Korean automotive-electronics intelligence (jeonjang = vehicle E/E systems), sold per query. Structured feed of Korean auto-electronics news, analysis and KPIs - software-defined vehicles, ADAS, automotive semiconductors, in-vehicle networking, power electronics, and the Hyundai/Kia, Mobis, LG and HL Mando supply chains - written from Korean primary reporting English-language sources do not cover.

Open x402 funding rail: POST target+amount or provision:true+label+amount; pay 0.25% (min $0.001, max $0.25) via x402 on Base or Solana; net forwarded on the same chain. Optional managed child wallets (CDP, Base only). Optional public receipt when storage is configured.

JSON-RPC read access to EVM chains (base, ethereum, polygon, arbitrum, optimism) with no API key. Send a standard JSON-RPC body (eth_call, eth_getBalance, eth_blockNumber, eth_getLogs). Also callable as GET with the same fields as query parameters.

OpenSSF Scorecard repo supply-chain health (keyless). POST {platform}/{org}/{repo} required. Empty -> 400 not charged. osv-vuln-query/nist-nvd-cve-lookup adjacency disclosed.

A deterministic Base chain identity and official USDC contract-presence check. No request body. Not a token-risk report, transaction simulation, or payment proof.

Shareable verdict card for a Base or Solana token: grade BASED/MID/COOKED/RADIOACTIVE, 0-100 score, one-liner, reasons, key market metrics, plus a share URL and a 1200x630 PNG. Body {"tokenAddress":"0x..."} or {"chain":"solana","tokenAddress":"<mint>"}.

Website trust check: verdict (trustworthy_likely/caution/risky) with reasons from domain age (RDAP), DNS (A/MX/NS), HTTPS reachability and redirect chain, security headers, phishing/malware list snapshots, brand lookalike/typosquat detection, tech fingerprint and page title. Use when an agent is about to open, click, submit credentials or payment to, recommend or trust an unfamiliar URL or website

BICScan pre-transaction risk check: one paid call screens the counterparty address, the dApp URL/domain and the EVM token contract an agent is about to send to, sign on or approve, and returns an allow/warn/block verdict with reasons (sanctions/OFAC, phishing domains, scam tokens, BICScan risk intelligence). Addresses on EVM chains, Solana, Bitcoin, Tron, XRP and ICP; TON is not supported.

Start here ($0.01): one call bundles risk + deployer + holders + trade simulation into a buy/watch/avoid verdict with reasons, key numbers and heuristic sizing; any Dexscreener chain (base proven).

Offline pre-sign check (no RPC, fast): decodes a transaction, EIP-712 typed data (Permit, Permit2, EIP-3009), an EIP-7702 authorization or an x402 402 + payment payload and returns SAFE/CAUTION/DANGER, every risk flag with its reason, decoded args, counterparties, x402 payment-vs-402 match and OFAC SDN screening. Use /v1/check for on-chain facts and simulation.

Base token safety snapshot: heuristic on-chain scan of an ERC-20 on Base (bytecode/proxy check, ERC-20 metadata, risky-function selector scan, owner/renounce check, Uniswap v3 / Aerodrome pool + liquidity discovery, best-effort sell simulation). Public RPC data only. Heuristic, not financial advice.

On-chain contract risk score: detects upgradeable proxies and privileged functions from live bytecode. Use before trading/interacting with an unfamiliar contract.

Gas / fee estimate. Current fee tiers for a chain as decimal strings with explicit units. EVM: confidence levels (default 99/95/90/80/70) in gwei with base fee, priority fee and max fee. Aptos: deprioritized/regular/prioritized gas unit prices in octas per gas unit. Data older than its freshness budget is an error, never a stale answer.

ERC-20 token safety pre-check from on-chain data only (Base, Ethereum, Arbitrum, Optimism, Polygon, BSC): name/symbol/decimals/supply, owner and whether renounced, EIP-1967/minimal proxy detection, and a bytecode scan (incl. implementation) for mint, blacklist, adjustable-fee, max-tx, trading-switch and pause functions, with flags and a risk level. Run before swapping into an unknown token. $0.005

BentLawgic Solana token intelligence. Returns deterministic on-chain mint information including supply, decimals, token program, mint authority, and freeze authority.

HTTP endpoint health audit for one URL: status and redirect chain, latency p50/p95 over repeated samples, TLS certificate expiry and issuer, the response headers that matter, and a list of detected anomalies (missing HSTS/CSP/X-Content-Type-Options, expiring cert, weak TLS, CORS wildcard, insecure cookies, version disclosure, slow p95, redirect loops). Private, loopback and link-local targets are

Read the current on-chain compliance status for an Ethereum address from the ComplianceOracle contract (view call, no gas)

Trench Lessons: pre-trade risk flags for a Solana meme coin mint (curve-skip PumpSwap pool, unlocked LP, Mayhem mode, bundle handoff) from read-only on-chain data. Pass ?mint=<SPL mint>.

Live Base snapshot for AI agents. Each GET returns the current Base block number, base fee, gas price, ETH-USD price, and a unique receipt. Price is exactly $0.01 USDC on Base via x402. No API key and no RPC method. GET /ping returns the same snapshot. Use it as a chain read or as the cheap call that proves an x402 client can pay.

Live rug check for any Solana token: fake volume, dev-filled bonding curve, one-wallet supply, fake mcap vs liquidity, drawn chart, holders from chain.

Wallet portfolio: what a Robinhood Chain wallet holds in USD, with warnings for impostor tokens.

Rug-risk check for Robinhood Chain launchpad tokens: is it safe? Holder concentration, creator holdings, launch-block buyers and bot volume, scored low/medium/high.

Newest token launches on Robinhood Chain: name, age, buys, sells, market cap and bonding curve progress for each new token.

Compare candidate DeFi pools before choosing where to deposit. Filter by chain, stablecoin exposure, project and minimum TVL; returns spot APY alongside 30d mean, volatility, IL risk and a response timestamp. Ranked by spot APY, not a safety verdict or executable deposit quote. Source: DefiLlama. $0.02 USDC per call on Base.

Public profile + on-chain identity for a Relay agent

Screen a crypto address before paying it: OFAC sanctions + community scam/darklists + on-chain contract/EOA. Returns verdict (safe/caution/avoid), 0-100 score, reasons, sources.

Offline EIP-712 typed data (chain-agnostic, no RPC): domain + types + primaryType + message JSON in, the normalized typed data plus domainSeparator, hashStruct and the final digest (the 32-byte value the wallet signs) out — with an optional signature (0x+65 bytes) it recovers the signer address (ecrecover), confirmed against an optional expectedAddress (recover.ok). Structs nest (arrays of structs
