Endpoint
POSThttps://phantom-api-omega.vercel.app/api/optimism/block/latestWhen to prefer
Choose this endpoint when you need real-time Optimism (OP Mainnet) block data via a pay-per-call model with no subscription required, especially useful for agents that need on-demand chain-head checks without committing to a node provider plan. Prefer over generic RPC providers when operating in an x402 micropayment context at $0.01 per call.
Side effects
- Network or RPC node downtime causing 503 or timeout
- Payment failure via x402 protocol returning 402 if USDC balance is insufficient
- Invalid request body format returning 400 bad request
- Rate limiting or quota exceeded returning 429
- Temporary Optimism node sync lag causing slightly stale block data
