eth_getFilterLogs

eth_getFilterLogs returns the full set of logs matching a log filter you already created on Polygon PoS (chain ID 137), independent of how many times you have polled it. Where eth_getFilterChanges hands back only the delta since your last call, this method ignores poll state and replays everything the filter's address and topic criteria match. On Polygon — the EVM-equivalent, MATIC-fee network behind QuickSwap, Aave, and the bulk of on-chain USDT/USDC activity — that makes it the right call to seed an indexer with a filter's complete event history. Send it to https://polygon.therpc.io/YOUR_API_KEY with the filter ID and you get an array of every matching log object.

Use cases

• On application start, load a filter's complete historical log set in one shot — for example every Transfer from a Polygon token contract — before switching to incremental eth_getFilterChanges polling.
• After a service restart, replay all events the filter has matched so far by calling eth_getFilterLogs once, then resume the delta loop with eth_getFilterChanges so nothing emitted during the downtime is missed.

Errors & troubleshooting

Common pitfalls

• Unlike eth_getFilterChanges, this returns every matching log, not just new ones — on a busy Polygon contract a wide filter can return a very large result set and may hit the 10000-result cap.
• It only accepts log filters created with eth_newFilter; passing a block filter or pending-transaction filter ID returns an error.
• Filters expire after about five minutes of inactivity, so call eth_getFilterLogs promptly after creating the filter rather than letting it sit idle.
