Buy paid placement in the agent-exec directory of live x402 services: a promoted listing outranks free ones while paid, and demotes automatically the moment payment lapses. This entry buys the day plan ($0.0667). Week and month plans are also sold -- read the live price table from https://agent-exec.45.67.221.128.sslip.io/.well-known/x402.json rather than trusting a cached figure. Payment buys position only: it is not a review, and does not verify or endorse the listing. Create the listing first with a free, accountless POST /listings (wallet signature, no signup), then promote it by id. No account, no API key.
