The Portfobit Open API is for direct API clients, CI, scripts, service accounts, third-party agents, and developer integrations that work with crypto CEX portfolios.

​
Base URL

Use the production base URL for all REST API requests:
Endpoint paths in this reference are relative to the /api/v1 base path. For example, GET /accounts resolves to GET https://api.portfobit.com/api/v1/accounts. Use a scoped Portfobit Open API key to authenticate requests. See Authentication and scopes. Remote MCP uses its own OAuth resource. An MCP OAuth access token is not a public REST API credential and is rejected when sent directly to /api/v1/*.

​
Current capabilities

  • discover supported CEX connectors and service egress IPs;
  • connect and synchronize crypto CEX accounts, then read balances, positions, summaries, valuation history, and activity history;
  • request a bounded import when older or missing CEX activity history is needed;
  • manage portfolios and inspect their aggregated risk;
  • retrieve market quotes and bounded OHLCV candles from a connected CEX;
  • submit a support problem; and
  • with the explicitly enabled scopes, user confirmation, an Idempotency-Key, and a current trading OTP, place, cancel, or amend CEX orders and initiate an internal transfer within the same CEX account.
The API never supports withdrawals, transfers to an external address, cross-exchange transfers, P2P transfers, or raw exchange-parameter passthrough. It does not provide a WebSocket API.
Valuation history, activity history, explicit activity imports, and protected actions require an active Plus or Pro subscription. Valuation history contains daily NAV snapshots, not performance P&L or returns. See Plans, Features, and Limits for current quotas and retention behavior. The actual endpoint remains the authority for subscription, resource-ownership, provider-permission, OTP, and risk checks.
