# Polygon methods
> Complete reference of supported Polygon PoS JSON-RPC methods on Chainstack, including eth, debug, trace, and bor namespace availability details.
Our pricing is simple: 1 RU per full request, 2 RUs per archive. For which EVM methods are full vs archive, see [Request units — EVM methods affected by block age](/docs/request-units#evm-methods-affected-by-block-age).
See also [interactive Polygon API call examples](/reference/polygon-getting-started).
Polygon runs on the Bor client, which does not implement the Erigon-only Parity `trace_*` or `erigon_*` namespaces. Migrate the `trace_*` methods to their `debug_*` equivalents:
| Parity `trace_*` method | Replacement on Bor |
| -------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `trace_transaction` | [`debug_traceTransaction`](/reference/polygon-tracetransaction) with `flatCallTracer` |
| `trace_block` | [`debug_traceBlockByNumber`](/reference/polygon-traceblockbynumber) with `flatCallTracer` |
| `trace_call` | [`debug_traceCall`](/reference/polygon-tracecall) with `flatCallTracer` |
| `trace_filter`, `trace_replayBlockTransactions`, `trace_replayTransaction` | [`debug_traceBlockByNumber`](/reference/polygon-traceblockbynumber) with `flatCallTracer` per block, or [`eth_getLogs`](/docs/understanding-eth-getlogs-limitations) for event ranges |
Pass `flatCallTracer` (`{"tracer":"flatCallTracer"}`): it returns traces in the same Parity flat format as the old `trace_*` methods, so it is the closest drop-in replacement. The `erigon_*` convenience methods have no Bor equivalent — use the standard `eth_*` methods instead.
On Bor, `eth_getProof` returns state proofs only for roughly the latest 128 blocks; historical proof queries are not available.
