  x-guidance: 'All paid operations use x402 on Solana: call without payment to get a 402 challenge (SOL recipient + USDC token account + fresh memo), pay with the memo attached via the Solana Memo program, then retry with header X-Payment-Tx: <signature> and ?toll_memo=<memo>. Challenges are dual-version: the PAYMENT-REQUIRED header carries the x402 v2 PaymentRequired object and the response body carries the same challenge in x402 v1 form for compatibility. Free operations (security: []) include each service''s /health catalog with full response shapes. Prices in x-payment-info are USD per call unless the summary says otherwise (RPC is per 1,000-request block; Telegram provisioning is per bot-month; transcription is per minute of audio).'
  description: '67 data and utility APIs behind x402 tolls, settled in SOL or USDC on Solana. Call a paid endpoint without payment to receive a 402 x402 challenge (recipient + fresh memo), pay with the memo attached via the Solana Memo program, then retry with the X-Payment-Tx header and toll_memo query parameter. Free catalog/health endpoints are marked without x-payment-info. Full catalogs: GET /toll/discovery and each service''s /health.'

                recommendation: You have enough energy and bandwidth — this transfer costs 0 TRX in fees. Energy figure comes from on-chain simulation of your exact transfer. Your TRX balance covers the worst case — safe to proceed.
