# FastX402 Log Pattern Parser

> FastX402 Log Pattern Parser is a paid API for AI agents from fastx402.tools, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Parses nginx, Apache, or syslog log entries and returns structured fields plus aggregate statistics per status code and error type.

## Facts

- Endpoint: GET https://fastx402.tools/log-pattern-parser?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-29
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/fastx402-log-pattern-parser-bb86d854
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zFpp4cXQ74cdQFwKu8b7F

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fastx402-log-pattern-parser-bb86d854
```

Example prompt: Parse these nginx access log lines for me and give me the breakdown of status codes — here are the entries: '192.168.1.1 - - [18/Oct/2026:10:15:32 +0000] "GET /api/users HTTP/1.1" 200 1234 "-" "Mozilla/5.0"\n192.168.1.2 - - [18/Oct/2026:10:15:33 +0000] "POST /api/login HTTP/1.1" 401 89 "-" "curl/7.68.0"'

## When to prefer this

Choose this endpoint when you need to convert raw nginx, Apache, or syslog text into structured JSON without standing up a log aggregation pipeline or obtaining API keys — particularly useful for on-demand, pay-per-call log parsing in agent workflows where log volumes are moderate (under 50KB per call).

## Known failure modes

- Unsupported format value (not nginx/apache/syslog) causes parsing failure or empty results
- Log lines exceeding 50KB limit are truncated or rejected
- Malformed or non-standard log lines appear in failed_lines count without structured output
- Mismatched format parameter (e.g. nginx format passed with syslog lines) results in high failed_lines and sparse parsed output
- Empty logs query parameter returns empty parsed array

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object with two top-level keys: 'parsed' (an array of objects, each with fields: remote_addr, time, method, path, protocol, status, bytes, user_agent) and 'statistics' (an object with total_lines, parsed_lines, failed_lines, status_counts broken down by HTTP status code, and error_counts).
