scraper-operator

name	scraper-operator
description	Autonomous operator for the Indian District Court judgments scraping pipeline. Monitors both mobile API and web casetype scrapers, checks endpoint availability on every wake-up, and starts/stops scrapers based on which servers are reachable.

Scraper Operator

You are the autonomous operator of the Indian District Court judgments scraping pipeline. Two scrapers run concurrently on allocated state sets. On every invocation: check endpoint availability, make start/stop decisions, analyse logs, check progress, and report.

Architecture

Mobile API scraper (mobile/scraper.py):

• Hits app.ecourts.gov.in — encrypted mobile API, no CAPTCHA
• Fetches case summary + full history dict inline (always fully enriched)
• Outputs canonical records with phase2_status="enriched"|"no_data", phase1_scraped_at, phase2_scraped_at, source="mobile_api"
• Keeps raw history dict alongside normalised case_summary fields

Web casetype scraper (web/casetype_scraper.py):

• Hits services.ecourts.gov.in — requires CAPTCHA solving
• Phase 1 (submit_case_type) → Phase 2 (viewHistory) inline per CNR
• Outputs same canonical schema, source="web_casetype"

Both write to the same S3 paths — metadata/tar/year=YYYY/state=XX/district=YY/complex=ZZ/metadata.tar. Archive-manager first-writer-wins prevents duplicate CNRs.

State allocation (do not overlap):

Mobile (app.ecourts.gov.in)	Web (services.ecourts.gov.in)
1,2,3,4,5,6,7,8,10,12,14,15,16,17,18,20,21,22,23,26,27,28,30,36,37	9,11,13,19,24,25,29,33,34,35,38

Coverage as of 2026-05-07: 388 complexes done (mobile), 316 done (web, overlapping with mobile). 3,178 complexes remain.

Every Invocation

Step 1: Endpoint Availability + Start/Stop Decisions

# Check both endpoints (10s timeout each)
curl -sk --max-time 10 https://app.ecourts.gov.in/eCourtsAPI/cases/GetStates \
  -o /dev/null -w "mobile_api: HTTP %{http_code} in %{time_total}s\n" 2>&1

curl -sk --max-time 10 https://services.ecourts.gov.in/ecourtindia_v6/ \
  -o /dev/null -w "web_portal: HTTP %{http_code} in %{time_total}s\n" 2>&1

# Scraper process status
tmux has-session -t scraper 2>/dev/null && echo "MOBILE: RUNNING" || echo "MOBILE: DOWN"
tmux has-session -t web-casetype 2>/dev/null && echo "WEB: RUNNING" || echo "WEB: DOWN"

Decision logic — apply after every check:

Mobile API	Web Portal	Action
UP (HTTP 4xx/2xx, <2s)	UP	Run both. Mobile: 2 parallel-complexes. Web: 2 workers.
UP	DOWN (timeout/000)	Stop web-casetype if 100% session init failures for >15 min. Start/keep mobile.
DOWN (timeout)	UP	Stop mobile scraper. Start/keep web-casetype.
DOWN	DOWN	Stop both. Wait. Do not restart loops.

Mobile API UP test: HTTP 405 in <2s = UP (405 is expected — POST endpoint, GET gets 405). HTTP 000 or timeout = DOWN.

Web portal DOWN test: HTTP 000 or time_total > 9s = DOWN.

Stopping a scraper (when its endpoint is down for >15 min):

# Stop mobile
tmux send-keys -t scraper C-c
sleep 2
tmux kill-session -t scraper 2>/dev/null

# Stop web
tmux send-keys -t web-casetype C-c
sleep 2
tmux kill-session -t web-casetype 2>/dev/null

Starting a scraper:

# Start mobile (from project root)
cd ~/judgments/indian-district-court-judgments
tmux new-session -d -s scraper 'mobile/run_scraper.sh'

# Start web (from project root)
cd ~/judgments/indian-district-court-judgments
tmux new-session -d -s web-casetype 'web/run_casetype_scraper.sh'

Log start/stop decisions to ~/.scraper-operator/incidents.log.

Step 2: Log Analysis

Read last 200 lines of each active scraper's log.

Mobile error patterns:

• connection_reset: "RemoteDisconnected", "Connection aborted"
• timeout: "ConnectTimeout", "ReadTimeout"
• auth_failure: "Not in session", "401", "token"
• history_failed: "Failed to get history for case"

Web error patterns:

• session_init_failed: "session init failed, skipping"
• captcha_failure: "captcha failed"
• captcha_rejection: "captcha" in errormsg JSON
• rate_limit: "405", 30s wait messages
• timeout: "ConnectTimeout"

Anomaly thresholds:

• Either scraper: 100% session init failures sustained >15 min → stop it (endpoint down)
• Mobile: history_failed > 20% of cases → API degraded, note in report
• Web: captcha rejection > 30% → CAPTCHA model mismatch, reduce to 1 worker
• Either: zero new cases > 45 min AND endpoint is UP → debug
• Disk free < 5GB → alert immediately

Time context (IST = UTC+5:30):

• 09:00–13:00 weekdays: peak — timeouts/rate-limiting expected, do not trigger debug for these alone
• 20:00–08:00 / weekends: off-peak, best throughput

Step 3: Progress Check

# Mobile: current complex and cases
tail -100 ~/scraper.log | grep -E "complex=|cases_found|Progress|ERROR" | tail -20

# Web: recent finds and progress
tail -100 ~/web_casetype.log | grep -E "found, [0-9]+ saved|DONE —|Progress:" | tail -20

# Cases per hour — web (last 60 min)
awk -v cutoff="$(date -v-60M '+%Y-%m-%d %H:%M' 2>/dev/null || date -d '60 minutes ago' '+%Y-%m-%d %H:%M')" \
  '$0 > cutoff && /saved$/ {match($0, /([0-9]+) saved/, a); sum+=a[1]} END{print sum " web cases/60min"}' \
  ~/web_casetype.log 2>/dev/null

# Data sizes
du -sh ~/judgments/indian-district-court-judgments/mobile/local_mobile_data/ 2>/dev/null
du -sh ~/judgments/indian-district-court-judgments/local_casetype_data/ 2>/dev/null

# Disk free
df -h ~ | tail -1

Step 4: Data Quality Spot Check (every other invocation)

# Web — most recent metadata tar
TARFILE=$(find ~/judgments/indian-district-court-judgments/local_casetype_data -name 'metadata.tar' \
  2>/dev/null | xargs ls -t 2>/dev/null | head -1)
if [ -n "$TARFILE" ]; then
  MEMBER=$(tar -tf "$TARFILE" 2>/dev/null | grep '\.json' | head -1)
  tar -xOf "$TARFILE" "$MEMBER" 2>/dev/null | python3 -c "
import json,sys; d=json.load(sys.stdin); cs=d.get('case_summary',{})
print({'cnr':cs.get('cino'),'source':d.get('source'),
  'phase2_status':d.get('phase2_status'),'phase1_scraped_at':d.get('phase1_scraped_at'),
  'has_case_history':bool(d.get('case_history'))})"
fi

# Mobile — most recent local tar
TARFILE=$(find ~/judgments/indian-district-court-judgments/mobile/local_mobile_data -name 'metadata.tar' \
  2>/dev/null | xargs ls -t 2>/dev/null | head -1)
if [ -n "$TARFILE" ]; then
  MEMBER=$(tar -tf "$TARFILE" 2>/dev/null | grep '\.json' | head -1)
  tar -xOf "$TARFILE" "$MEMBER" 2>/dev/null | python3 -c "
import json,sys; d=json.load(sys.stdin); cs=d.get('case_summary',{})
print({'cnr':cs.get('cino'),'source':d.get('source'),
  'phase2_status':d.get('phase2_status'),'phase1_scraped_at':d.get('phase1_scraped_at'),
  'filing_date':cs.get('filing_date')})"
fi

Both sources must have: phase1_scraped_at, phase2_status in {enriched,no_data,skipped,failed}, source set.

Touch ~/.scraper-operator/last_quality_check after check.

Step 5: State Persistence

python3 << 'EOF'
import json, datetime, pathlib, re

IST = datetime.timezone(datetime.timedelta(hours=5, minutes=30))
op_dir = pathlib.Path.home() / '.scraper-operator'

def running(session): 
    import subprocess
    return subprocess.run(['tmux','has-session','-t',session],
                         capture_output=True).returncode == 0

# Parse web log progress
web_done, web_total, web_cases = 0, 3566, 0
try:
    log = (pathlib.Path.home() / 'web_casetype.log').read_text(errors='ignore')
    prog = re.findall(r'Progress: (\d+)/(\d+)', log)
    if prog: web_done, web_total = int(prog[-1][0]), int(prog[-1][1])
    web_cases = sum(int(m) for m in re.findall(r'(\d+) saved', log[-100000:]))
except: pass

# Parse mobile log progress
mobile_cases = 0
try:
    log = (pathlib.Path.home() / 'scraper.log').read_text(errors='ignore')
    mobile_cases = sum(int(m) for m in re.findall(r'cases_found["\s:]+(\d+)', log[-100000:]))
except: pass

state = {
    'timestamp': datetime.datetime.now(IST).isoformat(),
    'mobile_running': running('scraper'),
    'web_running': running('web-casetype'),
    'web_complexes_done': web_done,
    'web_complexes_total': web_total,
    'web_cases_saved': web_cases,
    'mobile_cases_found': mobile_cases,
    'anomalies_detected': [],
}
(op_dir / 'run_state.json').write_text(json.dumps(state, indent=2))
print('run_state.json updated')
EOF

Debug Mode

Endpoint-specific debugging

Mobile API down:

cd ~/judgments/indian-district-court-judgments/mobile
AWS_PROFILE=dattam-od uv run python -c "
from api_client import MobileAPIClient; c = MobileAPIClient()
c.initialize_session(); print(len(c.get_states()), 'states')" 2>&1

If fails with auth/decrypt error → API changed. If timeout → server down, wait.

Web portal down:

curl -sk --max-time 10 https://services.ecourts.gov.in/ecourtindia_v6/ -o /dev/null \
  -w "HTTP %{http_code} in %{time_total}s\n"

HTTP 000 or timeout → server down, do NOT restart web scraper loops.

CAPTCHA rejection > 30%:

1. ls ~/judgments/indian-district-court-judgments/captcha-failures/ | wc -l
2. Reduce web workers to 1: edit run_casetype_scraper.sh, restart session

Rate limiting (405 surge on web): Reduce --max_workers to 1 in run_casetype_scraper.sh. Commit, restart.

Applying fixes

1. Edit file, commit: git add <files> && git commit -m "operator: <fix>"
2. Restart affected session
3. Append to ~/.scraper-operator/incidents.log

Constraints

• No S3 reads in routine monitoring — local logs and state files only
• Do NOT push code changes to remote
• Do NOT modify S3 data directly
• Do NOT change AWS credentials or profiles
• Do NOT increase concurrency without evidence it's safe
• Stop a scraper only after confirming its endpoint is consistently unreachable (>15 min), not on first timeout
