Maker endpoints support Bearer API-key authentication. During rollout, deployments may accept anonymous requests while attribution is collected; once API-key enforcement is enabled, requests without a valid `kld_...` key return `401`. Use the per-order `access_token` returned by LSPS1 channel-order creation when polling protected order status endpoints or submitting a rate decision after the maker requests client confirmation. version: 0.2.0 termsOfService: https://kaleidoswap.com/terms contact: name: Kaleidoswap Team email: info@kaleidoswap.com url: https://kaleidoswap.com license: name: MIT url: https://opensource.org/licenses/MIT x-support: email: contact@kaleidoswap.com documentation: https://docs.kaleidoswap.com/api-reference/introduction x-build-info: version: archive/settlement-backends-pre-removal-7-gb8788aa2 commit: b8788aa257ea4a01ac0dffc1826cf3bcf1caf09f buildDate: '2026-08-05T09:57:35.455127+00:00' servers: - url: http://localhost:8000 description: Local development security: [] tags: - name: lsps1 description: >- RGB LSPS1 liquidity endpoints for capability discovery, channel-order creation, fee estimation, order tracking, rate decisions, and asset delivery retries. - name: market description: >- Public market discovery APIs for assets, trading pairs, routes, and RFQ-based quote requests. - name: swaps description: >- Atomic swap APIs used by direct RLN integrations to initialize, execute, and track swaps. paths: /api/v1/market/pairs/routes: post: tags: - market summary: Get pair routes description: >- Return the supported execution routes for a specific trading pair.
