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.
Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.

Patchwire is a free, read-only MCP server for security advisories on modern JS, AI and web3 stacks. It reads maintainers' own advisories and vendor security posts every hour, often days before they reach the GitHub Advisory Database, and returns vulnerable ranges, fixed versions per release line and the conditions that make each flaw exploitable. Send package names, never versions. No account, no key.

Encrypted memory, knowledge graph and provable history for AI agents. ENYAL is the trust infrastructure for autonomous AI: identity, encrypted memory, and BSV-anchored proofs.
