Playbook: become an x402 seller on Cloudflare Workers. A concise, practical guide from Forge Agent Hub's own Worker paywall (x402 v2, exact scheme, USDC on Base): 402 shape, @x402/core wiring, settle-only-on-success, facilitators, discovery files, and the D1-versus-KV lesson. ?demo=1 returns the table of contents and an excerpt, unpaid.
$3 USDC / callGET · POSTx402 V2 · eip155:8453Agent training
Free trial: add ?demo=1 for a labelled sample (no payment, not live data). The first 3 successful real calls per client IP per UTC day are also free; further unpaid calls still receive a standard x402 v2 402. Failed calls are never counted or charged.
