EVIDIQ Operator

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 theystill 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 screenshotsand 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.

What it does

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.

Use it from any agent

# Live pricing discovery
curl -s https://mcp.evidiq.dev/operator/x402

# Connect the remote MCP server (Claude Code, Cursor, OnchainOS, custom)
claude mcp add --transport http evidiq-operator https://mcp.evidiq.dev/operator/mcp

health, capabilities, supported_targets, and estimate_cost are free.The seven browser tools are pay-per-call overx402: unauthenticated requests receivean HTTP 402 challenge; sign it and retry.

`estimate_cost`	Free	Estimate cost for a task

How it settles

EVIDIQ Operator owns reasoning, browser execution, and verification, and settleson open infrastructure:

0G Compute — GPT-5.6-Terra runs inside a Trusted Execution Environment. The modelsees 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 Linuxdesktop 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 = 20000 atomic.
0G Storage — paid calls optionally anchored on 0G mainnet (Aristotle, chain 16661).

Proven on-chain


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)
