{"slug":"delx-is-blank-87f4cb83","name":"Delx Is Blank","summary":"Check whether a string is empty or contains only whitespace. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.","status":"live","indexable":true,"listed_since":"2026-10-25T17:52:39.727662Z","sources":[{"source":"x402_bazaar","external_id":"https://api.delx.ai/api/v1/x402/is-blank","owner_address":"0x9f8bd9875b3e0b632a24a3a7c73f7787175e73a2","seen_at":"2026-10-26T06:00:59.249080Z","removed_at":null}],"endpoints":[{"url":"https://api.delx.ai/api/v1/x402/is-blank","host":"api.delx.ai","protocol":"x402","state":"live","last_probe_at":"2026-10-26T02:13:05.584257Z","last_ok_at":"2026-10-26T02:13:05.584257Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"api-delx-ai-a7d9aeff","name":"api.delx.ai"}],"payment_options":[],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":2,"last_paid_at":"2026-10-08T06:09:15.473Z","reported_at":"2026-10-26T06:00:59.249080Z"},"notice":"Not affiliated with addrbook — claim or request removal."}
