360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Check any x402 endpoint before your AI agent pays it: trust grade, verdict, and hijack checks.
Non-custodial limit, stop-loss and DCA trading on Epsilon (Robinhood Chain) for AI agents
Agent-native XRPL infrastructure: 19 paid MCP tools, x402 USDC on Base, non-custodial XRPL actions.
Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
Remote MCP server for crypto trading signals and the public ledger that scores them, losses included. Read tools: open signals, the signal ledger (matured wins and losses), signals cancelled by the BTC regime veto with the outcome they would have had, market snapshot and ticker for scanned Binance symbols, the scheduled BTC chart read, and news headlines. The public read tools work without a key. With a free API key from ribqa.com: your own bots and strategies, and rate-limited strategy backtests. No tool places, simulates or cancels an order. Free during beta.
Agent tools marketplace: Wallet audits, Notes, ETH + Base JSON-RPC. USDC on Base, no account.
Durable identity and memory for AI agents, anchored on the Emercoin blockchain.
