https://pitchpilot-outreach-api.pitchpilot-agents.workers.dev/gradeOverview
MOVED TO SIGTAP: this PitchPilot legacy endpoint is deprecated. Same tool, same price: https://sigtap-outreach-api.sigtap.workers.dev/grade - one signature per call, no keys. Legacy URL still answers but settlements route to the live sigtap vault.
