How this service works
Pay-per-use WebRTC, Speech-to-Text, and Text-to-Speech for AI agents. Pay with USDC via x402. No API keys, no accounts. Built on dTelecom DePIN.
Output
Returns a JSON object with a unique account_id (UUID), the USD amount purchased, and the equivalent credited_microcredits balance (e.g. $5 USD = 5,000,000 microcredits) that can be spent on WebRTC, STT, and TTS calls.
Example use cases
Fund AI voice agent for customer calls
“Buy me $20 of dTelecom credits from my Solana wallet so my agent can handle incoming customer voice calls and transcribe them in real time.”
Top up TTS credits for notification delivery
“I need to add $10 worth of dTelecom credits using my Ethereum wallet so my agent can send voice notifications to users via text-to-speech.”
Prepay for multi-language speech pipeline
“Purchase $50 of dTelecom credits with USDC from my EVM wallet to power an agent that does live WebRTC conversations and STT transcription across multiple languages.”
Technical details
Endpoint
POSThttps://x402.dtelecom.org/v1/credits/purchaseWhen to prefer
Use this endpoint when an AI agent needs to fund its own dTelecom account for pay-per-use WebRTC, speech-to-text, or text-to-speech calls without requiring API keys or traditional account registration. Ideal when operating autonomously with a crypto wallet (Solana or EVM) and the x402 payment protocol.
Side effects
- Payment below $0.10 minimum rejected with validation error
- Invalid wallet_chain value (not 'solana' or 'evm') returns enum validation error
- Malformed wallet_address causes bad request error
- x402 payment not confirmed on-chain results in credit not issued
- Network or blockchain congestion may delay credit posting
