Api Proxy

skill-abra5umente-api-proxy-skill · by abra5umente

Routes API requests through the user's residential proxy to bypass cloud IP blocks. TWO use cases - (1) Runtime fallback when direct curl/fetch fails with 403/blocked errors, use fetch.py for quick retry. (2) Template for building new skills that need proxy routing, copy proxy_helper.py into the new skill.

About

API Proxy Skill

Routes requests through residential IP via proxy.address.here.com.

Runtime Fallback (ad-hoc)

When a direct request fails with 403 or IP blocking, retry through the proxy:

# Simple GET
python3 /mnt/skills/user/api-proxy/scripts/fetch.py "https://api.example.com/endpoint"

# POST with body
python3 /mnt/skills/user/api-proxy/scripts/fetch.py "https://api.example.com/endpoint" POST '{"key": "value"}'

Returns JSON response or {"error": "message"} on failure.

Template Mode (building skills)

When creating skills that need proxy routing:

  1. Copy proxy_helper.py into the new skill's scripts/ folder
  2. Import and use:
from proxy_helper import proxy_get, proxy_request

data = proxy_get("https://api.example.com/endpoint")

data = proxy_request(
    url="https://api.example.com/endpoint",
    method="POST",
    headers={"Authorization": "Bearer xyz"},
    body='{"key": "value"}'
)

New domains require user to add them to ALLOWED_DOMAINS env var and restart the container.

Troubleshooting

| Error | Cause | Fix | |-------|-------|-----| | 403 from proxy | Domain not whitelisted | Ask user to whitelist | | 503 from proxy | Rate limited | Retry after delay | | 504 from proxy | Upstream timeout | Increase timeout | | Connection refused | Container/tunnel down | Check status |
