The Era API is in public preview, with docs at /docs/era-api
Read and manage your Era accounts, transactions, categories, tags and rules over REST with an API key. The reference and a public OpenAPI document are published.
The reference at /docs/era-api covers accounts and balances, transactions, categories, tags and automation rules, including previewing, enabling and disabling a rule. Reads need the banking:read scope and writes need banking:write. A write changes only what Era keeps: it can't move money, and nothing at your bank changes. The API serves its own OpenAPI document for the public operations at /api/openapi/public.json, with no key required, so you can generate a client from the contract. The API is in public preview, so an endpoint, a field or how a call behaves can still change, and this changelog records what does. Create a key from the API keys page in your Era account.
