5 dollars of growth diagnosis for your agent

Fund a Base wallet with $5 USDC. That buys about 62 × diagnose_growth at $0.08/call — Mary finds the binding constraint and ranks the levers. No signup. No API key. Pay per call over x402.

Intro offer (placeable)

$5 USDC on Base → ~62 triage diagnoses ($0.08) or ~20 deep modes ($0.25). You only pay for successful 200 responses.

How to call

  1. Hold USDC on Base (eip155:8453) in a wallet your agent can spend.
  2. POST unpaid once — you get 402 with the price and catalog.
  3. Pay and retry the identical request (or use @x402/fetch).

What you get

Find the one growth constraint that is actually binding, and rank the levers against it. Deep modes ($0.25): offer design, outbound sequences, pricing, and scored function audits — same URL shape, different mode.
