Frequently Asked Questions

Like OpenRouter, BazaarLink provides a unified OpenAI-compatible API. It also offers Taiwan-local payment methods and electronic uniform invoices, Chinese-language support, and programmatic API key registration for AI agents. Model availability, pricing, and capabilities may change over time, so review the model catalog before integrating.

In most cases, you only need to change the base_url to https://bazaarlink.ai/api/v1, replace your API key with a BazaarLink API key, and confirm the full model ID in the model catalog. Before going live, test streaming, tool calling, and error handling because capabilities and parameters can vary between models.

If your company needs a Taiwan tax ID and electronic uniform invoice, choose a TWD payment method that is explicitly marked as invoice-eligible on the add-funds page, and complete the invoice details before paying. Different payment methods provide different documents, so whether a Taiwan invoice is issued depends on the information shown at checkout.

BazaarLink supports an OpenAI-compatible API and also provides an Anthropic Messages API. SDKs and tools that allow a custom API key and compatible endpoint can generally connect to BazaarLink. The exact configuration fields and supported features still depend on the tool version and should be verified against the BazaarLink documentation.

BazaarLink is designed for developers and teams that need access to multiple model providers through one API, Taiwan-local business expense and invoicing options, Chinese-language support, programmatic API key registration for AI agents, or public Probe data for evaluating API quality.

Model inference is billed with zero markup, using the input, output, or other billing units published on each model page. Platform fees are charged when funds are added, and some payment methods may also include a fixed processing fee, exchange-rate costs, or business tax. Always refer to the current amounts shown on the model page and payment confirmation page.

A USD credit-card payment through Stripe provides a Stripe payment receipt. It is not the same as a Taiwan electronic uniform invoice issued through an eligible BazaarLink TWD payment method. If your company needs a Taiwan tax ID and invoice for reimbursement or accounting, choose a payment method marked as invoice-eligible at checkout.

You can register and create an API key without adding a credit card first, then use the free models or auto:free routes available at that time. Free models, quotas, and usage limits may change dynamically, so refer to the free API page for current availability.

If your account has an available balance, requests can continue at the normal paid rates after the free quota is exhausted. If there is no available balance, wait for the quota to reset or add funds first. Free quotas and reset rules are configured dynamically, so this FAQ does not promise a fixed amount.

The public API includes OpenAI-compatible Chat Completions, Responses, Embeddings, image, video, and audio features, as well as the Anthropic Messages API. Supported input formats and features vary by model, so check both the API documentation and model catalog.

Use the full model ID returned by /api/v1/models or shown in the model catalog. Each model page lists its current pricing, context window, and supported capabilities. Unrecognized model IDs are rejected, so do not guess a name or rely on an outdated identifier.

Rate limits depend on the current settings for the account, plan, and model, so they cannot be represented by one fixed requests-per-minute value. Check your API key and usage information for the current status. When a limit is exceeded, the API returns HTTP 429; clients should retry according to Retry-After or an appropriate backoff strategy.

For ordinary successful requests, BazaarLink primarily retains billing and operational data such as the model, token usage, timestamp, and cost. Full prompts and responses are not stored as standard product records. Limited or truncated information may be retained for error diagnosis or abuse investigations. You should also review the data policies of the upstream model provider.

BazaarLink API keys are stored as irreversible hashes, while BYOK credentials for upstream providers are stored in encrypted form. Data in transit is protected with TLS. Keys can be revoked and safely rotated by creating and deploying a new key, verifying the deployment, and then revoking the old key.

When fallback routing is available, a timeout, rate limit, or certain upstream errors from the primary provider can trigger an attempt through the next configured provider or model. If every upstream route fails, the API returns an actionable error. Clients should still implement timeouts, retries, and graceful fallback strategies.

You can create multiple API keys and manage each key's spending limit and enabled status separately. To rotate a key with less risk of service interruption, deploy and verify the new key before revoking the old one. Never store a complete API key in source code or public records.

HTTP 402 usually indicates a balance, credit, or budget restriction. HTTP 429 indicates a rate limit. HTTP 502 indicates that an upstream request failed. HTTP 503 indicates that no route is currently available or that the service is temporarily unavailable. Record the request ID, then add funds, retry with backoff, switch models, or contact support as appropriate for the error.

Contact the team through the support page or at support@bazaarlink.ai. When reporting an API issue, include the time of the incident, request ID, model ID, HTTP status code, and any error details that are safe to share. Do not include a complete API key, prompt, or other sensitive information.
