Archal

What is Archal

Archal provides stateful API sandboxes for testing AI agents and integrations. Each sandbox contains one or more stateful environments that behave like the APIs you use in production, such as GitHub, Slack, Stripe, and more. You can test API integrations without test accounts, rate limits, or dirty state. Environments are independently built simulations of the services they represent, not the providers' live services.

How to use Archal

1. Create a sandbox: Choose one or more environments and a known starting state.
2. Receive endpoints: Get isolated REST and MCP endpoints as each environment starts.
3. Call APIs: Use familiar API paths, payloads, and tools.
4. Inspect: See requests, responses, mutations, timing, and usage together.
5. Reset: Restore every environment in the sandbox to its declared baseline.

Alternatively, let your coding agent set you up:

• Paste the provided skill into Claude Code, Codex, Cursor, or Devin.
• The agent detects your tool, runs a command to install five verified skills, and checks access to every environment.
• You create or approve your account in the browser when prompted.

Features of Archal

• Stateful environments: Each environment retains mutations for the life of the sandbox and can reset to a declared starting state.
• Multiple environments per sandbox: Choose every environment your workflow needs; each gets its own endpoint and readiness state.
• Unified API: One Archal API key creates and manages every sandbox and environment. Calls share one gateway while each environment keeps familiar paths, methods, payloads, and response shapes.
• REST and MCP support: Environments expose REST or MCP interfaces.
• Isolation: Environment traffic is routed to Archal-managed implementations, not your production accounts.
• Inspection: See requests, responses, mutations, timing, and usage together.
• Reset capability: Restore every environment to its declared baseline.
• Environment catalog: Includes GitHub, Linear, Slack, Supabase, Apify, Cal.com, ClickUp, Customer.io, and more.

Use Cases of Archal

• Harness testing: Give every test run an isolated sandbox. Changes persist across tool calls, then reset to the same baseline.
• Integration testing: Give every branch or CI job its own sandbox without shared test accounts, rate limits, or dirty state.
• Agent training and RL: Give every rollout a sandbox with the same starting state while changes persist through the episode.

Pricing

• Free credits: $20 in usage credits included. No card required. $5 arrives upon sign up and the remaining $15 when your first sandbox is ready.
• Environment cost: Each environment costs $0.10 per minute.

FAQ

What is a testing sandbox?
An Archal sandbox is an isolated, time-bounded runtime containing one or more stateful environments. Each environment exposes familiar REST or MCP interfaces, retains mutations for the life of the sandbox, and can return to its declared starting state.

Do I need a different API for every environment?
No. One Archal API key creates and manages every sandbox and environment. Calls share one gateway while each environment keeps the familiar paths, methods, payloads, and response shapes your existing code expects.

How stateful are the environments?
State behavior varies by environment and operation. Available environments have a supported capability profile; environments in progress remain callable only where their documented behavior permits it. We do not claim complete upstream coverage without measured, dated evidence.

Can one sandbox contain multiple environments?
Yes. Choose every environment your workflow needs when you create the sandbox. Each environment receives its own endpoint and readiness state. Each environment costs $0.10 per minute.

Does traffic ever reach the real provider?
Environment traffic is routed to Archal-managed implementations, not your production accounts. Each environment profile documents any exceptional dependency or behavior before you use it.

How does billing work?
Billing is based on environment usage at $0.10 per minute per environment. Free credits are provided as described above.
