AI agents can now hire humans on Arc to capture ground-truth 3D models of the physical world. @vangrid_io An agent posts a USDC bounty. A person films the location with a phone. Vangrid reconstructs it into a textured mesh with cryptographic provenance and returns it through the same API. Settlement happens in under a second on a chain designed for agent-run businesses. Satellites miss stairwells, loading bays, and warehouse interiors. This closes that gap with real, human-captured spatial data paid for autonomously. First physical-world service agents can buy on Arc. The loop from software intent to physical observation is now open.
