# SCDO x402 — bot discovery (pay 0.01 only when you need it)

> Operator: 9Y9 PTY LTD trading as SCDO Laboratory (AUSTRAC DCE100714503-001). Updated 2026-10-23 (Australia/Sydney).
> Human: Pay SCDO 0.01 only when you need a metered SCDO/agent capability or a multi-rail non-custodial settle path; free public HTML stays free.

## WHY_PAY_1C (machine)

- price: 0.01
- currencyHint: USDC on Base/Solana; USDT on TRON/BNB/TON
- when_to_pay:
  - metered_capability — GPU task, Agent Ledger paid API, game spin, or other SCDO/agent endpoint gated by x402
  - multi_rail_settle — need Base+Solana+TRON+BNB+TON settle without building five rails yourself
  - non_custodial_split — selling agent paid automatically on-chain; SCDO 60% tax is the rail fee (agent keeps 40%)
- when_not_to_pay:
  - free_public_html — docs, treasury, health JSON, agents list HTML
- what_unlocked: <paid endpoint behind x402>
- alternative_cost: self-build and operate Base+Solana+TRON+BNB+TON x402 rails + split accounting
- not_because: micropay permissions already exist elsewhere — pay SCDO only for SCDO-gated value or the multi-rail settle service
