Obol blockchain data API

Bounded blockchain data on Base with x402 USDC payment. Verified route: GET /v1/base/network-status at 0.001 USDC, which returns the observed Base block height, block hash, chain id and a cross provider agreement check. At verification the returned block hash was matched against Base itself and was identical. The provider also lists address labels, sanctions screening, historical market data, address clustering and transaction lookups; those routes are listed but not payment verified. Base only.
