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: ok=true, bundle name ('builder'), total credit balance after purchase, credits added (2500), and the agent_id the credits were assigned to.
Example use cases
Pre-fund agent SQL authorization pipeline
“My database agent is running low on SQLGuard credits — buy me the builder bundle to top up 2500 credits so it can keep issuing execution certificates for production SQL changes. My agent ID is 0xProdAgent42.”
Onboard new agent with starter credits
“I'm setting up a new SQL mutation agent and need to seed it with SQLGuard credits before it goes live — grab the builder pack for agent 0xNewDeployAgent so it can start getting certified.”
Automate credit replenishment check
“Check if my SQLGuard builder credit balance needs a refill for agent 0xAutoSQLBot — if it does, go ahead and purchase another builder bundle to keep the execution certificate pipeline running.”
Technical details
Endpoint
GEThttps://sqlguard.io/v1/credits/buy/builder?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pre-fund a SQLGuard account with the entry-level 'builder' bundle ($0.10 for 2500 credits) before running SQL execution certificate workflows. Prefer this over session burst or pilot challenge packs when you want low-commitment, fine-grained prepaid credit top-ups rather than session-scoped or volume-unlock packages. Use this as the first step before calling validate or verify endpoints.
Side effects
- Payment failure or insufficient USDC balance — payment not processed, credits not added
- Invalid or malformed agent_id query parameter — may return error or assign credits to default address
- x402 payment protocol misconfiguration — 402 response without credits being granted
- Rate limiting or duplicate purchase detection — credits not added if request is flagged as duplicate
- Network timeout during payment processing — ambiguous state where payment may or may not have settled
