Base URLhttps://mpp.tracefast.xyz/api/v1/chains/1

• GET/entities/:address/relations/:attribute_id/:object/proof$0.05TraceFast 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
• GET/contracts/:address/bytecode$0.01TraceFast 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
• GET/resolve$0.05TraceFast live Ethereum data: what a reference means. An address (`0x` + 40 hex) is described — the name TraceFast shows for it, how it presents it, what kind of address it is, its token identity. Query q: What to resolve: an address (`0x` + 40 hex, any case), or a name, ENS…; limit: 1..=20, default 10. Docs: https://docs.tracefast.xyz/api/entity-resolve.md
• GET/entities/:address/balance-history$0.02TraceFast live Ethereum data: the address's native balance at the end of each day it changed, oldest first, with the net change and the number of balance-changing events per day, the USD value at each closed day's last hour, and totals over the window. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query limit: Most recent days with a balance change to return, 1..=365, default 90. Docs: https://docs.tracefast.xyz/api/address-balance-history.md
• GET/entities/:address/relations$0.05TraceFast knowledge graph: the relations an address holds now — which implementation a proxy points at, which beacon it reads, who administers it, where an account has delegated, which lending market lists a token — as the subject (`direction=subject`: what it points at, default) or as the object (`direction=object`: who points at it). Path: address. Query: direction, attributeId, limit, cursor (see docs). Docs: https://docs.tracefast.xyz/api/address-relations.md
• GET/blocks/latest$0.01TraceFast live Ethereum data: the most recent block, with its header and the totals of what it contains — transaction counts by outcome, gas, fees, value moved, withdrawals. The same shape as `blocks/{number}`. Docs: https://docs.tracefast.xyz/api/block-latest.md
• GET/entities/:address/transactions$0.2TraceFast 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
• GET/consensus/queues$0.05TraceFast live Ethereum data: the validator activation and exit queues now, plus one closing point per UTC day for the most recent `limit` days (up to 90), newest first. Query limit: Most recent daily points to return, 1..=90, default 30. Docs: https://docs.tracefast.xyz/api/consensus-queues.md
• GET/entities/:address/relations/at-block$0.05TraceFast knowledge graph: the relations an address was the subject of at the end of one block — which implementation a proxy pointed at, which beacon it read, who administered it, where an account had delegated — each with the window it held for. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query block: The block to answer about. Docs: https://docs.tracefast.xyz/api/address-relations-at-block.md
• GET/entities/:address/attributes/history$0.05TraceFast knowledge graph: every attribute interval an address has held, oldest first — when it became a contract, when its code was removed, when it first held state. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query limit: 1..=500, default 100. Docs: https://docs.tracefast.xyz/api/address-attribute-history.md
• GET/tokens/:token/transfers$0.1TraceFast 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
• GET/transactions/:hash/storage-writes$0.2TraceFast 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
• GET/transactions/:hash/events$0.01TraceFast 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
• GET/tokens/stats$0.01TraceFast live Ethereum data: how many token contracts, transfer events and distinct holders the chain holds, in total and per standard (ERC-20, ERC-721, ERC-1155, ERC-777, ERC-4626). Recomputed daily. Docs: https://docs.tracefast.xyz/api/token-stats.md
• GET/consensus/validators/:index/withdrawals$0.05TraceFast live Ethereum data: the withdrawals paid out for one validator — block, global withdrawal index, the address paid and the amount — newest first, inside a block window of at most 216 000 blocks (about 30 days). Path index: The validator's index in the consensus registry. Query limit: 1..=100, default 25; cursor: `nextCursor` of the previous page; fromBlock: Inclusive lower block bound; toBlock: Inclusive upper block bound. Docs: https://docs.tracefast.xyz/api/validator-withdrawals.md
• GET/consensus/current$0.01TraceFast live Ethereum data: the validator activation and exit queues as of the newest sampled epoch — how many validators wait on each side, how much capital they hold, the churn rates, the trailing 7-day and 30-day averages, recent exit and deposit flow, and the active set's total effective balance. Docs: https://docs.tracefast.xyz/api/consensus-current.md
• GET/traces/:hash$0.2TraceFast 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
