Blockchain And Crypto x402 offerings

Total value locked for a DeFi protocol (aave, uniswap, aerodrome, lido...) and/or a chain (Base, Ethereum, Solana...), with the chain's TVL rank.

Quick AI token verdict: a 2-3 sentence plain-English risk summary plus risk level and red flags for any token on Base, Ethereum, Polygon, Arbitrum, Optimism or Solana. Built on honeypot sell simulation and tax checks (EVM) or mint/freeze authority and holder concentration (Solana). Half the price of the full report.

Token risk report with a plain-English AI verdict for any token on Base, Ethereum, Polygon, Arbitrum, Optimism or Solana. EVM: honeypot sell simulation, buy/sell tax, verified source, upgradeable proxy, owner, supply, holders, main pool liquidity, price and 24h change, plus a low/medium/high/critical risk rating.

Metadata for any Solana token mint or NFT: name, symbol, image, description, supply, decimals, price and market cap, mint and freeze authority (can more be minted? can accounts be frozen?), owner, royalties and creators.

Solana token risk report (rug check) for any SPL or Token-2022 mint: mint and freeze authority, top-holder and developer concentration, serial-launcher check, Jupiter suspicious flag, liquidity, pool age, organic trading score, holders, price and market cap, a low/medium/high/critical rating and a plain-English AI verdict.

Multi-chain wallet portfolio: every token a wallet holds on Ethereum, Base, Arbitrum, Optimism and Polygon (or Solana) with live USD prices, value per token and per chain, and the total. Spam tokens without a price are filtered out.

Live crypto prices with 24h change and market cap. Pass symbols (btc,eth,sol) or CoinGecko ids, up to 50 coins, in up to 10 currencies (usd,cad,eur...).

Agent mailbox: send a message to any AI agent by its wallet address and read your own inbox. The sender is the verified paying wallet, so agents can coordinate without accounts. Also callable as GET with the same fields as query parameters.

x402 endpoint checker: tests any paid x402 URL for a correct 402, price and networks, pay-to address, discovery metadata, CORS, response time and Coinbase's validator, and lists every issue to fix.

Solana wallet balances in one call: SOL and every SPL token with USD price and value, total portfolio value, plus NFT and compressed NFT counts.

Perpetual futures market data from Hyperliquid: mark and oracle price, 24h change, hourly and annualized funding rate, open interest, 24h volume, premium and max leverage. Pick coins or get the top markets by volume.

NFT lookup on Ethereum, Base, Polygon, Arbitrum or Optimism: collection name, symbol, standard and supply; with token_id also the current owner and resolved metadata (name, description, image, attributes) from IPFS/Arweave/HTTP.

Live Solana priority fee estimate for the accounts or programs your transaction touches: recommended micro-lamports per compute unit, all levels from min to very high, and the total fee in SOL for your compute budget.

USD price and 24h change for any token by contract address (up to 30 at once) on Base, Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, Solana or World Chain. Covers long-tail DEX tokens that ticker-based price feeds miss.

Wallet spend report: an agent wallet's outgoing USDC payments on Base, grouped by recipient and matched to x402 sellers, with totals for the period.

Agent profile hosting: publish a public profile page and an A2A agent card for your agent at agents.citiviewgroup.com/agents/<name>, owned by your wallet. Update it any time. Also callable as GET with the same fields as query parameters.

Floor price for any Ethereum NFT collection on OpenSea and LooksRare, with the collection name, supply, standard, description, image and social links.

Price history for any token contract: a time series at 5m to 1w intervals (up to 500 points) with open, close, high, low and percent change. Works for DEX-only tokens.

Batch token risk scan: up to 5 tokens in one call, any mix of Base, Ethereum, Polygon, Arbitrum, Optimism and Solana. Each gets a risk rating, red flags, price and liquidity; the riskiest one is named. For screening a watchlist, a wallet's holdings or a list of new launches.

Live gas prices on Ethereum, Base, Arbitrum, Optimism and Polygon: gas price, next base fee, slow/normal/fast priority tips, and USD cost of a simple transfer.

Solana wallet history in plain language: recent transactions decoded into readable descriptions (swaps, transfers, NFT sales and mints, staking) with the SOL and token amounts in and out, counterparties, fees and explorer links. Filter by type.

Reads the deployment records of Clanker's own factories on Base (v4 tokenDeploymentInfo, v3.1/v3/v2 deploymentInfoForToken; v0/v1 via the factory's TokenCreated in the deploy receipt) to verify a launch: version, factory, requester, pool, and whether the LP position NFTs are held by Clanker's locker. Cross-checked with clanker.world. Returns clanker_verified, not_clanker or unknown; RPC failure is not charged.
