M2MCent Web3 Smart Contract Indexer MCP Node

Choose this endpoint when you need a quick boolean check against a web3 smart contract index on Base L2 and can tolerate a minimal true/false response without additional context. Prefer alternatives if you need detailed contract data, event logs, or structured multi-field responses, as this endpoint only returns a boolean.

• Payment failure if USDC balance is insufficient for x402 micropayment ($1.39 per call)
• Empty or malformed text input may return false negatives
• The boolean response schema is minimal — no detail on why result is true/false
• High-volume sibling endpoints with identical schemas suggest auto-generated stubs with uncertain data quality
• Node may be offline or the subdomain unreachable, returning a network error
