Machine-native checks from $0.001 USDC

Start with a primitive

Check whether an AI interpretation differs from a human message; compare allowed versus not allowed permission values: Compare supplied values such as “allowed” and “not allowed.”

Check whether observed state differs from expected state; compare expected versus actual system state and enabled/disabled configuration values: Check supplied values such as “enabled” and “disabled.”

Current deterministic scope: exact normalized text equality returns 0; true/false, yes/no, enabled/disabled, present/absent, required/not required and allowed/not allowed return 1. Other inputs abstain before billing. This is not general language interpretation, diagnosis or a similarity score.

Try deeper capability when needed

Full-product validation cohorts may offer free completed validations only while their individual slots remain open and evidence requirements are met. Availability is unknown and requires manual review; S0.1 primitives are not free.

Eligible cohorts require two free completed validation transactions, supporting evidence, and manual evidence review before the full-product release gate.

Founding pricing applies only to the first 50 qualifying paid Product 001 full-capability transactions, subject to remaining cohort capacity, validation release and the existing contract.

Founding Product 001 pricing: $9 with pre/post context or $12 without, subject to qualification and the existing validation gate.

When a primitive flags a meaningful delta, choose the next deeper offer only if needed. Higher stages retain their own availability, pricing and validation gates.
