OpenEvidence Common Errors

Overview

OpenEvidence provides AI-powered clinical decision support through evidence-based query answering with citation tracking. API integrations involve submitting clinical questions, retrieving evidence summaries, and managing citation references. Common errors include overly broad queries that exceed processing limits, citation-not-found errors when referenced studies are retracted, and timeouts on complex multi-condition queries that trigger deep literature analysis. The DeepConsult mode provides more thorough analysis but consumes 5x the rate limit quota and has a 90-second timeout. This reference covers authentication, query validation, and clinical-specific error patterns.

Error Handler

interface OpenEvidenceError {
  code: number;
  message: string;
  category: "auth" | "rate_limit" | "query" | "availability";
}

function classifyOpenEvidenceError(status: number, body: string): OpenEvidenceError {
  if (status === 401 || status === 403) {
    return { code: status, message: body, category: "auth" };
  }
  if (status === 429) {
    return { code: 429, message: "Rate limited", category: "rate_limit" };
  }
  if (status === 503) {
    return { code: 503, message: body, category: "availability" };
  }
  return { code: status, message: body, category: "query" };
}

Debugging Guide

Authentication Errors

OpenEvidence API keys are scoped per organization. A 401 means the key itself is invalid; a 403 means the key is valid but not authorized for the specified org ID. Verify both the OPENEVIDENCEAPIKEY and the org_id parameter match. Keys are rotated quarterly for compliance -- check expiration date.

Rate Limit Errors

Rate limits vary by plan tier. Standard plans allow 100 queries/hour; enterprise plans have higher limits. DeepConsult queries (longer analysis) consume 5x the rate limit quota of standard queries. Use Retry-After header and implement exponential backoff.

Validation Errors

Queries must be clinically relevant and specific. "What causes headaches?" is too broad -- narrow to "What is the first-line treatment for migraine with aura in adults?" Add population, intervention, or comparison to improve query specificity. Non-medical queries are rejected with 422. Citation references use DOI-based identifiers; retracted studies return 404 and should be re-queried for updated evidence.
