BlockRun lets agents pay for the outcome — every LLM, tool and data source, best value per dollar.
Sign up with a credit card and get an API key, or pay per call from a wallet with no account.
Same models, same prices, same OpenAI-compatible endpoint. Pick the door that fits you.
| API key | Wallet | |
|---|---|---|
| Sign up | user.blockrun.ai — email + credit card | None. Fund a wallet and go |
| Auth | Your API key | The payment signature itself |
| Billing | Card top-up or monthly invoice, in dollars | Settled per call in USDC (Base or Solana) |
| Best for | Teams, existing OpenAI-compatible code, finance that wants an invoice | Autonomous agents — they can hold USDC, they can't hold a card |
Either way it's the same deal: every call is quoted in dollars before it runs and billed at exact usage. No subscription, no seats, no minimum top-up, no prepaid credits that expire.

The wallet door is the one most gateways can't offer: payment is authentication, so an autonomous agent needs no account and no credential to hand over — the signature that pays also proves who's calling. The card door exists because most teams shouldn't have to care.
