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.
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.
Skavio LLC provides 18 hosted MCP tools for native Circle USDC payments via x402 v2 on Base and Solana: transaction verification, recipient/amount matching, blockchain evidence PDFs, DNS/TLS audits and agent utilities. Discovery and status tools are free; paid MCP calls require explicit buyer wallet authorization. The separate standalone Base-only HTTP APIs include USDC Verify (0.02), Match (0.03), Evidence PDF (0.05), and four DeepSeek-only web operations: Fetch (0.01), Search (0.02), Extract (0.02), Extract + Analyze (0.03 USDC). Those HTTP routes are not additional MCP tools. Evidence PDFs are not tax invoices.

Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.
Timestamped proof that AI outputs and data existed, anchored on the Privi blockchain.
Block an action that a signed mandate does not permit, at the moment the action happens. Checks amount, payee, audience, currency, window and intent in fixed order; 100 checks a day free, then 0.005 USDC per call over x402 on Base mainnet.
