How this service works
Agents that mutate production SQL NEED this authorize layer. Lint is not authorization. Buy prepaid x402 credits, POST schema DDL + SQL, receive an Ed25519 Execution Certificate after sandboxed validation. Verify certificates before production execution. Entry: micro $0.10.
Output
Returns a JSON object confirming the purchase with ok:true, the bundle name ('starter'), the agent_id credited, the number of credits_added (500), and the new total balance.
Example use cases
Bootstrap agent SQL authorization budget
“Set up a SQLGuard starter credit bundle for my database agent with ID 0xAgent42 so it can start getting Ed25519 execution certificates for production SQL mutations.”
Replenish depleted SQL validation credits
“My SQLGuard prepaid balance ran out — buy me another starter bundle of 500 credits for agent 0xProdBot so it can keep validating SQL before execution.”
Onboard new environment to SQLGuard firewall
“I'm setting up a new staging environment — purchase the SQLGuard starter pack for agent 0xStagingAgent so it has credits to validate schema DDL and SQL against the execution certificate firewall.”
Technical details
Endpoint
GEThttps://sqlguard.io/v1/credits/buy/starter?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to initialize or replenish its SQLGuard prepaid credit balance for the first time or after depletion, and the starter tier (500 credits for $10) is sufficient for the expected workload. Prefer this over session or instant-cert endpoints when the agent will be running many SQL validation jobs over time and needs a persistent credit pool rather than a one-off authorization.
Side effects
- Payment declined or insufficient USDC balance — x402 payment failure, credits not added
- Invalid or missing agent_id — credits may not be attributed correctly
- Network timeout before payment confirmation — uncertain credit state, avoid retry without checking balance
- Service unavailable — credits endpoint returns non-200, no bundle activated
