wallet-portfolio-analysis

ETH and USDC balance of any address on Base, read live from the chain (eth_getBalance + USDC balanceOf) at request time. Pass ?address=0x... . Returns raw and decimal values plus the block number the read was made at. No third-party API, no cache.

Recent Ethereum event logs for a contract/address (bounded to the last 1000 blocks, not full-archive history).

Retrieves profile information associated with a blockchain address.

Read the ETH and USDC balance of any address on Base mainnet (chain 8453) straight from the chain, plus transaction count and how many x402 calls the USDC covers. Use it to check your own agent wallet before a paid workflow, to verify a cou

Wallet profile for an X1 address: every token it traded with XNT spent and received, realized and unrealized PnL per token and in total, top winners and losers, and a win rate. The win rate counts closed profit only, on positions of at least 0.1 XNT; positions still held at a loss are counted separately (heldAtLoss), so read it beside totalPnlXnt, never alone.

Screens a wallet address against OFAC's published SDN sanctions list (direct match only, Ethereum or Solana).

Base address snapshot: ETH balance, tx count, contract or EOA

TraceFast live Ethereum data: balanceOf(address) for one token at the end of a block, read from contract storage. A token outside the covered set is refused (422), never a fake zero. Path address and token: 0x-prefixed, 40 hex. Query block: integer, state at the end of this block, absent = current. Docs: https://docs.tracefast.xyz/api/address-token-balance.md

Wallet profile: funding source, network membership, exchange attribution, tags, and tokens created by this wallet.

TraceFast knowledge graph: address attributes of an Ethereum address — account nature, on-chain presence and derived traits. Path address: 0x-prefixed, 40 hex. Attribute dictionary: https://docs.tracefast.xyz/api/address-attributes.md

Base wallet snapshot at head: native ETH balance, nonce, is_contract. Optional ERC-20 balanceOf via ?token=. One 402, parallel RPC. No USD quote. Dead RPC is unread, not zero.

Historical trades for one wallet (path param: 0x… proxy-wallet address) plus a running win-rate & MODELED-PnL curve, computed ONLY from RESOLVED markets (modeled_pnl_usd is a MODELED estimate, NOT realized/settled P&L — it assumes a $1 binary payout per winning share, shares = size_usd ÷ entry price; not a substitute for on-chain settled P&L). Unresolved trades still appear (won: null, modeled_pnl_usd: null) but do not move the curve. Query param: window (30d|90d|all, default 30d — "all" is UNBOUNDED, window_days: null). The trades array is capped at 500 most-recent-first, but summary is computed over EVERY trade in the window (see summary.trades_returned / trades_capped), so the total matches this wallet's profile. 15 min delay. 404 (not charged) for wallets unknown to the Predge dataset. outcome_verified: {win_rate: true, pnl: false}.

Full profile of one Polymarket wallet (path param: 0x… proxy-wallet address, lowercase). Returns Predge score (0-100), win rates (live-computed 7d/30d from resolved markets + scorer's 30d/90d — outcome_verified: {win_rate: true, pnl: false}), all-time totals (trades, avg position, and modeled_pnl_30d_usd/modeled_pnl_all_time_usd — a MODELED binary-payout estimate over RESOLVED markets, all_time genuinely unbounded, matching the wallet-history curve; NOT realized/settled P&L, see the note field), top-5 favorite market categories, and the last 20 trades delayed 15 minutes. 404 (not charged) for wallets unknown to the Predge dataset.
