How this service works
Prepaid volume credits ($0.10 → 5) for SQLGuard validate/verify after Session or Instant. Not the primary authorize path — use Session Cert for authorize mutating SQL before execute.
Output
Returns confirmation of a prepaid micro-credit purchase (entry at $0.10 USDC), crediting the caller's SQLGuard account balance which can then be spent on sandbox validation and Ed25519 PASS certificate issuance for mutating SQL statements (INSERT, UPDATE, DELETE, DDL).
Example use cases
Fund automated database migration guard
“We're running a schema migration next week with a bunch of DDL and UPDATE statements — buy a batch of SQLGuard micro credits so our pipeline can get execution certificates before touching production.”
Prepay for ad-hoc production INSERT approval
“I need to do a one-off bulk INSERT into production and I want SQLGuard to sign off on it first — can you buy the credits I need to get that authorization certificate?”
Bootstrap SQL firewall for CI/CD pipeline
“Our new CI/CD pipeline needs to validate and certify every mutating SQL statement before it hits production — purchase SQLGuard micro credits to get the execution certificate firewall running.”
Technical details
Endpoint
GEThttps://sqlguard.io/v1/credits/buy/microWhen to prefer
Choose this endpoint when you need to prepay or top up credits for SQLGuard's SQL execution authorization system before issuing validation or certificate requests. Use this as the first step if your SQLGuard credit balance is zero or insufficient to cover upcoming mutating SQL statement validations. This is the entry-level ($0.10) credit purchase; prefer it for lightweight or one-off authorization needs.
Side effects
- Payment failure — insufficient USDC balance or x402 payment protocol error returns payment required error
- Invalid agent_id — unrecognized agent identifier may result in credit not being associated correctly
- Network timeout — slow payment settlement may leave credit purchase in pending state
- Duplicate purchase — non-idempotent endpoint may process multiple charges if retried without checking balance
