Frequently asked questions

Meridian charges per token with no monthly minimums, no seat fees, and no hidden markups. You pay only for what you consume across any model. Full rate-card transparency is available on the /pricing page — every model, every context window, every token price listed upfront.

Yes. Meridian exposes a drop-in OpenAI-compatible API. Swap your base URL to https://api.meridian.sh/v1 and your existing SDK code — Python, Node, curl — works without modification. We support /chat/completions, /completions, /embeddings, and /models endpoints with identical request/response schemas.

Free-tier users get 60 requests per minute. Pay-as-you-go accounts start at 600 RPM and scale automatically with spend history. Enterprise contracts include guaranteed throughput SLAs. All limits are per-API-key and return standard 429 responses with Retry-After headers when hit.

Streaming (SSE) is supported on every model. Function calling / tool use follows the OpenAI tools schema exactly. Vision-capable models accept base64 image inputs via the standard content array format. JSON mode, seed, temperature, top_p, and stop sequences all work as expected.

Every new account receives $5.00 in free credits automatically on sign-up. No credit card required. Credits expire after 14 days. Once exhausted or expired, you can add a payment method and switch to pay-as-you-go instantly — no downtime, same API key.

Unused prepaid balance is refundable within 30 days of purchase. Consumption-based charges are non-refundable because compute has already been provisioned and consumed. Contact billing@meridian.sh and we process eligible refunds within 3 business days.

Go to Dashboard → Settings → Account → Delete Account. This permanently removes all API keys, usage history, and personal data. Deletion is irreversible and completes within 24 hours. For data export before deletion, use the Export Data button on the same page.

Yes. In Dashboard → API Keys, click Rotate next to any key. The old key remains valid for 24 hours so you can update production workloads without downtime. After the grace window, the old key is permanently revoked. You can maintain up to 5 active keys simultaneously.

BYOK is not currently available. We evaluated it extensively and found that key custody fragmentation creates latency regressions and complicates our abuse-prevention pipeline. We may revisit this for enterprise contracts in the future. For now, all inference runs through Meridian-provisioned capacity.

Email support@meridian.sh for account and billing issues — median first-response under 2 hours during business days. For real-time help, join our Discord at meridian.sh/discord. Enterprise customers receive a dedicated Slack channel. Status page: status.meridian.sh.
