Networks & assets
Agentic payments move money through the same rails as the rest of the platform — anything your wallets can send, an agent-drafted payment can send:
Sandbox examples throughout these docs use
base-sepolia, ethereum-sepolia, and solana-devnet with USDC.
Mandate rule bounds
A mandate holds exactly one rule; authority is extended by additional mandates, never by editing (mandates are immutable once created).
Every cap is enforced at fire time by the mandate gate — a schedule that outgrows its mandate fails with
mandate_denied rather than firing.
Conversation & drafting caps
Budget overruns return
429 with a Retry-After-style problem body; input-cap violations return 400 before any model spend.
Platform-wide limits that apply here too
- API rate limits — the standard per-key limits apply to every agentic endpoint; see Rate limiting.
- Idempotency — every agentic
POSTrequiresX-Idempotency-Key, like the rest of the platform. - Sandbox amount cap — sandbox caps transactions at $2 USD-equivalent per transaction by default, agentic ones included. Drafts above the cap actuate but fail at fire time, exactly as an over-cap direct send would.
