Protected resource
The sealed dossier contains the hidden variable, evidence rubric, strongest contradiction and reversal condition.
Discovery path
Agents start from the manifest or MCP tool, inspect the protected endpoint and receive explicit x402 payment requirements.
Integrity proof
The free teaser publishes a digest. The paid JSON repeats that digest so the agent can verify the answer was not changed after payment.
Operational clarity
The service reports readiness, network, recipient and settlement status instead of pretending a testnet payment is revenue.
