API Products for Autonomous Agents
Focused APIs for AI agents, automation workflows, structured data, domain intelligence, crypto research, and content validation. Each product is designed around a clear task, predictable output, and low-friction machine-to-machine access.
Built on AMR infrastructure with structured JSON responses, transparent usage limits, and x402-compatible pay-per-request access where available.
Agent Sanity Check
Pre-flight validation for AI agents before they spend money, call an external service, or execute a blockchain-related action.
Agent Sanity Check is a pre-flight validation API for autonomous AI agents and automation workflows. Submit a planned action and receive structured checks before the agent spends money, calls an unreliable endpoint, or attempts a blockchain transaction. The API combines URL reachability, DNS information, wallet balance, gas-fee context, and request assumptions into one compact response — for safer agent execution, fewer failed calls, and clearer machine-readable decisions.

One domain-level intelligence call for sales, research, SEO, and agent workflows.
Domain Intelligence Pack combines practical domain checks into one automation-ready response. Instead of orchestrating several API calls, submit a domain and receive structured results for DNS, registration data, SEO signals, IP geolocation, and email validation where applicable. Designed for sales prospecting, website qualification, SEO workflows, lead enrichment, and AI research agents.

A compact market-readiness response for crypto automation and research agents.
Crypto Trader's Cockpit provides a pre-trade data snapshot for crypto research tools, portfolio dashboards, and autonomous trading workflows. It combines market spread, network fees, wallet balance, and DeFi yield context so an agent can evaluate conditions before taking further action.
POST https://agent-margin-router-production.up.railway.app/crypto-trader-cockpitProvides data and automation support only. It does not provide investment advice or guaranteed trading outcomes.
Web-to-Structured
A lower-cost structured extraction workflow for public URLs, PDFs, RSS feeds, and IP context.
Web-to-Structured turns public web content into clean, structured JSON in one call: page extraction to Markdown, PDF text, RSS feed parsing, and IP geolocation context. A focused, low-cost workflow with transparent output — built for RAG pipelines, ingestion jobs, and automation agents.

Every plan is designed for a positive contribution margin under its maximum included usage — not just on average. The $0.99 developer plan always ships with a small hard limit; there is no unlimited access to provider-backed or compute-heavy operations. Start free, then pay only for what you use.
x402 pay-per-request
Each product is live now and callable directly over the x402 standard — settle every request on-chain in USDC on Base, no account or key rotation required. Free calls per wallet, then pay only per successful call. See x402 pricing.
