Quantity Takeoff

Start here: Regulatory Radar — one bounded x402 compliance scan on Base. List price: $0.25. Inspect the live unpaid quote before signing; the quote is authoritative for this buyer. Other live carbon + compliance routes: • quantity-takeoff — $0.50 • ghg-ledger — $1.00 • disclosure-compiler — $2.00 • taxcredit-engine — $2.00 • regulatory-radar — $0.25 • regulatory-radar — $0.25 • hive — $5.00 • security-preflight — $1.00 • security-preflight — $1.00 • security-preflight — $1.00 • os-decisions — $1.00 • wu-wei-router — $1.00 • maxwell-defense — $1.00 No signup or API key. A caller receives HTTP 402, settles Base USDC, and gets the deterministic result. Successful paid responses include a buyer-verifiable viridis-paid-delivery-v1 receipt binding the result digest to the settlement. Buyer acceptance and usefulness remain unobserved. First paid call from a new wallet is $0.01. Live external proof: 4 settlement(s) from 4 distinct payer(s). Returning buyer? Put your public signing address in X402-Payer-Address on the unpaid preflight to receive the exact returning-wallet quote the first time. The hint never authorizes payment—never send a private key.
