": 84532,
    "geometry1": "0xpolygon1...",
    "geometry2": "0xpolygon2...",
    "schema": "0xschema...",
    "recipient": "0xdef456..."
  }'

Example Response

{
  "result": true,
  "operation": "intersects",
  "timestamp": 1706400000,
  "inputRefs": [
    "0xpolygon1...",
    "0xpolygon2..."
  ],
  "attestation": {
    "schema": "0x...",
    "attester": "0x...",
    "recipient": "0xdef456...",
    "data": "0x...",
    "signature": "0x..."
  },
  "delegatedAttestation": {
    "signature": "0x...",
    "attester": "0x...",
    "deadline": 1706403600
  }
}

Notes

• Uses PostGIS ST_Intersects function
• Returns true if geometries share any space (including boundaries)
• More permissive than contains — touching boundaries count as intersection
