Pricing

• Free tier: 1,000 calls per IP per day, no signup, no API key.
• Pay-per-call (x402): $0.002–$0.10 per call depending on complexity. Settled in USDC on Base or Solana via the x402 protocol — your client wallet pays automatically when you exceed the free tier.
• Coming soon — flat-rate API key tier: $49–$499/mo for credit-card customers who want predictable billing instead of per-call USDC settlement. Drop a note in GitHub issues if you'd be interested.
