SQLPermit

x402 resource x402 REST

sqlpermit.schemasure.com · sqlpermit.schemasure.com · Databases & Storage

Decide whether an agent-authored PostgreSQL statement complies with an execution policy, using PostgreSQL's own parser rather than pattern matching. Detects statement stacking, data-modifying CTEs, COPY PROGRAM, privilege changes, and dangerous functions that read as ordinary SELECTs. Returns reason

Blockchain wallets

Full addresses · public payment evidence

Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

Sending wallets · observed counterparties

No sending wallet addresses have been retained for this service. Buyer wallets are unknown; daily totals and reported payer counts do not reveal their addresses.

Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.

Opportunity insights

2 findings from measured data
  • Payment attribution is blocked

    The payout address is shared with 8 other service(s). That is normal for facilitator and platform addresses, and it is why this profile shows no inflow figure. The volume exists — it just cannot be split without inventing a rule.

    How attribution works →
  • Category benchmark

    11 of 2,077 services (0.5%) in Databases & Storage have attributable inflows; 305 have a source-measured call count. Median measured calls: 2.

What the provider says

Decide whether an agent-authored PostgreSQL statement complies with an execution policy, using PostgreSQL's own parser rather than pattern matching. Detects statement stacking, data-modifying CTEs, COPY PROGRAM, privilege changes, and dangerous functions that read as ordinary SELECTs. Returns reason codes and an optional short-lived signed permit bound to the exact normalized statement. Never connects to your database.

Attribution Shared
Receipt ledger Not connected

Attribution blocked · confidence low
The payout address is also published by 8 other service(s); the volume cannot be attributed to one of them.

Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is an activity value of $0.32 — the source's call count multiplied by the published price. That is what the list price implies, not what anyone paid. The payout address is also published by 8 other service(s); the volume cannot be attributed to one of them.

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it.

Provenance

One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
