Afferens is the data pipeline for AI agents — verified perception of the physical world through one hardware-agnostic API. Sign up, make a real perception call in 60 seconds, and build an agent that actually sees.
No signup, no code. Hit a modality and see the structured perception an agent gets back.
…Vision is live now. Spatial, acoustic, environmental & molecular are rolling out — same API shape.

}Things that are only possible because the agent can perceive — not toy apps anyone could ship with any tool.
A wearable/phone agent that perceives the scene and describes it out loud. Accessibility, travel, hands-free field work.
A robot/arm that perceives the scene and confirms the target before it moves. Closes the "agent hallucinated the action" gap.
A kiosk that reacts to what — and who — it sees, and holds a real conversation about it.
Point a camera, get structured stock + planogram data back as JSON.
Perceives hazards in a space and refuses to proceed until it reads clear.
Perceives the device in front of the user and guides the fix step by step.
Perceives defects on a line, flags and logs them with visual evidence.
Anything where 'the agent has to actually see the world' is the hard part. That's the bar.
