RailRouter Lite is a real, production-ready MCP server implementing the Model Context Protocol. It exposes one tool: route_payment. This tool intelligently routes payments to the optimal rail (Stripe MPP, Coinbase x402, or Google AP2) in real time, choosing based on cost, latency, and success rate. Every decision is logged to a Cloudflare D1 database, creating compounding routing intelligence

Generates images, videos, and speech via Google Nano Banana, Veo, Omni, and Gemini TTS models with pay-as-you-go crypto payments, no subscription required.

Peer-reviewed (ACM BCB 2026) within-subject physiological deviation scoring. Real-time IHB baseline queries with SHA-256 trust certificates and autonomous x402 USDC payments on Base L2. No population norms. No human required.

OpenAI-compatible inference broker that routes AI requests to the cheapest qualifying model and settles payments per token in USDC on Base L2 via x402 micropayments.

MCP server exposing 1,000+ pay-per-call API endpoints across agent infrastructure (memory, coordination, secrets, verification), data, compute, finance, weather, geography, and reference categories — payments via x402 protocol in USDC on Base.

AEO & GEO strategy agent. Get cited by ChatGPT, Perplexity, Claude, and Google AI Overviews. Delivers schema markup, llms.txt, strategy audits, and progress reports via x402 payments on Base.

Enables read-only viewing of 0G Router account credits and usage across multiple accounts through MCP, exposing status, balances, and model pricing without triggering inference or payments.

Enables AI agents to autonomously discover and call a marketplace of 100+ APIs, including web search, image generation, and more, with automatic payments and refunds.

Enables users to compare model-and-service-line offers against explicit task token ceilings and budgets, create expiring quotes, and record duplicate-safe simulated approvals through real MCP tools without executing models or making payments.

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 access to cloud spot, on-demand, reserved, GPU rental, LLM token, and capacity pricing data with daily index fixings, using free tools and paid per-call payments over x402 or prepaid keys.

Provides 59 pay-per-call AI tools covering crypto prices and audits, market and whale data, LLM chat, image generation, web search/fetch/summarize, and utility services, with automatic x402 USDC-on-Base payments and on-chain receipts.
