- 78trustContracts BytecodeTraceFast
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
$0.005per call on Base100% uptime, 113 ms, 1 paying agentsPassing, checked 20 min ago - 78trustChains BlocksTraceFast
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
$0.005per call on Base100% uptime, 292 ms, 1 paying agentsPassing, checked 43 min ago - 77trustAttributes HistoryTraceFast
TraceFast 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
$0.025per call on Base100% uptime, 396 ms, 2 paying agentsPassing, checked 2 h ago - 77trustContracts ProxyTraceFast
TraceFast live Ethereum data: the implementations a proxy contract has been observed delegating to — from its EIP-1167 bytecode, its EIP-1967 implementation or beacon slot, or its OpenZeppelin v1 slot — newest first, each with the blocks it was seen at and whether it has since been replaced. Path address: The proxy contract address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/contract-proxy.md
$0.01per call on Base100% uptime, 338 ms, 2 paying agentsPassing, checked 2 h ago - 77trustEntities Balance HistoryTraceFast
TraceFast 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
$0.01per call on Base100% uptime, 304 ms, 2 paying agentsPassing, checked 2 h ago - 77trustEntities Daily ActivityTraceFast
TraceFast live Ethereum data: for each day in a window, how many blocks changed the address's own account state and which kind of change it was (balance, nonce, code, creation). Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query period: `30d`, `90d` (default) or `365d`. Docs: https://docs.tracefast.xyz/api/address-daily-activity.md
$0.01per call on Base100% uptime, 337 ms, 2 paying agentsPassing, checked 2 h ago - 77trustConsensus CurrentTraceFast
TraceFast 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
$0.005per call on Base100% uptime, 354 ms, 2 paying agentsPassing, checked 2 h ago - 76trustRelations HistoryTraceFast
TraceFast knowledge graph: every relation interval an address has held, oldest first — as the subject (`direction=subject`: what it pointed at, default) or as the object (`direction=object`: who pointed at it). Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query direction: `subject` (default) or `object`; limit: 1..=500, default 100. Docs: https://docs.tracefast.xyz/api/address-relation-history.md
$0.025per call on Base96.4% uptime, 302 ms, 2 paying agentsPassing, checked 2 h ago - 75trustEntities Internal TransfersTraceFast
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
$0.1per call on Base100% uptime, 331 ms, 1 paying agentsPassing, checked 6 min ago - 75trustContracts EventsTraceFast
TraceFast live Ethereum data: the event logs a contract emitted, newest first, each with its topics and data and, where the signature is known, the decoded event and its arguments. Path address: The contract address, `0x`-prefixed, 40 hex characters, any case. Query: limit, cursor, topic0, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/contract-events.md
$0.1per call on Base100% uptime, 302 ms, 1 paying agentsPassing, checked 31 min ago - 75trustChains ResolveTraceFast
TraceFast 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
$0.025per call on Base100% uptime, 329 ms, 1 paying agentsPassing, checked 29 min ago - 31trustBlocks LatestTraceFast
TraceFast 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
