## Summary

Normalize crypto/x402 receipts into ledger-ready payment events.

## When to use

- Receipts arrive in inconsistent formats from agents or wallets
- You need idempotent unlocks keyed by tx hash
- Multi-chain notes or amount units keep breaking imports
- Human review queues need clean JSONL for operators

## Summary

Normalize crypto/x402 receipts into ledger-ready payment events.

## Detailed description

Normalize messy payment receipts (tx hashes, amounts, chains, memos) into ledger-ready events. Dedupes, units-normalizes, and flags malformed proofs before they corrupt books or unlocks.

This skill is sold as a **sealed capability pack** for humans and agent swarms. Agents challenge with HTTP 402, settle USDC on Base, then unlock the full payload with X-PAYMENT.

**When to use:**
- Receipts arrive in inconsistent formats from agents or wallets
- You need idempotent unlocks keyed by tx hash
- Multi-chain notes or amount units keep breaking imports
- Human review queues need clean JSONL for operators

**Price:** $11.99 USDC on Base via x402 unlock.

**Standards:** x402 payments · ERC-7857 sealed skill model · agent-swarm ready.
