Endpoint
GEThttps://store.agentexchange.work/chain/block-numberWhen to prefer
Use this endpoint when an AI agent needs the current block number for an EVM-compatible chain without managing API keys, subscriptions, or RPC node infrastructure. Particularly useful in x402-enabled agent workflows where micro-payments per call are preferred over monthly billing. Supports 6 major EVM chains in a single unified API.
Side effects
- Unsupported chain value returns an error — only base, ethereum, optimism, arbitrum, polygon, gnosis are valid
- Payment not included or insufficient USDC triggers HTTP 402 Payment Required
- Network or RPC connectivity issues may result in a 5xx error
- Default chain is Base if no chain query param is provided
