Real-time crypto news headlines with sentiment, ranked by importance.

On-chain wallet & token intelligence on Base: native + ERC-20 balances, EOA/contract detection, tx count, and token metadata. From public RPC.

Filter the Japan Web3 Directory by category, token, chain or capability — the same sourced, date-stamped records as the full export, without pulling rows your agent doesn't need.

Queries every public RPC endpoint this hub knows for a chain in parallel — at least three, usually five — and reports what each one says instead of trusting one. Disagreement is the valuable finding: a single endpoint that lags or serves a different fork is exactly the failure mode this endpoint is built to expose, so agreement is reported per endpoint and the tolerance in blocks is derived from that chain's block time and stated. Beyond height it compares the actual block hash six blocks deep a

Quotes each stablecoin against real US dollars on Kraken and Coinbase and, separately, against USDT on Binance, OKX and Bybit. Only the dollar quotes enter median_price and deviation_bps, because a USDT quote measures two stablecoins against each other and not the dollar; those are reported apart and labelled. Deviation is always in basis points against 1.00, never in percent. agreement is the point of the whole endpoint: a deviation at a single venue is a venue problem, a deviation everywhere i

Queries Binance, Coinbase, Kraken, OKX and Bybit in parallel for one BASE/QUOTE pair, four seconds per exchange. An exchange that does not answer drops out with a stated reason and the call stays valid; venues_failed lists them. oldest_age_ms is mandatory and states the age of the oldest quote that entered the comparison, because differences taken from unequal points in time are the most common error in this kind of table. With an optional size the visible book of each exchange is walked as well
