How it works

AI inference billed by time credits.

Buy consumable time credits for a model — purchasable in blocks of 15, 30, or 60 minutes — with Bitcoin Cash or LIFT, and use them up as you work. No per-token metering, no monthly subscription, no surprise at the end of the month.

paytaca — ai

Instead of per-token metering or a monthly subscription, you buy consumable time credits — purchasable in blocks of 15, 30, or 60 minutes — and use them up as you work.

Plans · paid in Bitcoin Cash

Prepay time credits.
Use every second.

Pick a model, buy a plan with BCH or LIFT, and the time is yours. Plans are consumable time credits — purchasable in blocks of 15, 30, or 60 minutes — not balances that stack, so while a model still has active time, buying another for it costs nothing extra.

Token billing vs time billing

Same model. Two very different bills.

token-based

A bill you meet at the end

  • Priced per token in and out
  • Every retry and long tool call adds up
  • You only know the total once it’s over
? total unknown
time-based · Paytaca

Time credits you already own

  • One price for 15, 30, or 60 minutes
  • Only real inference time is counted
  • Think, pause, and retry without the meter running
✓ total known upfront
Auto-refill

Out of time?
It buys more for you.

Arm auto-refill once and Paytaca keeps the model running. When an active plan hits zero, it quietly buys another — same model, same plan size — and only ever spends up to the budget cap you set.

  • per modelArms one model at one plan size.
  • cappedStops at the --max-minutes you set.
  • silentBuys mid-session, without a prompt.

CLI + MCP · coding agents

The same plans,
inside your agent.

paytaca-cli runs a local MCP server, so opencode, pi, and omp can read balances, watch history, and buy Paytaca AI plans. We only support agents that let you run open-source and open-weight models. The one-step installer writes the config, creates a wallet-bound API key, and offers to buy a plan when none is active.

Illustrative snippet. opencode also gets the Paytaca AI provider, so every model becomes selectable for inference — the installer writes this MCP entry and the provider block.

Paytaca app · AI

Your keys and sessions,
in one place.

The Paytaca wallet app has a dedicated Paytaca AI panel. Manage the keys your coding agent uses, watch time credits tick down, and buy the next plan when you need it — all without touching the terminal.

API keys, wallet-bound

Mint an sk-pytc-… key shown once, rename or revoke it later, and watch per-key usage. Keys also live in secure device storage.

Sessions at a glance

One active session per model with time credits used and remaining. Statuses read active, exhausted, or expired — never a mystery balance.

Buy in the app

Pick a model, pick 15, 30, or 60 minutes, then confirm with your PIN or biometrics. The plan lands as a session you can start using.

Security

Your keys never leave
your machine.

01
Keychain, never a file

The wallet mnemonic is written straight to the OS secret store. There is no plaintext key file to leak.

02
Wallet-bound API keys

Agent keys are minted against your wallet, stored hashed server-side, and shown to you exactly once.

03
On-chain verification

x402 payments are checked against the server’s own reservation on Bitcoin Cash — a forged receipt is not a payment.

04
Spend approval

buy_plan, send, and auto_refill ask the host before they move funds, and auto-refill stops at its cap.

Get started

Fund a wallet.
Buy minutes. Start coding.

Everything runs through one CLI. Install it, create a wallet, send BCH, and buy time credits — then point your agent at it. Node.js 20 or newer. macOS, Linux, and Windows, with your seed kept in the system keychain.

View on npm
sample purchase15 min · DeepSeek V4.1 Flash

Pay in BCH, or add --lift to pay with LIFT tokens and take the discount on the same plan.

Optional · swap BCH for LIFT and save 10%

LIFT-priced plans are discounted, so it can pay to convert first. Both directions go through the same command — this buys LIFT with BCH.
