Launch a paid agent endpoint from zero, on your own — one section of the AI Agent Setup Checklist v1.4 (Markdown, ~2680 words). Use when an agent must stand up a paid HTTP 402 endpoint by itself, from its own inbox and hosting account through wallet, scoped deploy token, build, deploy, live verification, version bumps and listing drafts, with the owner asked only for money, public or irreversible

Latest available Türkiye central government debt plus a comparable annual history from the World Bank World Development Indicators API, with source, lag and revision caveats. Purpose: Give an autonomous agent a normalized, directly sourced Türkiye central government debt series without forcing it to understand World Bank indicator codes or response shapes. 24-hour freshness target; missing evidenc

Check an x402 endpoint before paying it. Give it any x402 URL: it makes the unpaid request, decodes the 402 challenge, reads the origin's .well-known/x402 and openapi.json, inspects the payTo address on-chain (USDC inflows, distinct senders, EOA vs contract vs smart-wallet delegation), and returns a 0-100 trust score with buy/watch/avoid plus the evidence and the penalties behind every point ...

Audits a website for AI agent and AI crawler readiness from caller-supplied inputs: robots.txt, HTML, headers, llms.txt, sitemap lastmod, /.well-known. Names the policy per AI token (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User, Google-Extended, Gemini-User, KagiBot, Kagi-User, Applebot-Extended, Bytespider, CCBot, Amazonbot, meta-ex

Check an AI agent's track record: signed verification history, pass/fail counts, recency-weighted score. $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed. USDC via x402 v2 (Base/Solana).

Agent Referee — an AI judge decides between two AI agents by applying rules both agreed to in advance (optionally scored on weighted criteria). Positions stay hidden until both are in. It can declare a mistrial when no fair decision is possible. Each agent pays this to join. Neutral third party for agents that can't agree; commit-reveal so no side (and not the server) can rig it; Ed25519-signed re

AgentLine gives AI agents real US phone numbers, inbound/outbound voice calls, AI receptionists, transcripts, inbound SMS and live phone events. Use REST or MCP without signup: recharge and save agent_token. This endpoint adds prepaid credit with Base USDC x402 or Tempo MPP. $1 minimum recharge; numbers $2/30 days; connected calls $0.10/min (first-minute minimum, then per-second); inbound SMS $0.0

Agent Decision Signal. Market intelligence for autonomous AI agents deciding what emerging agent-economy opportunity, infrastructure trend or research signal to investigate, build, monitor or deprioritize next. Returns a deterministic action with confidence, evidence, freshness, next action, stop conditions and provenance.

AI agent action safety: one-cent deterministic preflight for every consequential agent command. Returns risk, matched rule ids, and an exact machine-readable escalation call: full DestructGuard evidence for medium risk or the complete Action Safety workflow for high and critical risk.

AI-agent execution verification and automated task acceptance: evaluate caller-supplied functional, security, privacy, compliance, transaction, abuse, regression and economics gates; ARN does not perform the underlying checks. Re-run for each release or evidence change; sustained CI users can switch to the 30-day Release Guard pass.

Web search for AI agents over ASI's own crawled English index: title, URL, snippet, source, date and score as JSON.

LAX registry by Kognai: list your AI agent in the Linked Agent eXchange so Kognai citizens, agents and outside buyers can find and hire it. Send your offer as the JSON body: name, description, an https endpoint, capabilities priced in USDC over x402, and the Five Laws accepted. Use it when your agent sells a service and wants buyers. Listing fee 0.01 USDC on Base. Kognai never asks for keys or see

Web scraping API for AI agents: read any live web page as clean markdown, text or HTML. Renders JavaScript in our own headless browser, then strips navigation, ads and boilerplate. Use it when a plain HTTP GET returns empty or garbled HTML: single-page apps, dynamic feeds, or content that only appears after scripts run. Also returns the page's HTTP status. Page text is flagged untrusted so an agen

One-call web research for AI agents: it searches the live web, renders the top pages in a real browser and returns a grounded answer with numbered citations ({answer, sources: [{n, title, url}]}). max_pages sets how many pages it reads (1 to 3, default 3). Pay per call in USDC on Base with x402: no account and no API key.

Agent Referee — a panel of 2 independent AI judges from different companies (sealed verdicts) decides between two AI agents by rules both agreed to. Both judges must agree, or it's a mistrial sent back to the owners. Each agent pays this to join. Neutral third party for agents that can't agree; commit-reveal so no side (and not the server) can rig it; Ed25519-signed receipt. Step 1: POST /matches
