# Rate limits For designers and integrators. Every authenticated request counts toward 500 per minute per API key (per user for signed-in dashboard sessions). Operations that create quotes, uploads and orders, or move money, also count toward 60 per minute. Public sign-up, catalog and shipping endpoints are limited per IP address. Responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`; past a limit the answer is 429 `rate_limited` with a `Retry-After` header. ## The limits Limits are counted in fixed windows. Each operation lists the limits it counts toward in `x-ratelimit` (`limit` requests per `window_seconds`, `per` API key or user, or per IP address); these are the defaults. | Applies to | Limit | Counted per | | --- | --- | --- | | Every authenticated request | 500 per minute | API key, or user for dashboard sessions | | Creating quotes, uploads and orders, cancelling orders, top-ups, card setup and withdrawals (on top of the above) | 60 per minute | API key, or user | | Integrator sign-up (`create_integrator_account`) | 10 per hour | IP address | | Resending the confirmation email (`resend_integrator_confirmation`) | 5 per hour | IP address | | Catalog and shipping reads (materials, categories, shipping rates and quotes) | 120 per minute | IP address | `get_health` and the OpenAPI document are not limited. Every limited response carries `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` (Unix seconds) for the limit closest to being reached. Past a limit the API answers 429 with code `rate_limited`, a `Retry-After` header in seconds, and `details` with `limit`, `window_seconds`, `reset_at` and `retry_after_seconds`. A refused request does not count. A request replayed with the same `Idempotency-Key` counts like any other request. ## Quotes, uploads, orders and payments These operations start slicing, create files or move money, so they also count toward a tighter limit per API key (or signed-in user). Each request still counts toward the general limit too. - [POST Quote a model file `/v2/quotes`](https://public-api.dapi.digital/docs/reference/quotes.md#create_quote) - [POST Create an order `/v2/orders`](https://public-api.dapi.digital/docs/reference/orders.md#create_order) - [POST Cancel an order `/v2/orders/{id}/cancel`](https://public-api.dapi.digital/docs/reference/orders.md#cancel_order) - [POST Order prints of your quotes `/v2/integrator/orders`](https://public-api.dapi.digital/docs/reference/integrator-orders.md#create_integrator_order) - [POST Cancel an order `/v2/integrator/orders/{id}/cancel`](https://public-api.dapi.digital/docs/reference/integrator-orders.md#cancel_integrator_order) - [POST Buy stock batches `/v2/stock-purchases`](https://public-api.dapi.digital/docs/reference/stocks.md#create_stock_purchase) - [POST Start adding a card `/v2/cards/setup-sessions`](https://public-api.dapi.digital/docs/reference/wallet.md#start_card_setup) - [POST Top up your wallet `/v2/top-ups`](https://public-api.dapi.digital/docs/reference/wallet.md#start_top_up) - [POST Request a withdrawal `/v2/withdrawals`](https://public-api.dapi.digital/docs/reference/wallet.md#create_withdrawal) - [POST Start a file upload `/v2/uploads`](https://public-api.dapi.digital/docs/reference/uploads.md#create_upload) ## Public endpoints Endpoints that need no key are limited per IP address: - [POST Sign up as an integrator `10 per hour`](https://public-api.dapi.digital/docs/reference/integrator-onboarding.md#create_integrator_account) - [POST Resend the confirmation email `5 per hour`](https://public-api.dapi.digital/docs/reference/integrator-onboarding.md#resend_integrator_confirmation) - [GET Get the shipping rate card `120 per minute`](https://public-api.dapi.digital/docs/reference/shipping.md#get_shipping_rates) - [GET Get a shipping price `120 per minute`](https://public-api.dapi.digital/docs/reference/shipping.md#get_shipping_quote) - [GET List catalog materials `120 per minute`](https://public-api.dapi.digital/docs/reference/materials.md#list_materials) - [GET Get a catalog material `120 per minute`](https://public-api.dapi.digital/docs/reference/materials.md#get_material) - [GET List product categories `120 per minute`](https://public-api.dapi.digital/docs/reference/categories.md#list_categories) - [GET Get a product category `120 per minute`](https://public-api.dapi.digital/docs/reference/categories.md#get_category) ## Handling a 429 Watch `X-RateLimit-Remaining` and slow down before it reaches 0. When a request is refused, wait for the number of seconds in `Retry-After`, then send it again. Retry a write with the same `Idempotency-Key`, so it never runs twice. **Retry after a 429 (Node.js)** ```javascript async function callWithRetry(url, init, attempts = 5) { for (let attempt = 1; ; attempt++) { const res = await fetch(url, init); if (res.status !== 429 || attempt === attempts) return res; // Retry-After is in seconds; wait at least that long. const seconds = Number(res.headers.get('retry-after') ?? 1); await new Promise((resolve) => setTimeout(resolve, seconds * 1000)); } } ``` **Retry after a 429 (Python)** ```python import time import requests def call_with_retry(method, url, attempts=5, **kwargs): for attempt in range(1, attempts + 1): res = requests.request(method, url, **kwargs) if res.status_code != 429 or attempt == attempts: return res # Retry-After is in seconds; wait at least that long. time.sleep(int(res.headers.get("Retry-After", "1"))) ``` **A 429 response body** ```json { "status_code": 429, "error": "Too Many Requests", "code": "rate_limited", "message": "Too many requests with this API key: the limit is 500 per minute. Retry after 42 seconds (at 2026-10-22T10:01:00.000Z).", "details": { "limit": 500, "window_seconds": 60, "reset_at": "2026-10-22T10:01:00.000Z", "retry_after_seconds": 42, "policy": "per_credential", "request_id": "req_6Yb2kQe0VxLr4TnPz8sWa1Mc" } } ``` --- 3DAPI API Docs.
