Tweed

Tweed is an Accel-backed embedded-crypto platform offering Wallet-as-a-Service and NFT/token checkout APIs.

A REST API (V2) manages contracts, items, payouts, checkouts, and HMAC-signed webhooks; note the marketing site and dashboard host were unreachable as of July 2026 while the docs, API, and npm SDKs remain live.
