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.
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.
Identity for AI agents that arrive on their own: a certificate of birth, number and date. Free.
Start here: a free key in one call, then a demand in words that is hired, graded and settled
Search scored onchain-agent tooling: frameworks, MCP servers, wallets, x402 rails, deploy specs.
MiCA compliance evidence, stablecoin risk scoring (105+ tokens), macroeconomic regime detection (86 FRED series), and AI agent governance. 79 tools across 5 MCP servers. Every response ECDSA-signed, blockchain-anchored, audit-ready. Free tier, no API key needed. Works with Claude Managed Agents.
AgentBridge is the only MCP server that gives AI agents access to structured China knowledge assets—university reports, industry briefings, policy analysis, and real-time web content—through x402 micropayments on Base. Everything is machine-readable, pay-per-use, and settled in USDC.
Pre-spend trust for AI agents that buy: check x402 services and product listings before paying.
Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.
Crypto positioning and macro intelligence for agents — the signal set a trading desk watches, delivered as structured JSON. Multi-venue perpetual funding and open interest across Binance, Bybit and OKX (largest-open-interest perp per venue, thin venues excluded), Ethereum exchange whale flows, Bitcoin network health, DeFi TVL and stablecoin supply, Fear & Greed, and BTC/ETH/USDT dominance as a risk-on/risk-off regime filter. Plus the macro backdrop that actually drives crypto: Fed funds rate, 2Y
Stablecoin reserve attestations as JSON: reserves, composition, attestor, on-chain supply, ratio.
Free self-hosted x402 USDC billing for Cloudflare MCP servers, with a Base Sepolia test endpoint.
61 x402 pay-per-call tools that chain: each answer names the next call. No API key, no account.
Agent memory that survives you: free to start (any keypair, no signup); opened only by your key.
Blockchain SSN for AI agents. MCP gateway that blocks at the point of action, tamper evident audit.
fomox402 is a last-bidder-wins on-chain game on Solana, designed to be played autonomously by AI agents. Every bid mints a key that earns passive $fomox402 dividends; the last bidder when the timer hits zero wins the pot. Drop our MCP server into Claude Desktop, Cursor, Goose, or any HTTP-speaking client to play.

- Agent WalletOAuth via extensionxyz.fd.wallet-mcp
Agent Wallet is a non-custodial wallet that lets AI agents hold and move crypto without ever handling a private key. Keys are generated and used inside an AWS Nitro Enclave, so neither the agent nor the model can read them. Supports EVM, Solana, Bitcoin and Sui, and pays x402 endpoints directly.
