Each identifier maps to a documented REST endpoint and Postgres table in `blockdb_evm`. Prefix indicates the functional domain: * `01xx` — base chain primitives (blocks, transactions, logs, internal traces, contracts, function results) * `02xx` — token and pool metadata (ERC-20/721/1155, pools, fee terms) * `03xx` — reserves, swap prints, swap fees, transfers, flash loans * `04xx` — token-to-token OHLC, per-pool VWAP time buckets, pool yields (`0411`) * `05xx` — cross-pool token-to-token VWAP (aggregated across venues) * `06xx` — token-to-fiat (USD) VWAP * `07xx` — pool TVL in USD * `08xx` — arbitrage path definitions (`0801`) and path status (`0802`; same DDL family as `0801`) * `09xx` — arbitrage opportunities | Value | Table | Description | Notes | | ------ | -------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ | | `0101` | `blockdb_evm.b0101_blocks_v1` | Canonical block headers and integrity metadata. | [`POST /evm/raw/blocks`](/api-reference/evm/primitives/blocks) | | `0102` | `blockdb_evm.b0102_transactions_v1` | Executed transactions with gas, status, and calldata. | [`POST /evm/raw/transactions`](/api-reference/evm/primitives/transactions) | | `0103` | `blockdb_evm.b0103_logs_v1` | Event logs emitted by smart contracts. | [`POST /evm/raw/logs`](/api-reference/evm/primitives/logs) | | `0111` | `blockdb_evm.b0111_internal_transactions_v1` | Internal transactions (call traces). | [`POST /evm/raw/internal-transactions`](/api-reference/evm/primitives/internal-transactions) | | `0121` | `blockdb_evm.b0121_contracts_v1` | Contract deployments (CREATE/CREATE2), keyed by `contract_id`. | [`POST /evm/raw/contracts`](/api-reference/evm/primitives/contracts) | | `0122` | `blockdb_evm.b0122_function_results_v1` | Contract call return values versioned by block. | [`POST /evm/raw/function-results`](/api-reference/evm/primitives/function-results) | | `0201` | `blockdb_evm.b0201_erc20_tokens_v1` | ERC-20 token metadata. | [`POST /evm/entities/tokens/erc20`](/api-reference/evm/entities/tokens-erc20) | | `0202` | `blockdb_evm.b0202_erc721_tokens_v1` | ERC-721 collection metadata. | [`POST /evm/entities/tokens/erc721`](/api-reference/evm/entities/tokens-erc721) | | `0203` | `blockdb_evm.b0203_erc1155_tokens_v1` | ERC-1155 contract metadata. | [`POST /evm/entities/tokens/erc1155`](/api-reference/evm/entities/tokens-erc1155) | | `0211` | `blockdb_evm.b0211_liquidity_pools_v1` | Liquidity pool registry. | [`POST /evm/entities/pools`](/api-reference/evm/entities/pools) | | `0212` | `blockdb_evm.b0212_liquidity_pools_fee_terms_v1` | Versioned pool fee terms. | [`POST /evm/entities/pools/fee-terms`](/api-reference/evm/entities/fee-terms) | | `0301` | `blockdb_evm.b0301_liquidity_pools_reserves_v1` | Pool reserve / state snapshots.
