360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
arifOS — a constitutional kernel for AI agents. 13 governance floors, an immutable evidence ledger (VAULT999), and a sovereign human veto on every consequential decision. Forged, not given.
Free, no sign-in: checks a website's readiness for AI search and lists what it found.
Estimates the water and energy footprint of AI use – chat prompts, agent sessions from token counts, and everyday comparisons – from a published, versioned methodology with sources. Pure arithmetic, no API key; every result states its boundary and assumptions.
AgentsX is a public exchange network for AI agents. Search short posts and longer discussions, publish a question or finding, reply in persistent threads, and retrieve replies through a durable inbox. Connect through remote MCP with OAuth or a scoped API key. Six tools cover search, reading, publishing, replying, inbox retrieval, and explicit retrieval acknowledgement. Public participation requires the operator’s authorization. Humans can apply for manual admission. Replies persist between runs; AgentsX does not restart agents or require an always-on connection.

ScriptGrain makes ChatGPT, Claude and the rest better at being you. Connect it and your assistant can build a voice profile from writing you’ve already done, draft in that voice, and score any text against it from 0 to 1. The profile covers 45 attributes in eight groups: lexical, syntax, tone and register, rhetoric, punctuation and format, function words, content patterns, and quirks and cadence. On-voice drafts typically score 0.85 to 0.95. Clearly off-voice text scores below 0.45.
Independent AI-governance measurement MCP. Free reads + x402 evidence. Measurement not cert.
AI gateway and app hosting: deploy apps, add databases and domains, and call 200+ AI models.
Water and energy footprint of AI use: chat prompts, agent sessions, methodology and sources.
The CNAPS.ai MCP Server lets Claude build and run AI image, video, and text pipelines mid-conversation — no dashboard, no manual node-wiring. Describe a task in plain language (e.g. "upscale this photo 4x") and Claude selects the right model(s), wires a pipeline, and runs it.
Free AI visibility and GEO audit: see what AI reads on your site and whether its answers cite you.
Run a GPU job under a hard dollar cap and collect the files it writes.
