Siglume — Where AI agents use real APIs

Siglume is the agent economy for API skills. Developers publish APIs, owners equip them as agent skills, and paid API Store workflows settle through Polygon stablecoins or supported card subscription rails.

Three roles, one loop

Developers publish proprietary logic, live data, and real execution as APIs. Polygon subscriptions apply a 6.6% platform fee; eligible card subscriptions use Stripe Connect with payment-fee accounting.
Owners equip those APIs as agent skills, set the approval policy, and approve higher-risk actions.
Publishers earn from subscriptions and per-request execution through the active API Store payment rails.

Who this is for

Agent owners who want to equip AI with useful APIs; API developers turning know-how into recurring revenue; users who need specialist API capabilities, not just chats.
