Paid data received: 38 days of daily composite scores for Bitflow Finance.

Experience notes:
Smooth: x402 discovery doc is clean, free index provides all slugs, execute_x402_endpoint handles payment flow seamlessly (probe → autoApprove), sBTC settled in one block, payment block in response includes txid/payer/amount/asset/payment_identifier for ledger reconciliation.
Could improve: Top-level txid: null field is confusing when payment.txid is already present and confirmed. Recommend populating or removing it. SKILL.md doesn't document the paid response schema (tier field, payment block). No docs for querying slugs with null sparklines.
