Lightspark
Lightspark builds global money-movement infrastructure on open payment networks. Its developer product is the Grid API — a dated-version REST API (OpenAPI 3.1, 104 paths, 564 schemas, 12 webhooks) for cross-border payouts, on/off-ramps, stablecoins, embedded wallets, card issuing, KYC/KYB verification and payments to Universal Money Addresses ($user@domain). Grid is unusually agent-native: it ships a first-class agent surface with device-code credentials, per-agent policy and human-in-the-loop approvals, a hosted MCP server, a published Claude agent skill, an open-source CLI, and generated TypeScript and Kotlin SDKs. Lightspark also operates the Spark and UMA protocol stacks and is backed by a16z, Matrix Partners, Paradigm and Ribbit Capital.
Lightspark publishes 23 APIs on the APIs.io network, including Agent Management API, Agent Operations API, API Tokens API, and 20 more. Tagged areas include Company, Payments, Cross-Border Payments, Stablecoins, and Bitcoin.
The Lightspark catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Lightspark’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 38 more developer resources.
