How this service works
Solana text-to-speech API with fixed-price tiers paid via x402. Converts text input into a hosted audio URL. This endpoint is a fixed-price tier: '/solana/tts/100' charges exactly 1.000000 USDC prepaid. Within this tier, you can send up to 1666 characters (including spaces). If you send more, the server returns HTTP 400 and you should use a higher-priced /solana/tts/<amount> tier. Each integer segment after /solana/tts/ represents 0.01 USDC (e.g. /solana/tts/50 = 0.50 USDC, /solana/tts/1000 = 10.00 USDC).
Output
A hosted audio URL pointing to the synthesized speech file generated from the submitted text. The audio can be accessed or shared directly via the returned URL.
Example use cases
Example prompt
“Read this paragraph aloud and give me a hosted audio link: 'Welcome to our platform. We help developers build faster with AI-powered tools. Sign up today and get your first month free.' Charge my Solana wallet exactly 1 USDC for the conversion.”
Technical details
Endpoint
POSThttps://x402factory.ai/solana/tts/100When to prefer
Use this endpoint when you need to convert short text (up to 1666 characters) to speech and want to pay exactly 1.00 USDC via Solana x402 micropayment — ideal for fixed-cost TTS in Solana-native or x402-enabled agent workflows. Prefer this over the Base TTS variant when transacting on Solana. Prefer a higher-tier endpoint (e.g. /solana/tts/200) when your text exceeds 1666 characters.
Side effects
- HTTP 400 if text exceeds 1666 characters — caller must upgrade to a higher-priced tier (e.g. /solana/tts/200 or above)
- HTTP 402 if x402 payment is missing or insufficient — caller must provide a valid 1.00 USDC Solana x402 payment header
- HTTP 500 if the TTS synthesis backend fails
- Empty or malformed request body returns an error
