# Datoka Agent — purchase help and support

Preparation and signature verification are free. Buying a receipt requires an x402-capable client and your explicit wallet authorization. Adding an MCP URL alone does not authorize spending. Check the network, asset, recipient and amount in the current /pricing offer before signing.

## What the receipt means
You receive a signed record of your declaration, not independent confirmation of an execution or HTTP exchange. A receipt is not an invoice or a certification of factual accuracy. Keep the receipt and your original purchase state privately.

## Payment pending, timeout or missing response
Do not buy again. Preserve the original event, idempotency key and signed authorization in the purchase state file. Resume with the same client and unchanged state; do not generate a replacement authorization, even after expiry. A timeout or an expiry alone does not prove that settlement failed.
If recovery still fails, stop automatic retries and contact support. Never delete the purchase state to restart. Support cannot reconstruct a lost private state file from a screenshot.

## Integration or verification error
A 402 response can be a price offer rather than a charge. Read the error body. Fix invalid input before signing. For a pending purchase, preserve the original input instead of changing it under the same key. Verify receipt signatures with independently trusted issuer keys; settlement and signature verification are separate checks.
Direct HTTP purchase and recovery have been qualified. Paid forwarding through every directory or intermediary has not been qualified; in particular, API paid forwarding through Smithery is not validated. Agent has testnet and historical-recovery evidence through Smithery, not a new mainnet purchase qualification through that relay.

## Contact support or request a payment review
Email contact@datoka.dev with the product name, date and time (including timezone), operation, error code and a public transaction hash if available. State whether you are requesting technical help, a refund review or a billing document. A support request is not an automatic refund or a guarantee of eligibility; no automatic refund service is advertised on this page.
Do not send private keys, seed phrases, bearer tokens, signed payment authorizations, purchase state files, raw prompts, request bodies or private customer data. Keep those files on your device. Send only the minimum non-secret information needed to identify the problem.
