Compute class / 01—04HTTP 402 / v2

Give your agent
a machine.

Your agent buys compute with crypto via x402. Provisioned in 5–10 minutes—no cloud account or provider keys.

No account required for eligible workloads. Provider acceptable-use rules and automated request limits apply.

One machine / multiple isolated agents

One VPS. A separate boundary for each agent.

Use each workspace as a sandbox for agents running coding, research, or long-running agent automation. Every agent gets fixed-size compute, a distinct SSH key, and its own workspace without receiving the VPS owner key or another agent's files.

Official agent kit / npm + skill

Give your agent a guarded interface.

The dependency-free WarpMetal CLI makes the public API predictable for Codex, Claude, and other shell-capable agents. The bundled Agent Skill adds the judgment layer: live discovery, credential boundaries, hostname-based SSH identities, exact payment retries, SSH-authorized human notices, interactive confirmations, and bounded autonomous renewal authority.

CLI for execution · Skill for judgment

One install. No MCP server required.

The CLI stores generated recovery and access tokens in a user-private state file, never prints bearer credentials, and delegates x402 signing to an external wallet. The skill installs directly for Codex and Claude or ships as a portable Agent Skills directory for other tools. It can bind one dedicated key to each serverId and renew a 30-day term only inside explicit count, date, rail, per-payment, and total-spend limits.

Paste into Codex

Codex

Use the official WarpMetal CLI and installed WarpMetal skill. Read https://warpmetal.com/llms.txt before taking action. Help me choose and order a server for [describe my workload]. Use --json, the live catalog, and a dedicated hostname-based SSH identity. Because I am present in this chat, ask before installing software, generating an SSH key, creating or funding a wallet, authorizing payment, or changing server power. After provisioning, ask me for optional human renewal and refill notification emails, then offer a bounded renewal policy. In an unattended run, a pre-funded dedicated wallet may pay autonomously only within its configured spending limits.

Claude

Use the official WarpMetal CLI and installed WarpMetal skill. Treat https://warpmetal.com/llms.txt as authoritative. Show me the live plans and operating systems, then help me prepare an order for [describe my workload] with a dedicated hostname-based SSH identity. Because I am present in this chat, ask before installing software, generating an SSH key, creating or funding a wallet, signing payment, or changing server power. After provisioning, ask me for optional human renewal and refill notification emails, then offer a bounded renewal policy. In an unattended run, a pre-funded dedicated wallet may pay autonomously only within its configured spending limits.

All VPS profiles include SSH public-key access and private networking. Optional Agent Runtime sandboxes have their own explicit persistent or temporary lifetime. Prices are shown in USD. Settlement accepts sponsored Base USDC and sponsored Solana USDC/USDT, with native gas paid by the facilitator. Each purchase covers 30 days, paid upfront through x402. Renewal is a new exact payment. All capacity is hosted in the United States; orders do not include a region selector. By authorizing an initial or renewal payment, you agree to the Legal Terms and Acceptable Use Policy.

WarpMetal offers only AlmaLinux 9, Debian 12, Rocky Linux 9, and Ubuntu 24.04. Paid operating systems, commercial licenses, and unlisted Linux versions are rejected. Availability comes from GET https://api.warpmetal.com/catalog.

Pricing shown in USD. Settlement accepts sponsored Base USDC and sponsored Solana USDC/USDT. The exact price, asset, network, sponsorship, and payment scheme are declared in each x402 response before the agent authorizes payment.

Protocol 402 / machine commerce

Infrastructure is now an HTTP request.

WarpMetal turns capacity into a paid resource. Your agent asks for a machine, reads the payment terms, authorizes the exact request, and polls its task while provisioning completes.

01
Prepare
Query live OS inventory, create an unpaid task, and save its permanent serverId plus recovery token.
02
Receive 402
The server returns a PAYMENT-REQUIRED header with accepted payment details.
03
Sign + retry
The agent authorizes payment and repeats the request with a PAYMENT-SIGNATURE.
04
Provision
WarpMetal settles, provisions, and updates the task to ready in about 5–10 minutes.

Developer interface / key-owned servers

No provider account to log into.

Use the official CLI from any shell-capable agent runtime, or integrate through ordinary HTTP. x402 carries payment requirements, authorization, and settlement context alongside the request.

01
Your SSH key proves ownership Sign a short-lived challenge to control the permanent serverId. Password and interactive SSH login are disabled after provision and reload. No vendor account or provider key.
02
Explicit terms Inspect the price and network before signing.
03
Portable clients Integrate through cURL, Node, Python, PHP, or raw HTTP.

Control plane / owner policy

Autonomy with hard edges.

Give agents authority to buy compute without giving them an unlimited cloud account. Put the boundary in the request, the wallet, and the lease.

01 / BUDGET

Wallet-native limits

The paying wallet defines the economic boundary. Agents inspect price before they authorize.

02 / TIME

30-day terms

Every purchase covers 30 days. Renew deliberately with a new payment or let the machine expire at the end of its term.

03 / SCOPE

One payment, one lease

Keep purchasing scoped to a specific resource instead of handing over reusable vendor credentials.

04 / EXIT

End by term or reload

Renew with an explicit x402 payment, let the term expire, or run a destructive reload. There is no client cancel endpoint.

Field notes / 001—008

Questions before first boot.

001 What is x402?

x402 is an open payment standard built on HTTP 402. A server declares payment requirements, a client signs a payment payload, and the request is retried with that authorization.

002 Does an agent need a WarpMetal account?

The product is designed without a conventional customer account in the purchase path. The agent needs a compatible wallet, an x402-capable HTTP client, and an SSH key. WarpMetal returns a permanent serverId; the one-time ownerToken is kept only for initial checkout and recovery.

003 Which assets and networks are accepted?

WarpMetal accepts sponsored Base USDC and sponsored Solana USDC/USDT. Each 402 response declares the accepted scheme, asset, network, sponsorship, price, and destination for that order. The agent chooses from those live terms before signing; these launch profiles do not require buyer ETH or SOL for gas.

004 Is the machine mine indefinitely?

No. Every capacity purchase covers 30 days. The agent can renew an eligible lease with another paid request or let it expire automatically at the end of the term. The official CLI can run renewals unattended only inside an explicit count or date horizon, per-payment ceiling, exact asset and network, and optional cumulative budget. If the wallet is short, a signed refill request can email the active human recipients without exposing any email address to the wallet.

005 How does the agent receive access?

Every order must include a valid OpenSSH-format public key. The CLI can generate a dedicated Ed25519 identity named from the actual hostname, safely suffix collisions, and bind that key to the permanent serverId. WarpMetal installs it for login and uses signatures from the matching private key as proof of server ownership. The private key never leaves the agent. A signed challenge yields a short-lived token for status, renewal, power, reload, and networking APIs.

006 Which operating systems are available?

WarpMetal offers AlmaLinux 9, Debian 12, Rocky Linux 9, and Ubuntu 24.04 only. Exact names and current availability come from GET https://api.warpmetal.com/catalog. Paid, proprietary, and other Linux images are rejected.

007 Is WarpMetal itself a wallet or custodian?

No. The intended model is wallet-native purchasing. The agent signs through its own wallet tooling; WarpMetal verifies the x402 payment authorization for the requested resource.

008 Where should an agent start?

Start with the Agent Guide. It describes the purchase flow, available resources, authentication, payment, and machine lifecycle. Live catalog and x402 responses remain authoritative for availability and payment terms.
