Proof of Spend · Your statement

A bill you can check.

Every charge below is committed to a hash-chained receipt, under a spending limit you signed yourself. The total is simply their sum, recomputed in your browser, not asserted by us. Prices stay private: the chain proves the charge without publishing what you paid.

Use every provider through one endpoint with no API keys of your own. You set the ceiling and sign it with your Passport key, we can never bill past a limit you didn’t authorize, and you can prove it.

Why this is different

Every other gateway shows you a number and asks you to believe it. Here the number is derived from evidence you can inspect: each charge is a commitment inside a tamper-evident chain, and the ceiling is an attestation carrying your own signature. Verification runs client-side. View source to read it (Ctrl+U on desktop; use your browser’s “View page source” on mobile).

# Open any commitment yourself:
#   billing_hash == SHA-256( JSON{cost_usd, mandate_id, nonce, tokens_in, tokens_out} )
# where billing_hash lives in the public receipt:
curl -s https://api.omnistrat.ai/api/decision/verify/<receipt_id>
# and cost/nonce come from this authenticated statement.
# Prices are never public. Only you can open a commitment.
