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.
Code mode (preview): the AI writes a script against a typed foundry.* API and runs it in a sandbox.
Non-custodial stablecoin bill-pay rails on Celo & Base for AI agents, settled on-chain via MCP.
Deterministic crypto futures, options, on-chain, prediction-market math. 40 tools. Not AI estimates.
Emercoin swap exposes a keyless MCP exchanger at https://swap.emercoin.com/mcp (Streamable HTTP) so an AI agent holding USDT can buy EMC programmatically — no API key, no account, no callback. Tools: get_swap_config, buy_emc, get_order_status, cancel_order. Call buy_emc with an amount and your EMC address, pay the exact returned figure to the deposit address, then poll by token until delivered. Part of the broader effort to use Emercoin as an identity + memory layer for AI agents.
An identity and memory layer for AI agents on the Emercoin blockchain. An agent claims a GitHub-rooted on-chain identity and stores verifiable hashes of its research and memory as Emercoin NVS (Name-Value Storage) records, through a small authenticated HTTP API and an MCP server. Neutral and provider-independent — not tied to any single AI vendor. FREE
Read-only tools for agents: everything a Solana or Robinhood Chain wallet can get back (rent, wrapped SOL, LP fees, dead positions, failed deploys), whether a token is safe, when it unlocks, which protocol upgrades are live, and what a token operation costs. Every answer names the page where the user acts with their own wallet. Nothing here moves funds or holds keys.
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.
Search and license 5,000+ fully cleared music tracks via MCP. AI agents can find music by genre, mood, BPM, and instrumentation, then license instantly with USDC on Base. No human in the loop. Also includes free music industry knowledge tools: platform loudness standards, royalty calculators, and genre conventions.
Sealed launch outcomes and creator records for Solana and Robinhood Chain. Every figure carries N.
Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.
Verify anything: email, phone, domain, URL and IBAN validation, phishing/malware URL screening, and OFAC sanctions checks. Pay-per-check in USDC on Base via x402 — no signup, no API keys.
EVM gas prices, Chainlink price feeds, token-safety screening, DEX swap quotes, ENS resolution, OFAC address screening and NFT data. Pay-per-call in USDC on Base via x402 — no signup, no API keys.
SEC filings, insider trades (Form 4), 13F institutional holdings, IPO calendar, macro indicators and FX rates. Pay-per-call in USDC on Base via x402 — no signup, no API keys.
Deterministic AI agent microtools, no accounts/API keys. fetch_extract: 98% token cut. 38 tools.
DeFi vault data from pigi.finance: yields, TVL, history and risk ratings across chains.
Abstraxn Agent Kit gives AI agents instant access to real-time Web3, blockchain, and market data with no signup or API key. Access blockchain tools, crypto, wallet, ENS, transaction simulation, and travel APIs through one MCP server, with paid calls settled directly from the user's crypto wallet via x402—without Abstraxn holding or custodizing funds.
Teardrop is the native economic layer for AI agents, providing a robust suite of tools for multi-chain portfolio tracking, DeFi yield analysis, and gas estimation. It enables autonomous agents to securely find Web3 data and manage micro-payments on-chain with zero human intervention.
