This endpoint requires x402 payment — your agent wallet will automatically pay ~$0.10 USDC on Base when the server returns HTTP 402, then retry. POST https://extraordinary-charisma-production.up.railway.app/api/smspva/buy Content-Type: application/json { "country": "US", "service": "opt7" } Supported country codes: US, GB, FR, DE, IN, BR, PH, ID, NG, RU, UA, PL, CA, AU, MX, and 60+ more. Success response (200): { "statusCode": 200, "data": { "phoneNumber": "14155552671", "orderId": "abc123", "orderExpireIn": 600 } } The full number to enter on the website is: +{countryCode}{phoneNumber} (e.g. +14155552671 for US numbers). If you get a non-200 response, try a different country or service code and call buy again. ### Step 3: Use the Number on the Website Use your browser to: Navigate to the website's signup or phone verification page Enter the phone number in international format (e.g. +14155552671) Click the "Send code" / "Verify" / "Get OTP" button Wait for the page to confirm the SMS was sent ### Step 4: Poll for OTP After triggering the SMS, poll every 15 seconds: GET https://extraordinary-charisma-production.up.railway.app/api/smspva/otp/{orderId} OTP received (200): { "statusCode": 200, "data": { "sms": { "code": "123456" }, "orderId": "abc123", "orderExpireIn": 540 } } Extract data.sms.code — that is your OTP. Not yet received (202): wait 15 seconds and retry. Stop polling if: You receive status 200 (success) orderExpireIn drops to 0 (order expired — start over) You receive status 410 (order closed) ### Step 5: Enter the OTP Go back to the browser tab and enter the OTP code from data.sms.code into the verification field. Submit the form to complete signup. ### Error Recovery Number doesn't work / site rejects it: PUT https://extraordinary-charisma-production.up.railway.app/api/smspva/refuse/{orderId} Then go back to Step 2 and buy a new number. Number is banned by the service: PUT https://extraordinary-charisma-production.up.railway.app/api/smspva/ban/{orderId} Then buy a new number with a different country. ### Full Example Flow User: "Sign me up on Telegram with a US number" Call POST /api/smspva/buy with { country: "US", service: "opt1" } Get back phoneNumber: "14155552671", orderId: "x9k2m" Open browser → navigate to https://web.telegram.org → start signup Enter +14155552671 as the phone number → click Send Code Poll GET /api/smspva/otp/x9k2m every 15s Receive { sms: { code: "84712" } } Enter 84712 in the Telegram verification box → account created ✅ ### Notes Numbers are single-use and expire after orderExpireIn seconds (typically 5–10 minutes) Always use international format with + prefix when entering the number on websites Some services block certain countries — if one country fails, retry with a different one The x402 payment (~$0.10 USDC) is charged per number purchase, not per OTP poll ## Trust - Source: tencent - Verification: Indexed source record - Publisher: 0xShadowETH - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-29T04:42:09.020Z - Expires at: 2026-05-06T04:42:09.020Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/shadow-phone) - [Send to Agent page](https://openagent3.xyz/skills/shadow-phone/agent) - [JSON manifest](https://openagent3.xyz/skills/shadow-phone/agent.json) - [Markdown brief](https://openagent3.xyz/skills/shadow-phone/agent.md) - [Download page](https://openagent3.xyz/downloads/shadow-phone)
