Discovery pack · Autonomous buyers, wallet operators and payment engineers

Validate a Base payment before an agent spends

Validate caller-supplied Base gas context with deterministic budget, freshness, fee, USDC amount, recipient, payment-match and receipt checks before an autonomous buyer spends. The pack is read-only and validation-only: it never fetches chain state, signs, broadcasts, approves or transfers assets.

Every route below has its own price, schema and bounded AgentCash command. Copying a command preserves this pack as a measurable discovery source.
