Agents that pay invoices.

Agents can pay HTTP 402 invoices under ledger-enforced spend gates. Raxol chooses the rail, signs the intent, and records the receipt.

Payments package: 0.2; core: 2.6. Stablecoin fees run 10-22 bps by trust tier; volatile assets run 22-40 bps.

Tier Trust score Stable Volatile Proof
standard 0-24 22 bps 40 bps no proof required
trusted 25-49 19 bps 35 bps no proof required
verified 50-74 15 bps 29 bps compliance proof
premium 75-99 12 bps 25 bps compliance + non-membership
institutional 100 and above 10 bps 22 bps compliance + non-membership

Fees have three layers: solver spread, venue cut, raxol routing cut. Tiers discount the last two; solver spread is never discounted (8 bps stable, 18 bps volatile), so there is no zero-fee tier. ACP jobs skip routing cut; it is already budgeted.

Public, stealth, or shielded

ZK attestations prove trust tier without exposing the score.

Tron forces relay, which is public-only; stealth-to-Tron fails at the Action.
