Metlife Pets

MetLife Pet Insurance API

You are a helper for interacting with the MetLife Pet Insurance API.

Authentication

Authentication is handled by metlife.sh in the repo root. It supports:

• Programmatic login with username/password (2-step: login + profileDevice, with MFA support)
• MFA handling via email OTP (deliverOtpToDevice + VerifyOtp)
• Automatic token refresh using the refresh token (~15 min access token TTL)
• Token persistence across shell sessions via .metlife-cache/.token
• Proactive refresh before token expiry (120s buffer)

First-time setup / expired session

If ensure_auth returns AUTH_NEEDED, ask the user for their MetLife login credentials:

"I need to log into your MetLife account. What's your email and password for mypets.metlife.com?"

Then call:

source metlife.sh
LOGIN_RESULT=$(metlife_login "user@email.com" "their_password")

If login returns MFA_OTP_SENT (exit code 2): MetLife requires email verification. Ask the user to check their email for a verification code, then call:

source metlife.sh
metlife_verify_otp "123456"

If login completes without MFA: Tokens are saved automatically.

Important (zsh compatibility): Always run metlife.sh with bash or ensure the calling shell is bash. The script uses bash-specific features and avoids zsh reserved variable names.

Every Bash call

Always source metlife.sh and call ensure_auth at the top of every Bash tool invocation:

cd /path/to/claude-metlife
source metlife.sh
AUTH_RESULT=$(ensure_auth)
if [ "$AUTH_RESULT" = "AUTH_NEEDED" ]; then
  echo "AUTH_NEEDED"
  exit 0
fi

If AUTH_NEEDED is returned, stop and ask the user for credentials. Do not proceed with API calls.

Two API Gateways

MetLife uses two separate API gateways. The helper script handles headers for each automatically.

Azure APIM (apis.metlife.com) — pets, policies, rewards

Use metlife_apim for these endpoints:

IBM API Connect (api.metlife.com) — claims, customer, payments

Use metlife_ibm for these endpoints:

You can also use metlife_api which auto-routes to the correct gateway based on the URL.

Document Downloads

Submitted documents (invoices, SOAP notes)

The filePath comes from the docDetails array in the document list response. Use claimDocumentType=1 (not 2). The response may return the document in either docDetails[].document or eobDetails[].eobDocument -- check both fields.

If a download returns null, try the other claimDocumentType and try both petIds on the policy. The API is inconsistent -- some documents only download with a specific petId even if tagged for multiple pets. URL-encode filePaths with spaces.

RESPONSE=$(metlife_ibm "$IBM_BASE/cl/v1/document-details?policyId=$POLICY&claimId=$CLAIM&petId=$PET&isBlobRequest=true&filePath=$FILE_PATH&claimDocumentType=1")
echo "$RESPONSE" | python3 -c "
import sys,json,base64
d=json.load(sys.stdin)
m=d.get('model',{})
for e in (m.get('eobDetails') or []):
    if e.get('eobDocument'):
        open('output.pdf','wb').write(base64.b64decode(e['eobDocument'])); break
else:
    for doc in (m.get('docDetails') or []):
        if doc.get('document'):
            open('output.pdf','wb').write(base64.b64decode(doc['document'])); break
"

EOBs (Explanation of Benefits)

The filePath comes from the eobDetails array (eobFilePath field). Use claimDocumentType=1:

RESPONSE=$(metlife_ibm "$IBM_BASE/cl/v1/document-details?policyId=$POLICY&claimId=$CLAIM&petId=$PET&isBlobRequest=true&filePath=$EOB_PATH&claimDocumentType=1")
echo "$RESPONSE" | python3 -c "import sys,json,base64; data=json.load(sys.stdin); eob=data.get('model',{}).get('eobDetails',None); [open('eob.pdf','wb').write(base64.b64decode(e['eobDocument'])) for e in (eob or []) if e.get('eobDocument')]"

Local Cache

All API responses and downloaded documents are cached in .metlife-cache/.

Cache structure

.metlife-cache/
├── .token                                  # Auth tokens (4 lines: bearer, refresh, expiry, session_id)
├── claims/
│   ├── {policyId}_{petId}_all.json         # All claims list
│   └── {claimSourceId}_{claimId}.json      # Individual claim details
├── documents/
│   ├── {policyId}_{claimId}_{petId}_list.json  # Document list
│   └── {policyId}_{claimId}_{petId}/           # Downloaded files
│       └── {filename}.pdf
└── policies/
    └── {policyId}_packet.pdf               # Policy packet

Cache rules

1. Before any API call, check if the cached file exists. If it does, read from cache.
2. After any successful API call, validate the response with is_cacheable before writing to cache. Never cache error responses.
3. For JSON responses, save the raw JSON. For PDFs, save the decoded file.
4. To force a refresh, the user says "refresh" or "re-fetch" — bypass cache and overwrite.
5. Create directories as needed with mkdir -p.

Caching pattern:

CACHE_FILE=".metlife-cache/claims/${POLICY}_${PET}_all.json"
if [ -f "$CACHE_FILE" ]; then
  RESPONSE=$(cat "$CACHE_FILE")
else
  RESPONSE=$(metlife_ibm "$IBM_BASE/cl/v1/claim/all?petId=$PET&policyId=$POLICY")
  if is_cacheable "$RESPONSE"; then
    mkdir -p "$(dirname "$CACHE_FILE")"
    echo "$RESPONSE" > "$CACHE_FILE"
  else
    echo "ERROR: API call failed. Response: $RESPONSE" >&2
  fi
fi

Instructions

1. Source metlife.sh and call ensure_auth at the top of every Bash tool call. If AUTH_NEEDED, ask for credentials and call metlife_login.
2. Proactively call ensure_auth before multi-step operations to avoid mid-operation failures.
3. Check cache first before making any API call.
4. Validate before caching — use is_cacheable to avoid writing error responses to cache.
5. Use metlife_ibm for claims/documents/policy endpoints, metlife_apim for pets/policies list/rewards, or just metlife_api (auto-routes).
6. Parse JSON responses and present data in readable format (tables, summaries).
7. For document/PDF downloads, save to the cache directory and tell the user the path.
8. If login fails, it may be due to ThreatMetrix device profiling. Tell the user: "Automated login didn't work — MetLife's fraud detection may have blocked it. You can try again, or paste a Bearer token from DevTools as a fallback." To set a manual token: write the bearer token as line 1 and refresh token as line 2 to .metlife-cache/.token.

First-Run Sync

When the user first provides their credentials (or says "sync" or "fetch everything"):

1. Log in if not already authenticated.
2. Fetch all pets via metlife_apim "$APIM_BASE/pets" — get pet IDs and names.
3. Fetch all policies via metlife_apim "$APIM_BASE/policies" — get policy IDs.
4. Fetch all claims for each pet/policy combo. Cache the response.
5. For each claim, fetch claim details and document list. Cache each one.
6. Download every document (EOBs, invoices, SOAP notes) from every claim. Cache them.
7. Download the policy packet. Cache it.
8. Run independent fetches in parallel where possible.
9. Tell the user what was fetched and cached when done.

After sync, all reads come from cache unless the user asks to refresh.
