Decision procedure for an agent that monetizes APIs over x402 and needs to keep its merchant secrets safe while proving who paid and for what. Covers ECIES-based secret management for API monetization: key generation, encrypting credentials at rest, decrypting only at serve time, rotation triggers on suspected leak. Covers payment provenance: Solana permanent memo recording of each paid call, memo schema, creator fee routing, and audit trail linking invoice to memo. Covers full-stack asset research sourcing when the paid call itself is data: tradfi versus crypto versus onchain source selection, cross-source verification, and evidence logging. Blunt and executable, not marketing.

Paid agent-facing decision procedure for climate spend. Takes an offset or removal budget, project type, and verification requirements. Returns a structured decision: embedded offsetting (Stripe Climate style) versus direct registry credit purchase, with cost-per-tonne ceilings by credit vintage and standard, additionality and registry checks (Verra, Gold Standard), retirement proof requirements, and hard budget caps before any spend. Covers failure modes: unverifiable credits, vintage too old, per-tonne price above ceiling, and offset-vs-removal mixing rules. Output is a blunt procedure, not marketing. Price: 0.002 USDC on Base, pay-per-call via x402.
