## Payment options

Two rails, same capabilities, no accounts required:

**Option A — Crypto (x402, agents and wallets):** Call any `/cap/` endpoint → receive `402 Payment Required` with the USDC price → pay on Base mainnet via the x402 facilitator → result returned automatically. No signup.

**Option B — Card (Stripe, humans and devs):** Buy prepaid credits once, then call any cap with `Authorization: Bearer ` — 1 credit per call, no gas, no per-call signing.
1. `POST https://the-stall.intuitek.ai/v1/fiat/checkout` with `{"bundle":"starter"}` → returns a Stripe checkout URL.
   - `starter` $5 / 100 credits · `pro` $30 / 1,000 credits · `scale` $200 / 10,000 credits
2. After paying: `GET https://the-stall.intuitek.ai/v1/fiat/token?session_id=` → returns your bearer token.
3. Add `Authorization: Bearer ` to any `/cap/` call.
