# Light **Canonical:** https://apis.io/providers/light/ **Website:** https://light.inc/ **APIs profiled:** 1 Light is an agentic accounting and financial-operations platform positioned as an alternative to traditional ERPs and fragmented finance stacks. It combines a multi-entity general ledger and consolidation engine with accounts payable, accounts receivable, spend management and corporate cards, contracts and subscription billing, purchase orders and expense reimbursement. The Light API is a REST API over HTTPS returning camelCase JSON, covering 183 operations across 28 resource groups — invoice payables and receivables, credit notes, customer credits, journal entries, ledger accounts, bank accounts and transactions, cards and card transactions, contracts, purchase orders, products, vendors, customers and users. Authentication is either an API key sent as HTTP Basic or an OAuth 2.0 access token, access is governed by the same roles as user accounts, and writes on 14 operations accept an X-Idempotency-Key header. Light also publishes a live Model Context Protocol server over its documentation and markets a Claude MCP integration against the live ledger. ## Kin Score — 48.8 / 100 (developing) Scored 2026-08-30 under rubric 0.17.2.
