Agentic workflows that never break
Fix bad requests on the fly so your app have no downtime.
Your AI agents keep failing for errors you could prevent
Deprecated / unsupported model
The model you're calling has been retired by the provider. Requests fail until you switch to a supported one.
Malformed parameter
You're sending a parameter the model doesn't accept, like max_tokens instead of max_completion_tokens. Each provider has its own naming.
Malformed message structure
The conversation format doesn't match what the provider expects. Missing fields, wrong roles, or thinking content not included in the response.
Malformed tool schemas
Your tool definitions use schema fields the provider doesn't support, like additionalProperties on Google's API.
Context length exceeded
Your prompt plus the requested output is longer than the model's context window. Something needs to be trimmed.
Rate limit / Insufficient balance
Your API key has hit its usage cap or run out of credits. The provider rejects every request until the limit resets or you top up.
Manifest automatically fixes your requests in real-time
Manifest inspects each request for failure signals before it breaks your app.
Manifest fixes the request on the fly before sending it to the model.
