FAQ

Is craft-pricing useful for an Etsy seller?

Yes. Feed it your item description, material list, and target margin. It returns a comparable price band, channel-specific math (Etsy fees vs direct), and positioning tips. Cheap enough to re-run on every new listing.

What's the agent-trust endpoint actually for?

Agent-to-agent commerce — one bot wants to call another bot's paid API and needs to assess reliability before sending USDC. Returns a 1-100 trust score with rationale grounded in uptime, payment success rate, SLA history. Built for the x402 ecosystem itself.

Can I use lead-score in a real sales workflow?

Yes — as a first-pass triage layer. Don't replace human judgment on enterprise deals, but for indie SaaS and DTC ecommerce, an autonomous scoring layer at $0.05/lead beats spreadsheet rubrics. Pair it with a CRM webhook.

Why pay-per-call?

Indie sellers and one-person ops can't justify $100/month for an underused tool. Pay-per-call means a $5/year hobbyist and a $50,000/year shop can use the same API at proportional cost. No upgrade friction.

How do I pay without a Coinbase account?

Any wallet on Base with USDC works. EIP-3009 transferWithAuthorization — sign off-chain, facilitator settles. No KYC, no signup.
