Three ways in: REST, the MCP server, or the TypeScript SDK. Same data, same provenance contract everywhere.

# no key needed for coverage

$ curl https://api.binding.law/v1/law/coverage

# with a key: point-in-time statute text

$ curl "https://api.binding.law/v1/law/lookup?jurisdiction=fl&citation=768.28&asOf=2019-03-01" \

-H "Authorization: Bearer lf_live_..."

REST API

Quickstart

Auth, pagination, the provenance envelope, and the explicit-miss contract. Everything is JSON over HTTPS.

API reference →

MCP server

For agents

https://mcp.binding.law — streamable HTTP with an Authorization: Bearer header. Narrow tools, structured misses, citations your agent can hand to a human.

MCP quickstart →

TypeScript SDK

Typed end to end

npm i @jubal/binding-sdk — typed responses including the provenance envelope and miss discriminated union.
