Policy-driven pre-execution decision for autonomous agents, based on custom verification checks.

Decide whether an HTTP failure is safe to retry and return an idempotency-aware policy. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Records an agent decision (execute now, or wait) against a fresh forecast snapshot and returns a decision_id plus the block at which the outcome becomes checkable. Nothing is predicted here beyond the snapshot: this is a tamper-evident journal entry so the agent can later prove what it knew and what it chose.

Decision verdict for prediction markets: probability, direction and multi-source evidence with declared sources. $0.05 USDC x402 Base.
