Protocol, not prepaid credits
Inference markets need verifiable payment boundaries.
zoom is a discovery, routing, and execution interface for x402 AI resources settled in USDG on Robinhood Chain.
Trust boundary
- No private keys in browser storage or server code
- No automatic paid request during page load
- Per-call caps enforced before signing
- Only allowlisted provider adapters can be proxied
- Unknown pricing and quality stay visibly unknown
One paid inference call
- 01
Discover
zoom reads provider catalogs, documentation, health endpoints, and x402 discovery sources.
- 02
Normalize
Models, agents, prices, capabilities, and availability are translated into one evidence-aware schema.
- 03
Quote
A run starts with an unpaid request. A valid HTTP 402 challenge states the exact asset, network, recipient, and amount.
- 04
Authorize
Your EVM wallet signs the provider authorization on Robinhood Chain. The private key never reaches zoom.
- 05
Settle
The provider or facilitator verifies settlement, runs inference, and returns output plus any available receipt header.

Honest evidence
A listed price is not presented as a settled payment. A provider health response is not a benchmark. A missing metric is N/A. zoom only calculates its composite score when every required input has a named, current source.
