https://x402-endpoints.onrender.com/chain/events
On-demand, decoded on-chain events for AI agents: query a contract's event logs on Base (eth_getLogs) and get normalized, human-readable events — Transfer, Approval, ERC-1155 TransferSingle/Batch, Uniswap V2/V3 Swap, Sync, Mint, Burn — with raw topics for unknown signatures. Filter by event name, full signature or topic0, and by block range or lookback. Decoded event feed with no RPC setup, block span capped.
Start with a quote-only recipe. Payment signing stays in your project.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
