Available prepaid API · deterministic JSON checks
Check duplicate conflicts and sequence gaps in event JSON.
Inspect a supplied event batch before your pipeline imports or replays it. Return explicit findings for your own review logic, without pretending to observe an external delivery.
No account or card for the browser tool. The browser report is unsigned; paid API calls return an ES256-signed report after payment confirmation.
Where it fits in an automation
Insert a check between a webhook-event export and your batch import. Review conflicting duplicate IDs and sequence continuity within each declared stream. Timestamp ordering requires caller-declared same-clock conditions. The service reports supplied declarations and does not subscribe to a provider or repair events.
A batch contains 1–200 supplied JSON events, with a maximum input of 64 KiB. No independent proof that an event occurred, a message arrived or a provider signed it. This is a one-off batch check, not a continuous monitoring service or delivery certification.
A fictitious example you can inspect
The input below is a complete synthetic paid-API request. The output shows selected analysis fields calculated by the actual free browser core; it is not a signed receipt, a customer result or evidence of a paid transaction.

Price and purchase
EUR 0.002 excluding tax per batch of up to 200 events. Choose your exact total payment from EUR 10 to EUR 10,000, including applicable taxes. The net amount becomes a shared tax-exclusive balance for the three available services.
One-time payment, no subscription, no automatic recharge. Save your private recovery code before confirming payment; API access starts only after server confirmation. Different API capacities are alternative uses of one balance and cannot be added together.
A valid analysis with findings is charged; invalid input consumes no credit. Save each returned report and signature yourself. The prepaid service does not archive reports.

Your saved private code is already your Bearer API access. Keep it in protected server configuration, never in a frontend, prompt or URL. Read GET /v1/status without a debit and proceed only when state is active.
POST https://pfxxzsnboehxsefyajml.supabase.co/functions/v1/xynthera-ai-payg/v1/events/check Authorization: Bearer YOUR_PRIVATE_BUDGET_CODE Content-Type: application/json Body: the complete JSON example above, reviewed before execution.
Use a new request_id for a new check. After an uncertain response, deliberately retry the identical body and identifier, not a fresh request. Limited reconstruction metadata lasts 30 days; it does not replace your report backup or expire the commercial balance.
Remote MCP uses protected custom Bearer headers, not OAuth. No universal client compatibility, automatic purchase or supplier payment is promised.
