x402 Pay-Per-Call Protocol — Live on Base

Mapping the Brain& Tools of AI

We turn the black box of LLMs into a vectorized inventory of x402 endpoints. This reveals what's possible, eliminates overlap, and opens the possibility of truly autonomous AI.

How It Works

x402 Access

We use x402 to make API endpoints accessible to AI. One wallet, pay-per-call, no keys.

Discovery

Map the Brain

Turn the black box of LLMs into repeatable, structured endpoints with schemas and examples.

Evaluate Over Time

Track cost, quality, and speed of every tool. Compare models, versions, and providers as they evolve.

Evals

Tokenize the Best

The highest-performing tools get their own token. Usage drives value, speculation meets utility.
