All projects on Base matching “wallet balance”

Returns the native ETH balance and ERC-20 token balances of one Base wallet address, read live from Base mainnet at the latest block: USDC, WETH and the rest of the top 200 Base tokens by market cap, plus up to 50 token contract addresses named in the request. Each row carries the token symbol, name, decimals, raw amount and human-readable amount. Suited to checking a wallet's current holdings bef

Currency exchange rates and forex API: official ECB (European Central Bank) reference rates for ~30 currencies (USD, EUR, GBP, JPY, CHF, CNY...), any base currency, with currency conversion of an amount. Daily, no API key.

Run before sending ETH or USDC or paying gas, to confirm the wallet really has enough. Never trust a balance remembered from earlier in a chat. Reads a wallet's ETH and native USDC balance on Base directly from the chain, at one block.

Use when you need a wallet portfolio value in USD, a wallet net worth or token balances with USD value for a 0x address. Do not use for solana wallets, transaction history, NFTs, DeFi positions or long-tail tokens. Returns JSON with a wallet's USD value on Ethereum and Base in one call: native and major-token balances priced on-chain from Uniswap v3 pools on Base, per-chain totals and the tokens l

Get the ERC-20 token balance of any wallet on Base mainnet. Pass the token contract address and the holder address. Returns the raw balance, decimals, token symbol and the human-readable balance in one JSON response. Works for USDC, WETH, DAI or any standard ERC-20. Read-only, live on-chain data.

WalletForge wallet balance Base ETH USDC address

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

Quick ZK Auth v1.0.1 — Semaphore ZK wallet ownership on Base plus USDC balance attestation at snapshot block (not ZK-hidden balance in v1). ERC-8004 bundles with x402 payment binding.

Signed attestation (ECDSA plus a post-quantum ML-DSA-65 companion) of on-chain wallet conditions across 37 chains: token balance, NFT ownership, EAS, Farcaster, view calls, ratio rules, account code (plain key, EIP-7702 delegation, or contract), and agent standing (ERC-8004 registration, ERC-7710 delegation validity). A verifiable boolean, never raw balances or code. Up to 10 conditions per pay-pe

Recurring wallet monitor for crypto agents. Check balances and new USDC/ERC-20 transfers since the prior cursor, then return a ready next request. Designed to be called about every 60 seconds for deposit detection, payment monitoring and treasury alerts.

DeFi position and wallet risk snapshot on Base: token balances, account flags, and live Aave v3 collateral, debt, borrowing power, and health factor read directly from the protocol at a specific block, plus derived risk metrics — net equity, LTV utilization, leverage multiplier, health-factor band, and collateral drawdown tolerance (how far collateral can fall before liquidation). For agents asses

x402-preflight: confirm your wallet can transact, and see your balance, in one certified call. Pay $0.01 USDC on Base, get a signed on-chain-anchored receipt. The safe first transaction before you ship real volume.

Base wallet lookup / address research API: ETH + USDC balance with USD value (CoinGecko/Coinbase quotes), EOA or smart contract, nonce (tx count), gas base fee, ERC-20 token holdings and recent USDC inflows/outflows with counterparty count for any Base mainnet address. Wallet analytics, portfolio and onchain due diligence for agents. Live public RPC reads at request time; pay per call with x402 US

Crypto wallet screening: OFAC SDN sanctions check (refreshed daily) and a 0-100 risk score, with balances, activity and transaction-graph checks for EVM wallets.

Full unclaimed-crypto report for one wallet: which open airdrops, reward distributions, refunds and forgotten balances it can still claim (Uniswap 2020 UNI, Merkl on Ethereum/Base/Arbitrum/Optimism/Polygon, Doppler XDP, Drift recovery, CAPX, defunct-DEX ETH), with amounts, USD estimates, deadlines and official claim links. Read-only. Wallets with zero open claims are refused before payment.

Before your agent negotiates or shares data with another agent, make both prove they qualify. Open a channel with on-chain conditions (a USDC balance, a governance token, a verified attestation). Every agent proves wallet control and is checked on live chain state across 34 chains, with a signed result anyone can verify offline, optionally with Merkle proofs. Re-check on demand; whoever stops qual

Analyze a Base wallet address for on-chain wallet due diligence, transaction-history research, and risk triage. Returns native balance, transaction and token-transfer counts, first and last activity, contract status, a heuristic activity score, and risk flags as JSON. Not identity verification or a guarantee that an address is safe.

Deep risk scoring for a wallet before your agent pays it. Base: contract vs EOA, tx count, ETH balance, USDC balance, vanity patterns, zero/low activity. Solana: recent signatures, SOL balance, USDC token accounts, activity flags. Returns riskScore (0-1), label (low|medium|high|critical), flags[], metrics, and recommendation (safe_to_pay|review|avoid). Designed for agents that need to decide wheth

Preflight any address on Base or Arc before paying or approving it: EOA vs contract vs EIP-7702-delegated wallet, EIP-1967 proxy implementation/admin, owner(), Safe multisig threshold, ERC-20 metadata, USDC + native balance, Sourcify verification, and risk flags.

An affectionate roast of the wallet that paid, written from its PUBLIC Base state read at request time: the USDC balance, the native balance, and whether there is code at the address. Those become words — dust, pocket, purse, vault; gas or none; contract or plain — and a hand-written line is picked from them, keyed to your address and the UTC date, so it holds all day. EXACT AMOUNTS ARE NEVER RETU

On-chain snapshot for a Base address: contract vs EOA, transaction count, ETH balance, USDC balance, risk flags, and a simple recommendation (safe_to_pay | review | avoid). Use before your agent sends USDC to an unknown payTo wallet.

Pre-transaction counterparty check for an EVM wallet or contract: OFAC SDN screening, GoPlus malicious-address flags (phishing, drainers, laundering, mixers ...), and a live on-chain profile (EOA / contract / EIP-7702, nonce, balance, ENS, first transaction, contract verification). Returns risk_level, a plain recommendation (do_not_transact / review_before_transacting / no_red_flags_found), every

Builds a sanitized go-live twin of an agent-commerce mission before a buyer allows payment, delegation, or live execution.
