Pricing

Pay for coverage, not verdicts.

The self-check, the report pages, the badges, and the open harness are free forever. What you pay for is scale: watching more, turning it around faster, and keeping a whole network graded over time.

Money buys speed, coverage, and tooling. It never buys a grade, or a better one. Every grade is reproducible by re-running the open harness, so a paid result is falsifiable. Nobody can pay for a grade.

Self-serve payments settle in $POLYGRAPH on Base. Enterprise engagements are invoiced. Prices for the paid MCP-security market sit under the incumbents: vendor-risk platforms charge from $79 per vendor per month for shallower, non-reproducible signals.
