OpenAI-compatible drop-in replacement

Save 79% on every AI request

Whether you're coding with Cursor or running autonomous agents like OpenClaw — PennyPrompt classifies every request, optimizes token usage, and routes it to the best model for the job at the lowest cost. Pay-per-use with USDC on Base.

Two ways to pay

[>_]

For humans

OpenCode, Cursor, SDK, curl

Deposit USDC to your HD wallet on Base. Each request is deducted from your balance. Pay-per-use — no subscriptions, no minimum.

{::}

For autonomous agents

OpenClaw & x402-compatible agents

Your agent pays per-request from its own wallet via the x402 protocol. No API key needed — payment is the authentication.

How it works

$_01

Choose how to pay

Deposit USDC on Base for human-operated tools, or use x402 for autonomous agents. Both are pay-per-use.

{::}02

Connect on /setup

Point your tool or agent at PennyPrompt. A two-line config change for most clients.

Intelligent routing

Each request is classified by complexity, tokens are optimized, then routed to the best model for the job at the lowest cost.

Two ways to pay

Humans deposit USDC on Base and spend from balance. Autonomous agents pay per-request via x402 — no API key, no deposit needed.
