Connect brokerage accounts to your app for live positions and trading. ## Rate limiting Two limits apply to requests signed with your `clientId`. The stricter one wins, and exceeding either returns `429 Too Many Requests`. - **Customer-level** — 250 requests/minute by default, scoped to your `clientId` and applied across all endpoints. Reported in `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`. - **Account-level** — 10 requests/minute per account, scoped to (`clientId`, `accountId`). All covered operations for one account draw on the same bucket — reading balances and reading positions share it — and enforcement does not depend on the HTTP method, so updating an account consumes the same bucket as reading it. Only enforced for Personal users, and only for integrations it has been rolled out to — it is not yet in force for every Personal integration. It also does not apply on every operation that documents a 429 below. Where it applies it is reported in `X-RateLimit-Account-Limit`, `X-RateLimit-Account-Remaining` and `X-RateLimit-Account-Reset`. Do not read the absence of those headers as proof the limit is off — some configurations omit the rate limit headers while still enforcing the limit, so header absence tells you nothing about your allowance. On a 429, `X-RateLimit-Remaining: 0` means you hit the customer-level limit and `X-RateLimit-Account-Remaining: 0` means the account-level one. Wait for the corresponding `*-Reset` value (seconds) before retrying, or fall back to exponential backoff with jitter. Not every 429 is explained by those headers. A separate per-authenticated-user limit, reported in no `X-RateLimit-*` header, covers OAuth-authenticated requests and signed requests in configurations where the customer-level limit is not in effect — on the operations that use the default throttles. A few operations override those and are governed by the customer-level limit alone. The two do not stack: a signed request governed by the customer-level limit above is not additionally subject to the per-user one. If a 429 arrives with no header at zero — or with no `X-RateLimit-*` headers at all — honour `Retry-After` and back off. Treat the remaining counts as a hint, not a guarantee that the next request will succeed. Because the customer-level limit applies everywhere, any signed request can return 429. **OAuth-authenticated requests are an exception.** They are not subject to the customer-level limit and do not receive `X-RateLimit-Limit`, `X-RateLimit-Remaining` or `X-RateLimit-Reset` — do not wait on those headers or design around a customer-level allowance on this path. The account-level limit still applies to them on the account-data endpoints above, reported in the `X-RateLimit-Account-*` headers. On operations using the default throttles the per-user limit above applies to them as well, so an OAuth request can be rejected while the account headers still show capacity; on the few operations that override those throttles, OAuth callers have no per-user ceiling at all. Drive retries from `Retry-After` and exponential backoff with jitter rather than from the headers. See https://docs.snaptrade.com/docs/ratelimiting.

RevKeen is a fintech-grade API for payments, subscriptions, invoices, and billing. The canonical production MCP server is available at `https://mcp.revkeen.com/mcp`. **API Version:** `2026-05-01` — Pin with the `RevKeen-Version` header. **Quick Links:** [Full Documentation](https://docs.revkeen.com) | [Authentication](https://docs.revkeen.com/authentication) | [OAuth](https://docs.revkeen.com/oauth) | [SDKs](https://docs.revkeen.com/sdks) | [Webhooks](#webhooks) | [MCP Guide](https://docs.revkeen.com/mcp) ## Authentication Two authentication methods are supported: ### API Keys (recommended for server-to-server REST API integrations) Send your API key in the `x-api-key` header. Get keys from the [Dashboard](https://app.revkeen.com/settings/api-keys). Use `rk_sandbox_*` for test mode and `rk_live_*` for production. ### OAuth 2.1 (recommended for MCP and third-party integrations) Use OAuth 2.1 with PKCE for authorization code flow or client credentials for server-to-server. Tokens are sent via `Authorization: Bearer rk_oauth_*`. See the [OAuth guide](https://docs.revkeen.com/oauth) for setup. - **Authorization Code + PKCE** — user-facing integrations, MCP hosts - **Client Credentials** — server-to-server, automated workflows - **Dynamic Client Registration** — MCP hosts that auto-register ## MCP Integration RevKeen's canonical production MCP server is `https://mcp.revkeen.com/mcp` using Streamable HTTP and OAuth 2.1 bearer tokens. - **Customer launch surface** — read-first customer v1 tools with least-privilege scopes - **Host setup guide** — see the [MCP guide](https://docs.revkeen.com/mcp) for ChatGPT, Claude, and compatible MCP hosts ## API Key Scopes Scopes follow `{resource}:{action}` format (e.g., `invoices:read`, `customers:*`).
