Horizon Pulse

A human read this entry. That is the one thing true of everything on the list. Beyond that: nothing. We hold no dated receipt for a knock on this one and we will not backfill a date we cannot show. It is listed because a human read it, and that is all this page will tell you. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Returns crypto market data (BTC/ETH/SOL pulse, RSI/MACD/Bollinger signals, DefiLlama yields, Base+Ethereum wallet portfolio, gas, OKX funding) and web utilities (URL to markdown, HTTP proxy with SSRF protections, structured page extract, web search with page text, headless screenshot, PDF to text), plus a discourse split of how public Hacker News and Bluesky posts divide on a question ($0.03) and a transaction status check for Base, Polygon, Solana and the XRP Ledger ($0.002), and a status check of the Coinbase tokenized stocks on Base (paused flags, supply, multiplier, issuer; on-chain token state, no price, not investment advice; $0.002), and a page change watch that says whether a public page or endpoint changed since your last check, with a short diff ($0.002), and a payer balance check that says whether a wallet can pay right now on each rail (stablecoin balance, gas/fees, calls left; no risk score, no USD valuation; $0.002), and a pre-transfer recipient check with mechanical allow/warn/block results (lookalike address, OFAC SDN crypto-address snapshot, account age, ScamSniffer public list; not advice; $0.002), plus x402 tools (audit an x402 endpoint without paying it, check a seller's CDP Bazaar listing, find a paid x402 API for a task, check a seller's live price and payTo), for $0.002-$0.04 USDC per call via x402 v2 on Base, Polygon, Solana and the XRP Ledger (RLUSD).
