agent402.tools · x402

OpenAI-compatible text-to-speech over x402 - point any OpenAI SDK's audio.speech.create() at base_url https://agent402.tools/v1 and pay $0.06 per call in USDC, no API key, no signup. Served by Voxtral Mini TTS behind a five-model failover chain (xAI Grok Voice, Kokoro, MAI-Voice-2.1 Flash, MAI-Voice-2.1), every link proven by a real paid canary - a provider outage never becomes your failure. Up to 2,000 chars in, raw mp3 (default) or pcm bytes out - the same wire shape as OpenAI's endpoint.

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.

Counted by addrbook from USDC transfers to the wallets it asks to be paid at, on Arc. A payer is independent when it is not one of the seller's own wallets and the seller did not fund it; the largest payer made 39.2% of the payments. Counted . How payers are counted
