  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.'

Counts only: no buyer identity appears anywhere in the report. A count the submitted log cannot support is reported as NOT-COMPUTABLE, never estimated. A free pre-check validates the log''s shape before any payment and returns no counts. The submitted log is processed in memory only and is never stored; the payments ledger records only the payer, the time, the price, the headline counts, and the verdict line. The response body carries the payment instructions in x402 v1 form: payTo (the operator''s Solana wallet), the amount (20000 USDC units = $0.02 per log) and a fresh memo. Pay in USDC on Solana with the memo attached via the Solana Memo program, then resubmit the same request with the payment transaction in the X-Payment-Tx header and ?toll_memo=<memo>, re-sending the request body. The PAYMENT-REQUIRED response header carries the same object in x402 v2 form.'
