# YourAITools

> Directory of AI tools, APIs and agent services that accept crypto payments, mostly USDC over the x402 protocol on Base and Solana. 283 listings in 14 categories (279 via x402). Each listing shows the payment protocol, networks, tokens, typical price per call and the public source it was verified from. Basic listings are free. Paid options (a Featured placement at $29 USDC for 30 days, labeled "Sponsored" ad slots and a Pro data feed) are always labeled and never change a listing's verification data.

Data last updated: 2026-10-21. Most listings come from the public Coinbase CDP x402 Bazaar discovery index or x402scan, with the paid endpoint probed for its 402 terms where noted; the rest were checked against the provider's own site or docs. A listing is not an endorsement. Nothing here is financial advice.
