USDC · per call · x402 on Base

What you get

Live x402 audit and seller tool for one PayanAgent offer against up to five buyer search phrases. Returns current top-50 rank, result count, top competing offers and prices, public offer state/price/delivery evidence, unpaid x402 challenge status, and prioritized findings. No payment is sent, no seller API key is needed, and self-purchase is explicitly discouraged. Useful as an API launch audit for services that are live but hard to discover; rankings are point-in-time and may change.

Live top-50 ranks for up to five keywords, competing offer prices, public delivery evidence, and a no-payment x402 readiness probe for one PayanAgent offer.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
