BlazingFast Customer API
Automate account billing, VPS and dedicated servers, DNS and Website Protection, TCP Proxy, domains, SSH keys, firewall policies and storage. Use an official SDK for HMAC-signed requests, or a bearer-mode API key. Generic OpenAPI-generated clients do not implement BlazingFast HMAC signing automatically. Pagination is endpoint-specific: follow the documented page/limit, cursor/next_cursor or offset/next_offset model. limit is the canonical page-size parameter; page_size and pageSize are deprecated compatibility aliases only where documented. Begin by reading the resource, confirm changes, and inspect the result or returned task. Draft order creation does not charge the account. Atomic deployment is the documented exception: order + full final order amount paid from account balance + queued provisioning. Payment is not successful provisioning; accepted is not completed. Access depends on key scopes and account permissions.
Deployments
Configure and quote a regional deployment, then authorize the full final order amount from account balance and queue provisioning. A quote is read-only; deployment is a financial write.
Authentication
SignedAuth
SignedAuth is represented by x-api-key for discovery only. Generic OpenAPI-generated clients do not automatically implement BlazingFast HMAC signing. Use BearerAuth with a bearer-mode credential or an official SDK, unless you implement the signing algorithm manually. Signed-key mode requires all five headers. SDKs send x-api-key, x-ts (Unix seconds), x-nonce, x-content-sha256 (Base64 SHA-256 of the exact body), and x-signature (Base64 HMAC-SHA256). Custom signing is explained in the API authentication guide. Every HTTP attempt needs a fresh timestamp and nonce; an action retry retains its original idempotency key and payload. Key expiry, IP restrictions, account permissions and scopes still apply.
BearerAuth
Alternative mode for integrations that prefer Authorization: Bearer <prefix.secret>. Key status, expiry, scope checks, IP policy, and rate limits still apply.
Endpoints
/v1/deploy/{region}/{productCode}/{variantCode}
Deploy product variant from wallet
Operation ID: productVariantDeploy
One call validates a public VPS, managed dedicated, TCP proxy, Website Protection or software-license variant, creates its order/invoice, charges the full final order amount to the account balance and queues normal provisioning. Insufficient funds returns HTTP 402 insufficient_credit with no committed order/payment. Uses account billing currency and authoritative prices including tax, setup and add-ons. max_total is an optional decimal-string spending ceiling in that currency. Requires both scopes. Idempotency-Key is required; reuse identical arguments after interruption. Never charges a card or tops up the wallet. Acceptance is not a ready server: inspect returned serviceIds. Dedicated admin approvals, inventory and license rollout gates still apply. Domains/free products are not supported by this convenience endpoint; legacy unpaid checkout/payment remain unchanged.
Parameters
region- Region code, for example nl or pt.
productCode- Catalog product_code: vps, dedicated, tcp-proxy, waf or license.
variantCode- Exact public catalog variant_code/SKU, for example 2G or PTV4-1.
Idempotency-Key- Stable retry key, 8–128 characters. Never replace it after an uncertain response.
x-client-request-id- Optional client correlation label, 1–120 letters/digits/dots/underscores/colons/hyphens. Logged alongside the server request ID; never an idempotency key.
x-bf-response-format- Opt into the canonical Operation receipt for this tracked write. Requires canonical_operation_responses enabled. Omit for the legacy response. Retried requests may replay their initial response format; use its operation_id or operation.id to poll.
x-ts- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Unix timestamp in seconds; refresh it for every HTTP attempt. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.
x-nonce- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Fresh nonce for every HTTP attempt; never reuse it when retrying. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.
x-content-sha256- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Base64 SHA-256 of the exact transmitted body bytes; hash the empty body for bodyless requests. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.
x-signature- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Base64 HMAC-SHA256 signature produced by the documented signing algorithm. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.

Fully paid order with asynchronous provisioning queued.

Create a bearer-mode key in Settings → API with the scopes shown above. Set BF_API_BEARER privately to its full prefix.secret value. These are request snippets, not complete applications. This page does not send requests.
Bash · cURL 7.87+. Supply URL-encoded path values; query values are encoded by cURL.
BF_PATH_REGION — path parameter region (required). Region code, for example nl or pt.
BF_PATH_PRODUCT_CODE — path parameter productCode (required). Catalog product_code: vps, dedicated, tcp-proxy, waf or license.
BF_PATH_VARIANT_CODE — path parameter variantCode (required). Exact public catalog variant_code/SKU, for example 2G or PTV4-1.
BF_REQUEST_KEY — header parameter Idempotency-Key (required). Stable retry key, 8–128 characters. Never replace it after an uncertain response.
BF_HEADER_X_CLIENT_REQUEST_ID — header parameter x-client-request-id (optional). Optional client correlation label, 1–120 letters/digits/dots/underscores/colons/hyphens. Logged alongside the server request ID; never an idempotency key.
BF_HEADER_X_BF_RESPONSE_FORMAT — header parameter x-bf-response-format (optional). Opt into the canonical Operation receipt for this tracked write. Requires canonical_operation_responses enabled. Omit for the legacy response. Retried requests may replay their initial response format; use its operation_id or operation.id to poll.
Replace example body values with your configuration. Discover compatible profile IDs and account-owned key IDs before use.
Review the target and payload before running. For a payment, check the invoice and outstanding amount first. Reuse BF_REQUEST_KEY for retries of the same operation; check status after an interrupted request.
Check the HTTP status and handle errors in your application. Examples validate TLS, have a 30-second request limit, and never automatically retry or follow redirects. Run cURL on a private workstation: expanded tokens appear in process arguments, so disable shell tracing and command logging. Do not log passwords or share credential responses.

/v1/deploy/{region}/{productCode}/{variantCode}/quote
Quote a configured product by code
Operation ID: productVariantQuote
Accepts exactly the same simple or legacy body as deployment. Uses authoritative account currency, configuration, tax and add-on prices. Returns a price breakdown and reserved=false; creates no order, invoice, reservation or payment. No Idempotency-Key required. The quote object adds an opaque diagnostic id, guaranteed=false, currency, final total, breakdown, pricing_revision and recommended_max_total. Pass recommended_max_total as max_total to deployment. The revision fingerprints this priced cart; it is not a price lock, reservation or redeemable quote. A quote is optional and is not a stock or price guarantee.
Parameters
region- Eligible region, for example nl or pt. A single region is required.
productCode- Product family.
variantCode- Exact case-sensitive public SKU, for example 2G or PTV4-1. Never an internal inventory ID.
x-client-request-id- Optional client correlation label, 1–120 letters/digits/dots/underscores/colons/hyphens. Logged alongside the server request ID; never an idempotency key.
x-ts- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Unix timestamp in seconds; refresh it for every HTTP attempt. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.
x-nonce- Required when using SignedAuth with x-api-key; omitted for BearerAuth. Fresh nonce for every HTTP attempt; never reuse it when retrying. Generic OpenAPI clients do not compute HMAC signatures; use an official SDK or implement signing manually.

Errors and safe retries
Use HTTP status and error.code for decisions. The canonical envelope contains error.message, error.request_id and error.field_errors. Flat code, message, request_id, field_errors, details and status fields are legacy compatibility fields and may still appear; new integrations should read the nested error.

"request_id": "00000000-0000-4000-8000-000000000001",
"field_errors": []
}
}Error code reference
Server failures and interrupted connections
Generic API server failures intentionally omit internal error codes and provider details and use the same nested envelope with service_unavailable. An edge/network failure can also return non-JSON or no response at all.
json
{
"ok": false,
"error": {
"code": "service_unavailable",
"message": "The service is temporarily unavailable.",
"request_id": "00000000-0000-4000-8000-000000000001",
"field_errors": []
}
}Read-only GET requests can be retried with bounded backoff and jitter. SDKs perform limited retries for selected transient read failures; they do not automatically retry writes. A timeout or 5xx on a write does not prove it failed: check the resource, invoice or task before retrying. Where supported, reuse the same Idempotency-Key and identical request. Do not create a new operation key just because the response was lost.
For 429, honor the HTTP Retry-After header. SDK timeout, network_error and response_too_large codes describe client-side failures, not API error responses. For persistent errors, send support the request ID, HTTP status, method, endpoint and UTC time—never API secrets or passwords.
See error handling in PHP, Node.js, Python and GoThis reference is generated from the current OpenAPI schema and documents 182 public operations. Each operation has a stable operationId and shows its method, path, parameters, required permissions and response models. cURL is selected by default; switch to Node.js, PHP, Python or Go for native HTTP examples. Download the OpenAPI JSON for client generation.
Use the integration guide for SDK/CLI 0.1.17 installation, authentication, pagination, retries, idempotency, webhooks and workflows. Generic OpenAPI clients do not automatically implement HMAC signing; use Bearer authentication or an official SDK unless you implement signing yourself.
Current purchase and operation workflows
SDK/CLI 0.1.17 supports contract 2026-10-07.1. Read GET /v1/version and GET /v1/capabilities, then discover product purchase policies and requirements before configuring a purchase. A quote is optional: discovery can lead directly to an authorized deployment. Quotes do not reserve stock or lock prices; send an authorized max_total ceiling for the full final order amount.
Draft order creation does not charge the account. Atomic deployment is the documented exception: it combines order creation, payment of the full final order amount from account balance and queued provisioning. Paid is not ready; accepted is not completed. Service lifecycle status is separate from runtime power state.
Supported tracked deployment, VPS and dedicated writes can return a canonical operation receipt and be recovered using their original idempotency key. This does not extend recovery to every write or historical request. See HTTP, SDK, CLI and MCP examples. DNSSEC uses its separate endpoint and state contract.
Pagination is endpoint-specific. Follow each endpoint's page/limit, cursor/next_cursor or offset/next_offset contract. limit is the canonical page-size request parameter; page_size and pageSize are deprecated compatibility aliases only where documented.
For service lists, ownership and filters are applied server-side before pagination. GET /v1/services defaults to active and suspended. group_by=type groups only the current page; GET /v1/services/grouped returns the complete inventory under its documented status/type filters, with its legacy active-only default. Pass status explicitly for this compatibility endpoint; prefer /v1/services?statuses=active,suspended&group_by=type for new automation.
API errors use the canonical nested error.code, error.message, error.request_id and error.field_errors structure. Flat error fields remain legacy compatibility fields. Most CLI lifecycle --request-key flags are optional; DNSSEC enable/disable require an explicit key. Preserve generated keys for retries. Examples describe requests and responses; this page does not send API requests.
