MPP research
Standalone paid research, receipts, recovery, and refunds.
MPP is a separate pay-per-report access model athttps://mpp.deepsearch.app/v1/research. It uses a payment credential and its configured price, defaulting to $0.90, instead of an account API key. Research is limited to public-source briefs; the seven account-based lookup operations keep their existing access boundaries.
The source SDKs accept caller-owned payment transports throughmppResearch and mpp_research. Retain the credential and receipt: retry the same credential with identical inputs to recover its saved report for 30 days. Different inputs conflict. A partial report is explicit. Failed Stripe research enters the privileged refund worker; Tempo refunds use an auditable operator queue. Follow the gateway setup before attempting a payment.
