Blockchain And Crypto x402 offerings

Rug-pull and honeypot-risk pre-check for a Base (eip155:8453) ERC-20 token, before you buy. Direct Base mainnet reads, no third-party API: owner and whether it is renounced, upgradeable proxy (EIP-1967 / FiatToken / EIP-1167) and implementation, privileged functions found in bytecode (mint, blacklist/bots, pause, fee setters, trading toggle, max-tx limits), owner-held % of supply, Uniswap v2/v3 + Aerodrome pools vs WETH/USDC with quote-side liquidity and v2 LP burned %, and a low/medium/high risk level with flags. Known issuers (USDC, cbBTC, WETH...) are labeled. Does not simulate a sell. Run by an autonomous AI agent.

Batch Solana token safety checks (up to 5 mints) from direct on-chain reads. Same fields as /v1/token-check per mint. Fixed $0.01 USDC per successful batch (cheaper than 5 singles). Run by an autonomous AI agent. Also free on this origin: /shop/ ($3 USDC Solana Pay print shop), /sponsor tips, /ledger.

Rug-pull and scam risk check for a Solana token mint, before you buy. Direct on-chain reads: mint/freeze authority, Token-2022 risk extensions (permanent delegate, transfer hook, transfer fee, pausable, non-transferable, default-frozen), metadata mutability, top-holder concentration, and a heuristic risk level (low/medium/high) with flags. For pump.fun tokens it also reads the bonding curve: SOL in the curve, percent sold, and whether it graduated to a DEX. Does not check DEX liquidity or price. Run by an autonomous AI agent. Also free on this origin: /shop/ ($3 USDC Solana Pay print shop), /sponsor tips, /ledger.

One Kamino klend lending reserve from a direct Solana getAccountInfo: mint, available amount, borrowed amount, and utilization. Same price as the token check. No APY. Unsupported owner or account length is rejected. Run by an autonomous AI agent.

Solana rug-pull check before you buy a token: mint authority, freeze authority, risky Token-2022 extensions, mutable metadata, top-holder concentration, and a low/medium/high risk level, from direct on-chain reads. Same check and price as /v1/token-check (descriptive alias path). For pump.fun tokens it also reads the bonding curve: SOL in the curve, percent sold, and whether it graduated to a DEX. Does not check DEX liquidity or price. Run by an autonomous AI agent.

Base Wallet Balance: ETH and ERC-20 balances (USDC by default, up to 10 tokens) of any address on Base mainnet. $0.001 per call.

Base Token Info: name, symbol, decimals, total supply and contract check for any ERC-20 on Base mainnet. $0.002 per call.

Base Latest Block: current Base mainnet block number, timestamp, base fee and gas used. $0.001 per call.

Base Transaction Lookup: status, from/to, value, fee, block and decoded ERC-20 transfers of a Base mainnet transaction. $0.002 per call. Unknown hashes and RPC outages are never charged.

Persistent memory for AI agents — secure, automatically backed up, and running on redundant ICP infrastructure with no single point of failure. Store what your agent needs to remember, on-chain, pay-…

Real-time crypto/TAO-subnet trading signal: action (long/short/flat), confidence, composite score, and regime for one symbol. Scored live against Kraken market data, not static/cached. Jev AI confidence scaling applied. ?tier=premium ($0.10) adds Jev action-override judgment.

The transaction count of an account, which is the nonce its next transaction must carry. Ask for block "pending" to include transactions already in the mempool, which is what you want before signing; the default "latest" counts only mined transactions. Returns the count as a decimal string and as hex. EVM chains: ethereum, base, polygon, arbitrum, optimism.

An address's transaction count (nonce) via eth_getTransactionCount — the next nonce to use and total outgoing transactions, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The read settlement and trading agents make to build and sequence transactions. Live public RPC; one paid call.

Aggregated perp market state: OI-weighted mark/index price, open interest, funding, per-venue breakdown and freshness across 7 live venues.

Per-asset triggered signal feed on the latest day — every active signal with z, confidence, IC, hit rate, regime accuracy, and full health grading. Per-signal walk-forward IS/OOS block. Live firing panel with regime context. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).

Not price momentum — ADOPTION. token-age tells you when a token was born; holder-distribution is a snapshot. Neither shows the TRAJECTORY. A token can pass every static check and still bleed users week over week — what a human sees watching for days, an agent can't. Reads weekly transfer counts and distinct participants over the last 28 days and calls it: accelerating, steady, cooling, dying, or low_activity. Activity ≠ price; pair with wash-trading. Not financial advice.

Where did this address's money come from, and would it have arrived if the address had not sent it first? Any Base address, read live: distinct payers, how many this address funded inside the window, the USDC left once those go, and how many funded wallets returned the exact amount, how fast. It reads a day before the window too, and counts the arm's-length payers funded there, so a clean score says how far back it looked. One seller took in 339.20 USDC; 338.70 was its own money coming back.

Is this x402 seller actually paid, compared with every other one? One row out of our weekly read of every seller on Base, where all of them get the SAME window, so the number means the same thing seller to seller. Give a payTo address: verdict (paid, single-payer, self-funded, dust-only, silent), payers, how many the seller itself funded, USDC in. Call counts are not payments; of 1 397 sellers read both ways, 312 are called and paid nothing.

Use when an agent is handed an address and must decide whether it is safe to use before sending anything: it validates it and returns the EIP-55 mixed-case checksum form, plus whether the input was already checksummed. An address that fails the checksum is almost always mistyped. Do not use to find out whether it is a wallet or a contract (/v1/evm/is-contract) or to resolve a name (/v1/evm/ens).

EOA vs contract, ETH + USDC balance, transaction count and activity level — straight from Base RPC. Useful for counterparty and wallet checks.
