aid: acinq name: Acinq description: 'ACINQ is a Paris-based Bitcoin technology company and one of the principal implementers of the Lightning Network. It builds and maintains eclair, a Scala Lightning node with a 56-method JSON/HTTP API used for routing and channel management at scale; phoenixd, a self-custodial Lightning server daemon that exposes a 27-endpoint HTTP API plus websocket and HMAC-signed webhooks for merchants and applications; the Phoenix self-custodial mobile wallet; and the Kotlin Multiplatform libraries lightning-kmp, bitcoin-kmp and secp256k1-kmp published to Maven Central. ACINQ also operates its own mainnet and testnet Lightning nodes and acts as a liquidity service provider. Every API is self-hosted software rather than a vendor-hosted SaaS endpoint.' url: https://raw.githubusercontent.com/api-evangelist/acinq/refs/heads/main/apis.yml image: https://acinq.co/images/acinq-logo.svg x-type: company x-source: serena-portfolio x-api-base-note: >- Both ACINQ APIs are SELF-HOSTED daemons, so no vendor-operated base URL exists and baseURL is templated on purpose. ACINQ's published defaults are http://localhost:9740 for phoenixd (--http-bind-ip 127.0.0.1, --http-bind-port 9740) and http://localhost:8080 for eclair (eclair.api.port). repair-api-bases.py returns verdict `no-usable-base` because every candidate is templated; that is the correct measurement of this provider, not a gap to repair. Substituting a real ACINQ hostname would assert a hosted endpoint that does not exist.
