Normalised, chain-indexed vesting data from Sablier, Hedgey, Superfluid, LlamaPay, UNCX, Unvest, Team Finance, PinkSale, HoodLock, Magna, Streamflow, and Jupiter Lock – across Ethereum, Base, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Robinhood Chain, and Solana. Clean REST API with OpenAPI spec and native MCP support.
Indexed protocols
Why Vestream API
Every protocol speaks a different language on-chain. We translate everything into one consistent VestingStream format – same field names, same units, same structure, regardless of protocol.
Four clean endpoints that return structured JSON instantly from our persistent index. Interactive Swagger docs, full OpenAPI 3.1 spec, and standard Bearer auth – exactly what developers and integrations expect.
Published as an MCP server so AI agents – Claude, GPT, LangChain, CrewAI – can call our API as a native tool with zero custom integration code. One config block and your agent understands vesting.

}Use cases
Give your agent real-time vesting intelligence. Ask "when does my next unlock happen?" or "how much have I claimed this year?" – answered instantly from structured data.
Show users their complete vesting picture without building protocol-specific integrations for each chain. One API call replaces five.
Enrich your on-chain analytics with structured vesting data. Track team and investor unlock schedules, historical claims, and token release patterns.
Monitor vesting obligations across a portfolio. Flag upcoming unlocks, track claimed amounts, and generate structured reports for investors or regulators.
Build vesting-aware features into your protocol – show users their locked/claimable balances without reinventing the indexing layer.
Give your team and investors a transparent view of the vesting schedule. No custom dashboard needed – your data is already indexed.
Add Vestream to any AI agent in seconds. Our MCP server exposes tools for wallet vestings, upcoming unlocks, token unlocks and stream details that agents call natively without any custom glue code.
