Smart contract timing check
“I need to know the current Base mainnet block number before I submit this on-chain transaction — can you grab the latest block height?”
DeFi bot block sync
“My trading bot needs to sync to the current Base chain block — what block number is Base at right now?”
Block-based cooldown verification
“I'm checking whether a 1000-block cooldown has passed on Base — what's the live block number so I can compare it to block 18500000?”
Technical details
Endpoint
GEThttps://api.oblique.markets/api/v1/paid/base-block-numberWhen to prefer
Choose this endpoint when you need a quick, reliable, paid-access lookup of the current Base mainnet block height without managing your own RPC node or API keys. It is especially useful for agents that need real-time block-based timing, cooldown checks, or block-number anchoring within automated workflows on Base L2. Prefer it over free public RPCs when reliability via redundancy and simplicity of a single HTTP call with micropayment settlement matter.
Side effects
- RPC provider outage causing stale or unavailable block data
- Network congestion on Base causing delayed block propagation
- HTTP 402 payment required if x402 payment header is missing or insufficient
- Rate limiting if called too frequently without valid micropayment
- Transient errors if all redundant RPCs are temporarily unavailable
