## 💡 Why Multi-Tiered x402?

- **Zero Signups & No API Keys:** No credit cards, accounts, or monthly commitments.
- **Pay-Per-Call Micropayments:** $0.005 to $0.080 USDC on Base L2 instead of $50–$100/mo SaaS subscriptions.
- **Context Compression Savings:** `/v1/digest` saves 80%+ on downstream Claude/GPT-4o token bills by summarizing 10,000 words into a dense 300-word structured brief on the edge.
- **Crypto Agent Security:** `/v1/audit` provides instantaneous scam, drainer, and contract safety checks before agents execute transactions.
- **Bypasses X API Paywall:** Query real-time Twitter sentiment and profiles without the $100/mo fee.
- **x402 V2 + Bazaar Standard:** Compatible with automated agent marketplaces (Agentic.market, LangChain, Coinbase AgentKit).
