Request Logs - Codex-LB

Overview

The Request Logs API provides access to historical records of all proxy requests, including request metadata, status codes, token usage, costs, and errors. Use this API to debug issues, analyze usage patterns, and monitor system health.

All Request Logs endpoints require dashboard authentication via session cookie.

Filtering Examples

By Time Range

View requests from the last hour:

curl "https://your-instance.com/api/request-logs?since=2026-03-03T19:00:00Z&until=2026-03-03T20:00:00Z"

By Account

View all requests for a specific account:

curl "https://your-instance.com/api/request-logs?accountId=acc_123abc"

By Status

Find all failed requests:

curl "https://your-instance.com/api/request-logs?status=429&status=500&status=error"

By Model

Filter to Opus requests only:

curl "https://your-instance.com/api/request-logs?model=claude-opus-4-20250514"

By Model + Reasoning Effort

Find high reasoning effort Opus requests:

curl "https://your-instance.com/api/request-logs?modelOption=claude-opus-4-20250514:::high"

Search by Text

Search for specific error messages:

curl "https://your-instance.com/api/request-logs?search=overloaded"

Combined Filters

Find expensive failed Opus requests in the last 24 hours:

curl "https://your-instance.com/api/request-logs?model=claude-opus-4-20250514&status=error&since=2026-03-02T20:00:00Z&limit=100"

Pagination

The API uses offset-based pagination:

# First page (logs 0-49)
curl "https://your-instance.com/api/request-logs?limit=50&offset=0"

# Second page (logs 50-99)
curl "https://your-instance.com/api/request-logs?limit=50&offset=50"

# Third page (logs 100-149)
curl "https://your-instance.com/api/request-logs?limit=50&offset=100"

Check the has_more field to determine if additional pages exist:

if (response.has_more) {
  // Fetch next page with offset += limit
}

Status Codes

Common status values in logs:

Status	Description
`200`	Successful request
`400`	Bad request (client error)
`401`	Authentication failed
`403`	Forbidden (e.g., model not allowed, IP blocked)
`429`	Rate limit exceeded
`500`	Internal server error
`502`	Bad gateway (upstream API error)
`error`	Generic error (see error_code for details)

Error Codes

Common error_code values:

Error Code	Description
`overloaded_error`	Claude API is overloaded
`rate_limit_error`	Account quota exceeded
`invalid_request_error`	Malformed request
`authentication_error`	Invalid or expired credentials
`model_not_allowed`	API key doesn’t have access to this model
`ip_forbidden`	Client IP not in firewall allowlist

Token and Cost Tracking

Token Fields

tokens: Total tokens (input + output). Null for failed requests.
cached_input_tokens: Prompt cache hits. Reduces cost but still counted in usage.

Cost Calculation

Costs are estimated based on:

Model pricing (per 1M tokens)
Input/output token split
Cached token discount
Reasoning effort multiplier (if applicable)

The cost_usd field shows the calculated cost for the request. Sum this field to analyze spending patterns.

Use Cases

Debugging

Search for specific request IDs or error messages to diagnose issues.

Cost Analysis

Filter by model and time range to understand spending by model type.

Performance Monitoring

Track latency_ms across different models and accounts.

Usage Patterns

Identify peak usage times and model preferences.

Performance Considerations

Index Optimization

The following queries are optimized with database indexes:

Time range filtering (since, until)
Account ID lookups
Status filtering
Model filtering

Large Result Sets

For querying large date ranges:

Use smaller limit values (50-100)
Implement cursor-based pagination
Consider exporting data for offline analysis

Real-time Monitoring

For live dashboards, poll with a small time window:

# Last 5 minutes, poll every 30 seconds
curl "https://your-instance.com/api/request-logs?since=2026-03-03T19:55:00Z&limit=100"

Authentication

All request log endpoints require dashboard authentication via session cookie.

Common Patterns

Error Rate Dashboard

Calculate error percentage over the last hour:

const all = await fetch('/api/request-logs?since=' + oneHourAgo + '&limit=1000');
const errors = await fetch('/api/request-logs?since=' + oneHourAgo + '&status=error&status=429&status=500&limit=1000');

const errorRate = (errors.total / all.total) * 100;

Cost Per Model Report

Sum costs by model:

const models = ['claude-opus-4-20250514', 'claude-sonnet-4-20250514'];
const costs = {};

for (const model of models) {
  const logs = await fetchAllPages(`/api/request-logs?model=${model}&since=${startDate}`);
  costs[model] = logs.reduce((sum, log) => sum + (log.cost_usd || 0), 0);
}

Account Health Check

Find accounts with high error rates:

const accounts = await fetch('/api/request-logs/options').then(r => r.json());

for (const accountId of accounts.account_ids) {
  const total = await fetch(`/api/request-logs?accountId=${accountId}&limit=1`).then(r => r.json());
  const errors = await fetch(`/api/request-logs?accountId=${accountId}&status=error&limit=1`).then(r => r.json());
  
  const errorRate = (errors.total / total.total) * 100;
  if (errorRate > 10) {
    console.warn(`Account ${accountId} has ${errorRate.toFixed(1)}% error rate`);
  }
}
