ActiveTool of com.theaslangroupllc.pulse/pulsenetwork
MailPulse: The fleet's first ACTION origin — does something in the world instead of answering a question. Sends a real physical letter (US First-Class, US Certified with optional electronic return receipt, or international) via USPS through Lob's Print & Mail network: paying causes real postage to print and mail, once payment settles. Free address-deliverability check precedes the paid send; free price quote locks the exact price for 15 minutes; cheap status/tracking poll follows up afterward. Every response reports mode: "test" | "live" — test mode costs nothing and mails nothing physical. Coverage: US + international mail via USPS/Lob Endpoints: • verify-address ($0.01): Verify a mailing address (US + international) • letters ($3.00): THE paid action: prints and mails a real physical letter via Lob once payment settles. Price varies by service — standard $3.00, certified $12.00, certified_return_receipt $14.00, international $5.00 — the amount shown here is the representative/minimum price; the actual x402 charge always matches the caller's quote_id-verified order from POST /api/quote (free, no x402 gate). Requires a client_request_id (8-128 chars) for idempotency. • {id} ($0.005): Letter status / USPS tracking poll • health (FREE): Liveness + current mode
