Resolve a federal award and buy bounded USAspending contract lifecycle and end-date evidence.

On-chain DeFi smart contract auditor, arbitrage scanner, and agent tollbooth via x402 on Base.

See who wins US federal contracts and grants (USAspending.gov). $0.02/call via x402.

What is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call with no parameters — the fastest way to test an x402 payment loop end to end. Positive-sum by design: it takes no parameters, so every agent shares one answer — $0.02 if you are the first inside the freshness window, $0.01 for everyone after you.

Is this address safe to send funds to on Base? Checks scam blacklists, address poisoning (look-alikes of your recent counterparties via ?from=), token contracts, burn and never-used addresses. Returns a verdict with reasons.

ERC-20 Balance and Metadata: Read one wallet balance for one ERC-20 contract on Base, Arbitrum or Optimism at a pinned block. Returns atomic amount, decimals, formatted balance, and symbol/supply if supported. No fiat valuation or token-safety conclusion. 0.01 USDC includes one bounded blockchain observation.

On-chain data query on Base, sold by Taifoon: the tokens and fee tier of a Uniswap V3 pool, or the hash of a block. An admitted data seller answers; Taifoon reads the same facts from the chain and grades the answer before you are charged. A failed answer is not charged. Answer + graded receipt. 0.03 USDC a call.

Celo ERC-20 risk check from live chain state. Returns a single verdict (LOW_RISK/CAUTION/HIGH_RISK, summary, oneLiner, reasons) plus market data (DexScreener/GeckoTerminal). Covers owner/renounced, paused, supply, known stablecoins (USDC, USDT, USAT, USDm), proxies (EIP-1967/1822/OZ/1167) with implementation analysis: verified source, risky selectors, upgrade authority (EOA vs Safe/timelock), forwarding to unknown targets. Use before accepting or paying in a token on Celo.

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 left unpriced for 0.005 USDC per call. Typical response time 5000 ms (p95). Category: Trading.

Use when you need a multi-chain wallet balance, a wallet portfolio or the recent transaction history of an address on Ethereum, Base or Solana. Do not use for uSD values, NFTs, DeFi positions, long-tail tokens or chains beyond Ethereum, Base and Solana. Returns JSON with a wallet's native and major-token balances on Ethereum, Base or Solana plus its latest transfers in and out, in one call, leaving airdrop spam out for 0.005 USDC per call. Typical response time 3000 ms (p95). Category: Data.

Korean public procurement law: rule-engine rulings, statutes search, live court precedents

Publish a deterministic claim about a Base proxy and let the market try to break it. You assert that a contract's implementation slot held one address across a block range, fund a reward for whoever finds a block where it did not, and Tereno writes the claim onchain and adjudicates counterexamples by historical storage reads. If nobody collects before your deadline, you get a reproducible survival receipt: not an audit, but proof the claim stood in public with money on it.
