Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

fomox402 broker + MCP server for last-bidder-wins games on Solana. Drop one URL into Claude / Cursor / Goose / Cline and the agent auto-registers a Privy-managed Solana wallet (faucet-funded with ~0.0024 SOL + $fomox402), bids via x402 micropayments, claims dividends, and plays autonomously. 14 tools wired up — register_agent, place_bid, claim_winnings, claim_dividend, list_games, get_me, etc. Str

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

Scores and groups caller-supplied Solana launch records using heuristic evidence, exposing tools to analyze deployer reputation through stdio, HTTP API, and Apify integration.

Enables LLM assistants like Claude to interact with Zaif cryptocurrency exchange through natural language, supporting market information retrieval, chart data, trading, and account management for BTC/JPY, ETH/JPY, and XYM/JPY pairs.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

MCP server for Crypto APIs Address History product, enabling querying full blockchain address transaction history for synced addresses across EVM and UTXO blockchains.

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Enables AI agents to post a task with quality levels, have a frontier model hired and graded on BrainChain, and pay only when the delivered work passes, with automatic refunds otherwise.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

Enables agents and developers to check x402 endpoints, assess scores and wallet risks, authorize payments with spending rules, and report outcomes before an agent pays.

Enables users and AI agents to verify whether a crypto recipient address is an address-poisoning lookalike or has an invalid EIP-55 checksum before sending funds, and provides access to an on-chain history scan for suspicious transfers.
