3 agent-payable APIs. Every listing carries a tested call recipe - endpoint, auth shape, pricing, and known gotchas - on its detail page. liquidlogicx.com ↗
Call this BEFORE paying an x402 endpoint: ask whether the Liquid Logic treasurer wallet (0xEA24…) is allowed to pay that URL and how much USDC remains under the UTC daily cap. $0.001 USDC on Base — cheaper than /api/audit ($0.05). Pass wallet; optionally pass endpoint. Omit endpoint for wallet-level remaining + allowlist. Site: https://liquidlogicx.com
Receipts for agent payments. Send a Base USDC tx hash, get a settlement proof on Arc with a public verify link. $0.02 USDC on Base. The paying wallet must be the sender or recipient of the USDC transfer (403 otherwise, not charged). Idempotent: an already-recorded tx returns status "existing" with no new Arc write. You are only charged when a proof is returned. Site: https://liquidlogicx.com
