FREE, read-only. Integrity-sealed decomposition of x402 payment growth on Base from SmartFlow Observatory's independent ledger of USDC micro-transfers: how much of the headline volume is wash / self-dealing / clone-fleet activity vs bundler plumbing vs the organic clean core. Returns the full dataset plus seal_verified (this client recomputes the SHA-256 seal locally, recipe included in the response) and data_age_hours. Use this BEFORE trusting any headline x402 volume figure. Caveats: data refreshes roughly daily (check data_age_hours); figures reflect the observatory's ingest time, so the most recent ~1h of activity may be under-represented.

Creates a PAYABLE ORDER for a $399 signed, human-reviewed audit of an x402 endpoint or receiving wallet (wash-share, payer concentration, demand dispersion, attribution), delivered by email within 48 business hours of payment. COST: calling this tool is free and moves NO funds. It returns an x402 exact-scheme payment challenge (HTTP 402) with a per-order UNIQUE USDC amount on Base, plus plain-language payment instructions and the order id. The purchase only happens if you (or your operator) then pay the EXACT quoted amount to the quoted address; do not round it. This is a real $399 purchase; confirm with your operator if your spend policy requires it. Unpaid orders are harmless and expire on their own within 24h. After paying, poll get_audit_order_status with the order id; if a payment submission times out, poll status BEFORE paying again. Never pay the same order twice.

FREE, read-only. Poll the status of an audit order created with order_endpoint_audit. Status pending_payment means the exact-amount USDC payment has not been detected yet; paid: true confirms your x402 payment was matched; a delivered state means the signed report was emailed. Caveats: payment detection reads Base USDC transfer logs and can lag a few minutes behind the chain. If you just paid the exact amount, wait 2-5 minutes and poll again before assuming a problem. Unpaid orders expire within 24h.
