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 current runtime bytecode of a contract as hex, with its code hash and a structural fingerprint that is equal across contracts sharing the same logic. Up to 24 576 bytes of code. An address with no indexed code answers 404. Path address: The contract address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/contract-bytecode.md

TraceFast live Ethereum data: every EIP-7702 authorization-list entry carried by the transactions of one block — the delegation target, the chain id and nonce it was signed for, and the signature — in transaction order and then list order. Path number: Block height. Query limit: 1..=100, default 25; cursor: `nextCursor` of the previous page. Docs: https://docs.tracefast.xyz/api/block-authorizations.md

Render any URL or HTML as a PDF. Supports custom paper size, margins, landscape, and background printing.

TraceFast live Ethereum data: the validator withdrawals paid out in one block — index, validator, recipient and amount — in withdrawal-index order. A block holds at most 16. Optionally narrowed to one validator or one recipient. Path number: Block height. Query: limit, cursor, validatorIndex, address (see docs). Docs: https://docs.tracefast.xyz/api/block-withdrawals.md

TraceFast live Ethereum data: every account whose own state — native balance, nonce or code — changed in one block, with what changed and the balance before and after, in address order. Path number: Block height. Query limit: 1..=100, default 25; cursor: `nextCursor` of the previous page. Docs: https://docs.tracefast.xyz/api/block-addresses.md

TraceFast live Ethereum data: the event logs a transaction emitted, in emission order, each with the emitting contract, topics and data, and — when the event signature is known — the decoded event name and arguments with a stated confidence. Path hash: Transaction hash, `0x`-prefixed, 64 hex characters, any case. Query limit: 1..=100, default 25; cursor: `nextCursor` of the previous page. Docs: https://docs.tracefast.xyz/api/transaction-events.md

TraceFast live Ethereum data: the transfer events of one token contract, newest first — the parties, the raw amount (unscaled) or token id, the event kind, the transaction that emitted it and who sent that transaction, which on a router or a batch disburser is another party entirely. Path: token. Query: limit, cursor, from, to, eventType, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/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 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

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: 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

Create an email validation job from a JSON list of addresses or CSV text (send exactly one). Poll its status, then fetch results as JSON or CSV. Billing counts only testable addresses, fixed at creation; unreachable, disposable and typo domains are free.

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).
