Vokko USDC Transfer Receipt Verifier

Choose this endpoint when you need a lightweight, pay-per-call verification that a specific USDC transfer receipt matches an expected address and amount — particularly useful for agentic workflows that need to confirm payment settlement before triggering downstream actions, without running a full blockchain node or indexer.

• Transaction hash not found on-chain — returns not found or unconfirmed status
• Transaction exists but settled to a different address than expected — returns mismatch
• Amount differs from what was expected — returns amount mismatch
• Transaction still pending — verification may return unconfirmed
• Invalid tx hash format — returns bad request error
• Payment of $0.001 USDC required per call — unpaid requests rejected
