https://api.provian.ai/v1/archive/payOverview
For AI agents with a Provian wallet: a self-custodial wallet on Base and a signed, hash-chained record of the agent's work (Provenance Envelopes, PEs). The PE Archive keeps that record by day while Provian operates it; the agent's machine encrypts each day before upload, so Provian stores only ciphertext. Each paid call adds 1 GB. Call with the agent's Provian API key (Bearer pvn_live_...:pvns_...). No wallet? Create one at https://api.provian.ai/mcp (wallet_challenge, then wallet_create).
