# Venice errors & retries

Most Venice errors are `{ "error": "<message>" }`, but several paths add structure. Knowing which shape you got tells you how to react.

## Error body shapes

### 1. `StandardError` - simple message

The default for 4xx/5xx.

```json
{ "error": "Authentication failed" }
```

### 2. `DetailedError` - schema validation failure (`400`)

When a request fails Venice's own schema, `details` is a nested tree (`_errors` recursively keyed by field) and `issues` is the flat issue list. Some image, video and upstream failures instead return `details` as a plain string, so check its type before walking it.

```json
{
  "error": "Invalid request parameters",
  "details": {
    "_errors": [],
    "type": { "_errors": ["Invalid enum value. Expected 'asr' | 'decision' | … , received 'bogus'", "Invalid enum value. Expected 'all' | 'code', received 'bogus'"] }
  },
  "issues": [
    { "code": "invalid_union", "unionErrors": [ … ], "path": ["type"], "message": "Invalid input" }
  ]
}
```

(That is the live response to `GET /models?type=bogus`.)

Many `400`s are plain `StandardError` - handle both. Render `details` / `issues`; don't retry.

### 3. OpenAI-style context overflow (`400`, chat)

```json
{
  "error": {
    "message": "Your request exceeds the model's maximum context. Please reduce your prompt or completion length.",
    "type": "invalid_request_error",
    "param": "messages",
    "code": "context_length_exceeded"
  }
}
```

Note `error` is an **object** here, so OpenAI SDKs can detect it. `message` is the provider's wording when Venice can extract it, otherwise the text above - match on `code`, not `message`. Trim the prompt or lower `max_completion_tokens`.

### 4. Upstream provider rejection (`400`)

When the request passed Venice's schema but the model provider rejected it, Venice returns the provider's message, plus a `request_id` on routes that track one (chat, for example; `/decisions` omits it):

```json
{ "error": "<provider's validation message>", "request_id": "…" }
```

FastAPI-style validation errors (e.g. from the TypeSafe provider behind `POST /decisions`, which answers `422`) are surfaced as `400` with up to five `field.path: message` items joined by `; `. If Venice can't extract a message you get `"Invalid request parameters. For assistance, please reach out to support@venice.ai"`, followed by `" and reference request ID: <id>"` when there is one. These count against the lenient unsupported-feature budget on chat / responses (see [Error budget](#error-budget)). Fix the input; quote `request_id` to support.

### 5. `ContentViolationError` - `422` content policy

```json
{
  "error": "Your prompt violates the content policy of Venice.ai or the model provider",
  "suggested_prompt": "A cinematic instrumental track inspired by stormy weather and dramatic tension."
}
```

Returned by chat, responses, image edit and multi-edit, and audio generation. `/image/generate` does not use it (a blocked image comes back as a `200` with `x-venice-is-content-violation: true`), and video content-policy rejections arrive on `/video/retrieve` rather than on queue. `suggested_prompt` is only emitted by `/audio/queue` and `/audio/retrieve`; when present, retry once with it if the user consents. Other `422`s include `"Your input was blocked by content moderation."` and media-validation failures (image too large, bad aspect ratio, audio/video duration out of range, ASR unable to process the audio).

### 6. `ProviderContentPolicyError` - `422` on `/video/retrieve`

```json
{
  "error": {
    "message": "The selected model provider rejected this request due to its content policies. Credits have been refunded. Try using <model> instead.",
    "type": "provider_content_policy",
    "credits_refunded": true,
    "recommended_model": "<model id>"
  }
}
```

Check `credits_refunded`; optionally re-queue on `recommended_model`.

### 7. `PayloadTooLargeError` - `413`

```json
{ "code": "PAYLOAD_TOO_LARGE", "error": "File exceeds the maximum allowed size of 25 MB." }
```

### 8. x402 `402` bodies

A `402` comes in two forms. Both also set the `PAYMENT-REQUIRED` header. The no-credentials form is returned on every route that needs credentials, including Bearer-only routes (`/api_keys*`, `/billing/*`, `/characters*`), where its payment options don't apply.

**No credentials at all** - x402 v2 discovery (not `401`):

```json
{
  "x402Version": 2,
  "error": "Authentication required",
  "resource": { "url": "https://api.venice.ai/api/v1/chat/completions", "description": "Venice API", "mimeType": "application/json" },
  "accepts": [ { "scheme": "exact", "network": "eip155:8453", "…": "…" }, { "scheme": "exact", "network": "solana", "…": "…" } ],
  "extensions": { "sign-in-with-x": { "info": { "domain": "api.venice.ai", "statement": "Sign in to Venice AI", "…": "…" }, "supportedChains": [ … ] } },
  "authOptions": {
    "apiKey": { "header": "Authorization: Bearer YOUR_API_KEY", "getKey": "https://venice.ai/settings/api", "docs": "…" },
    "x402Wallet": { "header": "SIGN-IN-WITH-X", "legacyHeader": "X-Sign-In-With-X", "topUp": "POST /api/v1/x402/top-up", "docs": "…" }
  }
}
```

**Signed-in wallet below the $0.10 minimum balance** - discriminate on `code: "PAYMENT_REQUIRED"`:

```json
{
  "error": "Payment required",
  "code": "PAYMENT_REQUIRED",
  "reason": "insufficient_balance",
