FAHCE Integrity Repair — Kingan Logic

Check an AI-generated answer against caller-supplied evidence before relying on its claims.

Service
FAHCE performs bounded deterministic integrity analysis. It identifies unsupported claims, contradictory records, missing evidence and unsupported assertions of completed actions. Results may include diagnosis, a proposed bounded repair, verification state and a content-hashed receipt.

Operations
- Diagnose: POST https://fahce.kinganlogic.com/api/v1/diagnose — $0.15 fixed.
- Repair: POST https://fahce.kinganlogic.com/api/v1/repair — $0.15 fixed.
- Verify: POST https://fahce.kinganlogic.com/api/v1/verify — $0.15 fixed.
- Repair Bundle: POST https://fahce.kinganlogic.com/api/v1/repair-bundle — up to $0.39; eligible actual settlement $0, $0.15 or $0.39.

Payment
x402 v2, USDC on Base mainnet (eip155:8453). The three individual operations use exact. Bundle uses upto and Permit2. No pre-issued FAHCE API key or human account is required for eligible paid REST requests.

Bundle buyers must check USDC balance, Permit2 allowance and, when initiating a standard ERC-20 approval, the Base ETH required for transaction fees. Do not assume gas sponsorship is supported unless the facilitator advertises and supports it.

Read the published legal policies. Include the required FAHCE-Terms-Accepted header with the current legal_documents.publication_hash.

Response custody
Retain the entire JSON response, not merely its billing summary. The nested receipt contains integrity hashes. Preserve the separate gateway PAYMENT-RESPONSE, the purchase request identity, and the confidential receipt-recovery credential. A hash alone does not authorize recovery.

Unknown payment or delivery status requires reconciliation, not another automatic purchase.
