Perception shouldn’t be computed.
It should be shared.
Colpero is the economic layer for shared spatial perception. Robots discover, pay, and query physical space over HTTP, settled in USDC. No tokens. No accounts. No sessions.
80% of robotics compute is spent on perception, not action.
Every drone, every forklift, every delivery bot runs its own SLAM on the same warehouse. The map is rebuilt from scratch, thousands of times a day, by machines that will never share what they learned.
Three steps. One round-trip.
Discover
A domain node publishes its capabilities to an on-chain registry on Base Sepolia. Robots query the registry by capability, not by URL.
Pay
The robot hits the node. The node replies 402 Payment Required with an x402 envelope. The robot signs a USDC transfer and retries.
Perceive
The node runs the spatial query (distance, nearest, path, semantic retrieval) and returns 3D coords. Same TCP round-trip. Sub-cent cost.
The 402 Payment Required status code, weaponized. A client retries a failed request with a signed USDC envelope in the X-PAYMENT header. The server settles on-chain and returns the real response. No sessions, no API keys, no accounts.
Colpero's registry contract is inspired by the emerging ERC-8004 standard for on-chain agent identity and reputation. Full compliance is on the roadmap — we ship what works today and track the standard as it solidifies.
No token. No staking.
No governance forum.
Tokens couple a network’s value to speculation. They tax every new operator with a cold-start problem: you have to acquire the token before you can earn.
Colpero settles in USDC because USDC is what robots can already hold. The network grows by being useful, not by being held.
Real numbers. Not a mockup.
Pulled from GET /nodes and GET /metrics at request time. If a number is zero, it says zero.
