Sentinel is a runtime enforcement layer for agent payments that blocks fraudulent transactions by enforcing signed mandates, tracing provenance, and detecting prompt injections. It acts as a guard between the agent and payment rails to prevent unauthorized payments.
Enables checking liquidity depth for Solana DEX pools (Raydium, Orca, Meteora) via pay-per-call x402 micropayments. Returns TVL, slippage estimates, volume, and fee tier for a given token mint.
Wallet-funded remote MCP for live Solana priority fees, transaction simulation and diagnosis, token-risk checks, PDF-to-Markdown, and audio normalization. Paid tools use x402 on Solana and Base with no API key.
Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.
Enables AI agents to manage USDC wallets on Solana, allowing them to send payments, create invoices, and access paid APIs within human-defined spending limits. It uses threshold signatures to provide agents with financial autonomy while ensuring secure oversight and transaction approval.
MCP server for paid business data services with free previews and paid tools (enriched search and competitive analysis) using x402 payment flow via Pyrimid Protocol on Base.
agenticpay lets MCP server developers monetize tools via per-call USDC micropayments on Solana, using the x402 protocol. Each tool declares a price; agents pay via signed Solana transactions; settlement happens on-chain in ~1.5–2 seconds.
Enables AI agents to make micropayments using USDC on Solana via the x402 protocol, supporting payment requests, on-chain verification, and revenue tracking.
A budget-bound x402 payment wallet for AI agents: it autonomously pays HTTP 402 payment-gated URLs across every major chain (EVM, Solana, and many non-EVM families). Self-custodial and backendless, your key, your RPC, with spend caps enforced before any on-chain send.
Ag402 is the payment layer for Coinbase's x402 protocol. Wrap any API or MCP server with a paywall in one command (ag402 serve), or let your AI agent auto-pay for paid APIs (ag402 run). Zero code changes for both buyers and sellers. Solana USDC, ~0.5s settlement, non-custodial, 648+ tests, MIT licensed. Works with Claude Code, Cursor, OpenClaw, LangChain, AutoGen, CrewAI out of the box.
