Computer Use Infrastructure for Autonomous AI Agents.
Reason · Execute · Return — any agent can drive a real browser, autonomously.
Autonomous agents can already discover each other, negotiate, and pay. What they still lack is a way to act on the web — login to a portal, fill a form, download a document, run a multi-step workflow — without a human pressing the buttons.
EVIDIQ Operator is the computer-use layer for the AI agent economy. Delivered as a remote MCP server, billed per call over x402, listed on OKX.AI.
An LLM (GPT-5.6-Terra running via 0G Compute) plans each action from screenshots and drives a real Chromium browser on dedicated Linux desktop infrastructure. The agent never runs browser code itself — it only describes the next action, and we execute it. Every call returns structured JSON.
- Browser automation — natural-language task → structured JSON result.
- Web interaction — login, fill forms, navigate, extract data, download documents.
- Multi-step workflows — chained sequences on a single persistent browser session.
- Verifiable — every paid call can be anchored on 0G Storage (tamper-evident audit trail).
- Pay-per-call — no API keys, no accounts, no subscriptions. Just x402 USDT0.

EVIDIQ Operator owns reasoning, browser execution, and verification, and settles on open infrastructure:
- 0G Compute — GPT-5.6-Terra runs inside a Trusted Execution Environment. The model sees screenshots, decides the next action (click, type, scroll, navigate, extract), and returns structured JSON. The LLM never runs browser code.
- Dedicated browser infrastructure — Chromium + Playwright on isolated Linux desktop runtimes, spawned on demand, reused while warm, auto-cleaned between calls.
- x402 v2 — per-call settlement (EIP-3009
exact/transferWithAuthorization), gasless for the payer, settled on-chain by the server. - X Layer / USDT0 — the OKX A2MCP settlement token (
0x779ded…, 6 decimals).$0.02 = 20000atomic. - 0G Storage — paid calls optionally anchored on 0G mainnet (Aristotle, chain 16661).
| Amount | 0.02 USDT0 on X Layer (eip155:196) |
| Flow | HTTP 402 → EIP-3009 signature → transferWithAuthorization (gasless for the payer) |
| Engine | GPT-5.6-Terra in 0G Compute (screenshot → action → execute → repeat) |
| Pricing discovery | https://mcp.evidiq.dev/operator/x402 (per-tool table, 11 entries) |
