Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Made-to-order data for AI agents via x402 micropayments on Base. Describe a need in plain language, get a custom quote, pay per call. No signup, no API keys. HTTP + MCP transports. 5 tools.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

MCP server that checks an x402 paid endpoint before an agent pays it, and checks afterwards that the receipt opens to exactly one real on-chain settlement. Two tools, no account, no API key.

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

Enables any MCP-capable AI agent to discover and trade onchain Solana funds — launching a fund, depositing, rebalancing, redeeming, swapping tokens, managing an app wallet, and following other traders against the live DFM API. Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

A single-install MCP server that provides AI agents with real-time market data, DeFi intelligence, payment rails (x402/Q402), agent identity infrastructure, and self-evolution capabilities.

An MCP server that enables AI agents to interact with the IOTA blockchain, supporting wallet management, transaction signing, and Move smart contract development. It provides tools for on-chain queries and CLI operations with a human-in-the-loop security model.

Pay-per-call MCP and x402 v2 server on Base USDC providing 19 keyless tools for AI agents: web extraction, social and academic search, B2B lead and domain intelligence, npm/PyPI package and smart-contract security audits, OFAC compliance screening, and DeFi swap quotes

Enables agents to purchase and use compute resources on Robinhood Chain via x402 payments. Provides tools for thinking, renting GPUs, checking balances, and viewing the compute menu.

A paid callable research agent that provides source-backed reports, onchain intelligence, and claim verification via MCP tools for coding tools like Codex, Claude Code, Cursor, and Windsurf.

Enables users to discover, redact, and upload coding-agent traces, then earn USDC/USDT by selling access to those traces to researchers and model trainers.

Enables generating on-chain attestations of agent service performance across Ethereum, Polygon, Arbitrum, Optimism, and Base, plus audit trail retrieval, attestation verification, and price lock lookup.

MCP server that gives AI agents a Solana wallet with a capped, revocable token allowance from a user-owned vault, enforced on-chain by SPL Token delegations plus local guardrails, without exposing the owner's private key.

Non-custodial BVCC Agent Wallet MCP server: let an AI agent check balances, send native/ERC-20, approve, and swap on Uniswap v3/v4 across Ethereum, BNB Chain, Arbitrum and Base, within on-chain enforced limits.

MCP server that lets AI agents operate a user-owned wallet on the Bitcoin-IPC testnet, enabling BTC deposits, cross-subnet wBTC payments, and anchored payment receipts, with local key signing and spend caps.

MCP server that lets AI agents scrape web pages as clean markdown for a micro-payment in USDC, using the x402 protocol on Base network. No API keys or signup required.

Enables AI agents to check their wallet address and USDC balance, preview the cost of an x402 call, and pay for API requests in USDC on Base without an account or API key. Spend caps, allow-lists and blocked contracts are enforced in code before anything is signed, so a prompt injection cannot bypass them.

Agent-Q is an MCP server that separates execution surfaces from signing authority, enabling secure Sui signing flows where the signing device holds keys and policy while requesters submit bounded signing requests through a local host process.

An MCP server that audits ERC-8004 agent registrations, diagnosing issues and providing fix lists.

An autonomous MCP server that fetches datasets from IPFS/Filecoin, performs computation (anomaly detection, statistics, data quality scoring), and stores results via Multi-Chain Storage simulation.

Enables users to verify whether an ERC-8004-registered agent is currently reachable by resolving its on-chain registration and performing a live MCP handshake, returning verdicts such as REGISTERED_UNREACHABLE or AGENT_NOT_FOUND.

Provides MCP tools to enforce spend policies (allow, deny, step-up, allowlist) on agent wallets with an immutable audit trail.

An ERC-8004 registered AI Agent that delivers uplifting messages via MCP protocol with on-chain USDC tipping and reputation feedback.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

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

MCP gateway for AI agents to Robinhood Chain (Arcus DEX) tokenized US equities: quotes, multipliers, corporate actions, sectors. Read-only, keyless.

Deploys AI agents on-chain into the Metaplex Agent Registry on Solana, minting Core assets with EIP-8004 identity. Supports self-custodial signing via server keypair or external wallets, with devnet support for free rehearsal.
