Exa Common Errors

Prerequisites

A bounded non-sensitive reproduction, environment/version, expected behavior, and redaction rule for diagnostics.

Output

A classified Exa failure with redacted evidence and a verified bounded remediation or escalation.

Error Handling

| Condition | Safe response | |---|---| | Authentication fails | Verify the scoped secret reference/environment; revoke/rotate if exposure is suspected. | | Result is unexpected | Inspect supported sources, date, options, and citations with a sanitized query before changing policy. | | Throttling occurs | Apply documented backoff and reduce concurrency; do not bulk retry. | | Request includes sensitive data | Stop, sanitize/use an approved path, and follow exposure policy. |

Examples

For a failing request, record correlation ID, environment, status class, latency, and sanitized request category, then validate credentials and options against a non-sensitive fixture. Escalate with redacted evidence rather than full query/result content.

Overview

Quick reference for Exa API errors by HTTP status code and error tag. All error responses include a requestId field — include it when contacting Exa support at hello@exa.ai.

Error Reference

400 — Bad Request

| Error Tag | Cause | Solution | |-----------|-------|----------| | INVALID_REQUEST_BODY | Malformed JSON or missing required fields | Validate JSON structure and required query field | | INVALID_REQUEST | Conflicting parameters | Remove contradictory options (e.g., date filters with company category) | | INVALID_URLS | Malformed URLs in getContents | Ensure URLs have https:// protocol | | INVALID_NUM_RESULTS | numResults > 100 with highlights | Reduce to <= 100 or remove highlights | | INVALID_JSON_SCHEMA | Bad schema in summary.schema | Validate JSON schema syntax | | NUM_RESULTS_EXCEEDED | Exceeds plan limit | Check your plan's max results | | NO_CONTENT_FOUND | No content at provided URLs | Verify URLs are accessible |

401 — Unauthorized

# Verify your API key is set and valid
echo "Key set: ${EXA_API_KEY:+yes}"

# Test with curl
curl -s -o /dev/null -w "%{http_code}" \
  -X POST https://api.exa.ai/search \
  -H "x-api-key: $EXA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"test","numResults":1}'

Fix: Regenerate API key at dashboard.exa.ai.

402 — Payment Required

| Error Tag | Cause | Solution | |-----------|-------|----------| | NO_MORE_CREDITS | Account balance exhausted | Top up at dashboard.exa.ai | | API_KEY_BUDGET_EXCEEDED | Spending limit reached | Increase budget in API key settings |

403 — Forbidden

| Error Tag | Cause | Solution | |-----------|-------|----------| | ACCESS_DENIED | Feature not available on plan | Upgrade plan or contact Exa | | FEATURE_DISABLED | Endpoint not enabled | Check plan capabilities | | ROBOTS_FILTER_FAILED | URL blocked by robots.txt | Use a different URL | | PROHIBITED_CONTENT | Content blocked by moderation | Review query for policy violations |

429 — Rate Limited

// Default rate limit: 10 QPS (queries per second)
// Error response format: { "error": "rate limit exceeded" }

// Fix: implement exponential backoff
async function searchWithBackoff(exa: Exa, query: string, opts: any) {
  for (let attempt = 0; attempt < 5; attempt++) {
    try {
      return await exa.search(query, opts);
    } catch (err: any) {
      if (err.status !== 429) throw err;
      const delay = 1000 * Math.pow(2, attempt) + Math.random() * 500;
      console.log(`Rate limited. Waiting ${delay.toFixed(0)}ms...`);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error("Rate limit retries exhausted");
}

422 — Unprocessable Entity

| Error Tag | Cause | Solution | |-----------|-------|----------| | FETCH_DOCUMENT_ERROR | URL could not be crawled | Verify URL is accessible and not paywalled |

5xx — Server Errors

| Code | Tag | Action | |------|-----|--------| | 500 | DEFAULT_ERROR / INTERNAL_ERROR | Retry after 1-2 seconds | | 501 | UNABLE_TO_GENERATE_RESPONSE | Rephrase query (answer endpoint) | | 502 | Bad Gateway | Retry with delay | | 503 | Service Unavailable | Check status page, retry later |

Content Fetch Errors (per-URL status in getContents)

| Tag | Cause | Resolution | |-----|-------|-----------| | CRAWL_NOT_FOUND | Content unavailable at URL | Verify URL correctness | | CRAWL_TIMEOUT | Fetch timed out | Retry or increase livecrawlTimeout | | CRAWL_LIVECRAWL_TIMEOUT | Live crawl exceeded timeout | Set livecrawlTimeout: 15000 or use livecrawl: "fallback" | | SOURCE_NOT_AVAILABLE | Paywalled or blocked | Try cached content with livecrawl: "never" | | UNSUPPORTED_URL | Non-HTTP URL scheme | Use standard HTTPS URLs |

Quick Diagnostic Script

set -euo pipefail

echo "=== Exa Diagnostics ==="
echo "API Key: ${EXA_API_KEY:+SET (${#EXA_API_KEY} chars)}"

# Test basic connectivity
echo -n "API connectivity: "
HTTP_CODE=$(curl -s -o /tmp/exa-test.json -w "%{http_code}" \
  -X POST https://api.exa.ai/search \
  -H "x-api-key: $EXA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"connectivity test","numResults":1}')
echo "$HTTP_CODE"

if [ "$HTTP_CODE" != "200" ]; then
  echo "Error response:"
  cat /tmp/exa-test.json | python3 -m json.tool 2>/dev/null || cat /tmp/exa-test.json
fi
