What's metered
API-PAY-PER-CALL bills per token, priced at $0.0001 per token, confirmed by the live endpoint. Anything smaller than a normal invoice line becomes chargeable on its own.
What the receipt covers
Each signed receipt binds the request ID, the model that ran, and the token count actually billed, so the invoice for an inference call is provable rather than asserted.
The Circle complement
Circle's flow proves the USDC authorization for the call was valid. It says nothing about which model answered or how many tokens it used. Hive's receipt covers that side: it signs what the API actually delivered for the tokens billed. Circle Nanopayments enables gas-free USDC transfers as small as $0.000001 by batching offchain authorizations into one onchain settlement, per Circle's Nanopayments documentation. It runs live on mainnet across 11 EVM chains, per Crowdfund Insider. Hive has no relationship with Circle. This describes their public protocol and where a receipt sits next to it.
