Python SDK for x402mail - send and receive email with USDC micropayments

Enables agent frameworks to query live protocol state and build unsigned BNB Chain transactions for minting, hatching, feeding, evolving, listing, buying, and claiming without writing RPC code or handling private keys.

Drop-in x402 payment middleware for MCP servers. Charge AI agents per tool call using USDC on Base chain — Python and JavaScript SDKs, no payment processor, no KYC.

Enables local AI clients such as Claude Code and Cursor to search, analyze, and monitor prediction-market data, and, once live mode is explicitly switched on, sign and submit CLOB orders from the operator's own wallet. It runs in a safe preview mode by default, writing simulated trades to local SQLite instead of sending orders.

Enables AI agents to pay per tool call in USDC via the x402 micropayment protocol, with no API keys or subscriptions required.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the user's wallet signature and track the transfer. Fees come out of the amount, and nothing moves without the user's signature. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.

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

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.

Gives MCP-compatible LLM agents direct access to real-time MEV and DeFi data via Valorem's x402-paid API endpoints, with payments in USDC on Base mainnet.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Enables cross-chain swap execution across 12 venues and 17 chains, including native Bitcoin as source or destination, with tools for quoting, execution, status, and health checks. No signup, API key, or protocol fee required.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.

Enables AI agents to look up XRPL domain availability, pricing, profiles, portfolios, and transaction status, and to get registration links for signing in the user's own wallet.

Enables an AI agent to check whether contracts are covered by ERC-7730 descriptors, preview how transactions and typed-data signatures would appear to a person, and simulate execution outcomes before signing, without holding keys or submitting transactions.

Enables AI agents to interact with a Liquid network wallet, including balance checks, transaction history, and sending L-BTC or Liquid assets. Backed by an in-process LWK wallet, requiring only a mnemonic, with both stdio and HTTP support.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Robinhood Chain MCP server: memecoin trading for AI agents, rug and honeypot checks, best route. Enables AI agents to discover screened new Robinhood Chain tokens, quote swaps across multiple routers, and prepare buy or sell transactions for wallet signing without holding funds or keys.

A read-only MCP server for safely exploring Nostr, enabling agents to resolve identifiers, fetch profiles and events, query notes, and inspect relay metadata. It does not accept private keys or publish events.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

PayQL is an MCP server that lets any AI agent query The Graph and pay per query in USDC — gasless, keyless, bring-your-own-wallet.

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

A self-hosted decision engine that sits between an AI agent and blockchain execution. Agents submit a proposed action, Guardian returns an explainable ALLOW / WARN / BLOCK before anything gets signed or broadcast.

DoI oracle for Nostr pubkeys: scores social, vouch, access, and economic-stake dimensions. Returns schnorr-signed cert with per-dim samples. L402-priced at 2 sats. Drop-in for agents needing Sybil resistance.

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it

A MCP server that provides NOSTR protocol tools for LLM agents, enabling signing, publishing, querying, and encrypted DMs with a defense-in-depth safety stack.

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

Provides access to 70 paid APIs as MCP tools with per-call and session budgets, paying via x402/USDC on Base without requiring an account or login. Includes a built-in allowlist of hosts and safe defaults to prevent unintended payments.

Gives MCP clients read-only Ethereum mainnet tools for tokenized stock prices versus listed share prices, live Uniswap V3 swap quotes against USDC, public wallet portfolios, Hyperliquid accounts, the Traivo AI scorecard, gas data, and position sizing. It never signs or sends transactions, instead returning a prefilled trade link for the user to review and sign in their own wallet.
