How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
Returns a JSON object with an 'ok' boolean indicating success, a 'height' integer representing the current block number, and a 'product' string identifying the endpoint ('block'). Optionally scoped to BSC, Base, or both networks depending on the 'network' query parameter.
Example use cases
Real-time Base block monitoring
“Can you grab the latest block height on the Base network for me? I need to know how far along the chain is right now.”
Cross-chain block sync check
“Fetch the current block height for both BSC and Base at the same time so I can compare where each chain is.”
BSC block height snapshot
“What's the current block number on Binance Smart Chain right now? Just give me the latest height.”
Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/v1/blockWhen to prefer
Use this endpoint when you need a lightweight, real-time block height lookup for BSC or Base (or both) and are operating within an x402 micropayment workflow. Ideal for agents that already handle x402 payment headers and need cheap ($0.01 USDC), on-demand blockchain state checks without requiring a full RPC node connection or a heavier blockchain data provider.
Side effects
- Missing or invalid x402 payment header returns HTTP 402 Payment Required
- Invalid network enum value returns a validation error
- Payment on unsupported network (non-Base for v2) may be rejected
- Cloudflare Worker downtime returns 5xx errors
- Querying both networks may return partial data if one chain RPC is degraded
