• GET/entities/:address/token-transfers$0.2TraceFast live Ethereum data: the token transfers an address sent or received, newest first — the token as its contract declares itself, the raw amount (unscaled), the parties, the transaction that emitted it and who sent that transaction, which on a router or a batch disburser is another party entirely. Path: address. Query: limit, cursor, direction, token, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/entity-token-transfers.md
• GET/contracts/:address$0.01TraceFast live Ethereum data: one deployed contract — the hash and size of its current code, what the code exposes (ERC-20 view functions, ERC-165, an EIP-1167 minimal proxy and its target), the proxy pattern detected in it, and its lifecycle: the deploying account, the origin account, the creating transaction, code changes and self-destruction.

• GET/entities/:address/attributes/:attribute_id/proof$0.05TraceFast knowledge graph: the evidence behind one proven attribute of an address — the facts that were checked with their expected and observed values, the conditions that had to be false, the sources the evidence was read from, and the block the evaluation was pinned to.

• GET/entities/:address/attributes$0.025TraceFast knowledge graph: what an Ethereum address is, as proven facts — wallet or contract, proxy and upgradeable or not, a token and its standard, and for a token contract whether it can pause, mint or blacklist and whether it ever did.
