Put your API where agents can find it.

The SML Provider Marketplace is a free-to-browse directory where a provider publishes an API or tool for a one-time $0.01 USDC listing fee on Base via x402 v2. SML charges the directory-listing fee only; your listing keeps your own endpoint and seller-supplied payment destination, with no custody of buyer revenue.

Payment authority: the fresh HTTP 402 PAYMENT-REQUIRED challenge returned by the production listing endpoint. Cached page text is never the final payment authority.

What is the agent and developer contract for marketplace listings?

Discovery is free. Submit a valid provider listing without a payment signature to receive the exact x402 v2 terms, then retry the same request with a valid payment signature.

What is intentionally not offered?

Provider listing intake is live. Seller custody, marketplace-paid reads, balances, withdrawals, payouts and synthetic seller rankings remain quarantined until their accounting and settlement controls are independently proven.
