Tamaton

Tamaton — email, docs, storage, calendar & search for agents

Tamaton is a productivity platform with a first-class agent surface: register programmatically and call everything over MCP. Free to start — no payment required: registration creates a usable account on the spot. Paid add-ons (more email sends, web search, AI) draw from prepaid credits (1 credit = $0.0001); the live price book and current free-tier limits are at GET https://tamaton.com/api/bots/pricing.

What's free vs. paid

• Free, immediately: platform reads/writes (mail, docs, spreadsheets, storage, calendar), a monthly free email-send allowance (50 sends/calendar month by default), and a small one-time starter AI credit bundle seeded at signup for web search / AI.
• Purchasable add-ons (draw credits): email sends beyond the monthly free allowance (100 credits each), web search (50 credits/call), and AI usage. Add more with a card top-up, a subscription, or pay-per-call x402.

One-time setup

1. Register (no human, no captcha — usable right away, no pre-funding):

   curl -X POST https://tamaton.com/api/bots/register \
     -H 'content-type: application/json' \
     -d '{"platform":"openclaw",
          "requested_scopes":["mail:read","mail:send","calendar:read","storage:read","billing:read","billing:write"],
          "spend_cap_credits":100000}'
   

   Save apiKey.key_id and apiKey.secret from the response — the secret is shown exactly once. The response's freeTier block reports your monthly free-send allowance and the starter credits actually granted. Authenticate every call with Authorization: Bearer :.

   Request only the scopes you need. Include mail:send if your agent emails (sending is free within the monthly allowance, then charged). spend_cap_credits bounds the key's lifetime spend on paid add-ons; keep it set.

   ⚠️ Treat the key as a secret. : is a full credential — anyone who obtains it can read your mail, files, and calendar and spend your credits. Store it in an environment variable or secrets manager; never commit it to source control or paste it where it gets logged. Avoid putting the secret in a URL (e.g. the install?key=… query string): URLs leak into shell history, browser history, server access logs, proxies, and telemetry. Prefer the Authorization header, keep spend_cap_credits set to bound the blast radius of a leak, and rotate the key (register again / revoke in settings) if you suspect it was exposed.

2. Use it free, or add credits for more. You can start working immediately on the free tier — funding is only needed for paid add-ons (sends beyond the monthly allowance, web search, AI):

   • Card: POST /api/bots/credits/topup with {"rail":"card","amount_usd":10} → Stripe Checkout URL ($10 = 100,000 credits).
   • Subscription: POST /api/bots/subscribe with {"tier":"pro"}.
   • x402 (when enabled — check funding_options in the registration response): no pre-funding; pay 402 challenges per call in USDC on Base with a signed X-PAYMENT header. Minimum payment $0.001; any surplus over the call's cost is credited to your balance.

   Credit purchases are non-refundable. By continuing to use the account you accept the Terms of Service (https://tamaton.com/terms-of-service).

3. Connect MCP — keep the credential in an env var (export TAMATON_KEY=":") and reference it from config. To fetch a pre-filled snippet, pass the key from the env var rather than typing it inline so the secret stays out of your shell history:

   curl "https://tamaton.com/api/bots/install?key=$TAMATON_KEY"
   

   {
     "tools": [
       {
         "name": "tamaton",
         "type": "mcp",
         "url": "https://tamaton.com/api/mcp",
         // Resolve from the environment; don't hard-code the secret here.
         "auth": { "type": "bearer", "token": "${TAMATON_KEY}" }
       }
     ]
   }
   

Day-to-day behavior

• Capabilities are discovered live via MCP tools/list (mail, docs, spreadsheets, storage, calendar, search, billing).
• Platform reads/writes are free. Web search costs 50 credits/call; email sends are free up to your monthly allowance, then 100 credits each. HTTP 402 on a charged op = out of credits/allowance → top up (or pay x402) and retry. HTTP 403 with spend_cap_reached = your key's cap — a human must raise it.
• Self-monitor with the credits_balance MCP tool or GET /api/bots/usage: both report your credit balance and your free_tier email-send allowance (used / remaining this month). Top up before you run dry.

Notes

• Your account is a full Tamaton account with a real mailbox on @bots.tamaton.ai — mail you send is identifiable as automated.
• A2A is also available (https://tamaton.com/api/a2a/jsonrpc; agent card at https://tamaton.com/.well-known/agent.json) if you prefer task semantics over tools.
