TraceFast live Ethereum data: one block by height — its header (hash, parent, roots, fee recipient, gas, base fee, blob gas) and the totals of what it contains: transactions by outcome, contract creations, blob transactions, logs, withdrawals, value moved, fees burnt and paid. Path number: Block height. Docs: https://docs.tracefast.xyz/api/block.md

TraceFast live Ethereum data: one token contract — its standard as observed from its events (`erc20`, `erc721`, `erc1155`), the symbol, name and decimals it declares (verbatim, not verified), its all-time transfer count and, where indexed, its all-time distinct holder count. Path token: The token contract address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/token.md

TraceFast knowledge graph: the evidence behind one proven relation between two addresses — the facts checked with their expected and observed values, the conditions that had to be false, the sources read, and the block the evaluation was pinned to. Path: address, attribute_id, object. Docs: https://docs.tracefast.xyz/api/address-relation-proof.md

TraceFast 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

Opens each URL in a cloud browser and returns one tab per URL, in input order, with the title, content type, extracted text, the accessibility tree and a link map. Results over the inline size limit return a preview per tab plus a download reference. Each call is one request.

TraceFast live Ethereum data: the transactions an address sent or received, newest first — each with sender, recipient, value, fee, the called function where its selector is known, the receipt's outcome, and which side of it this address is on (`sender`, `receiver`, or `self` when it is both). Path: address. Query: limit, cursor, direction, status, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/entity-transactions.md

TraceFast live Ethereum data: every contract storage slot a transaction wrote, in execution order — which contract's storage, which frame wrote it (with the address whose code ran, which on a `delegatecall` is not the storage owner), the slot, the value written, and the value the slot held before where that can be established. Path: hash. Query: limit, cursor (see docs). Docs: https://docs.tracefast.xyz/api/transaction-storage-writes.md

TraceFast live Ethereum data: the whole call tree of a transaction, frame by frame in the order it ran, paged — no 1 000-frame cap. Path hash: Transaction hash, `0x`-prefixed, 64 hex characters, any case. Query limit: 1..=100, default 50; cursor: `nextCursor` of the previous page. Docs: https://docs.tracefast.xyz/api/trace-frames.md

TraceFast live Ethereum data: every call frame a transaction executed, the order it ran — the caller and target of each, the kind of call, the value and gas it moved, its own outcome, and why it reverted where it did. Path hash: Transaction hash, `0x`-prefixed, 64 hex characters, any case. Query: includeCalldata, limit (see docs). Docs: https://docs.tracefast.xyz/api/trace.md

TraceFast live Ethereum data: the value-carrying call frames an address sent or received inside transactions, newest first — each with its position in the call tree, its depth, the kind of call, the value it moved and its own outcome. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query: limit, cursor, direction, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/entity-internal-transfers.md
