  56. 100agent402.tools/api/sql-cert-verifyVerify an Ed25519 execution certificate against the exact SQL statement you are about to run - the gate your database layer calls before it obeys an agent. Checks the signature, the certificate version, the expiry, and that the statement's SHA-256 matches the one certified, so a certificate for a different (or edited) statement is rejected. Returns { valid, reason, payload } and never throws on a malformed token, so the executor always gets one uniform answer.$0.001 Base114 ms1 payers100% up
  57. 100agent402.tools/api/moving-averageCompute simple (SMA) and exponential (EMA) moving averages over a numeric series.
