Configuration Reference

Configuration File Format

Hridaya uses YAML format for configuration. The file must be named config.yaml and placed in the project root directory.

LIMITS Section

Defines rate limiting parameters for Steam API compliance.

Structure

LIMITS:
  REQUESTS: 15
  WINDOW_SECONDS: 60

Parameters

LIMITS.REQUESTS

integer

required

Maximum number of API requests allowed within the time window.Recommended: Start with 15-20 requests per minute. Steam’s actual limits are not publicly documented, so conservative values are safer.Validation: Must be positive integer greater than 0.

LIMITS.WINDOW_SECONDS

integer

required

Duration of the rate limiting window in seconds.Default: 60 seconds (1 minute)Common values:

60 - Per-minute limiting
300 - Per-5-minute limiting
3600 - Per-hour limiting

Validation: Must be positive integer greater than 0.

TRACKING_ITEMS Section

Defines the list of Steam Community Market items to track.

Structure

TRACKING_ITEMS:
  - market_hash_name: "AK-47 | Redline (Field-Tested)"
    appid: 730
    currency: 1
    country: 'US'
    language: 'english'
    polling-interval-in-seconds: 30
    apiid: 'priceoverview'
    item_nameid: 176582392  # Required for some endpoints

Universal Required Parameters

These parameters are required for all tracked items regardless of endpoint:

market_hash_name

string

required

Exact Steam Community Market item name. Must match Steam’s market listing exactly, including special characters and capitalization.Examples:

"AK-47 | Redline (Field-Tested)"
"Revolution Case"
"AWP | Neo-Noir (Factory New)"
"Sticker | Team Liquid | Paris 2023"

Finding the name:

Navigate to the item’s Steam market page
The name appears in the page title and URL (URL-encoded)
Copy exactly as displayed

Wear conditions (Factory New, Minimal Wear, etc.) and StatTrak™ prefixes must be included exactly.

appid

integer

required

Steam Application ID identifying which game/app this item belongs to.Popular App IDs:

App ID	Game/Application
`730`	Counter-Strike 2 (CS2)
`570`	Dota 2
`440`	Team Fortress 2
`252490`	Rust
`753`	Steam (trading cards, backgrounds, emoticons)
`433850`	Blackwake
`578080`	PUBG

Finding App IDs:

Check the item’s market URL: steamcommunity.com/market/listings/{appid}/{item_name}
Visit SteamDB and search for the game

apiid

string

required

Identifies which Steam API endpoint to use for this item.Valid values:

priceoverview - Current prices and 24h volume
itemordershistogram - Full order book (buy/sell orders)
itemordersactivity - Recent trade activity feed
pricehistory - Historical hourly price data

Validation: Must be exactly one of the four values above. See API Endpoints for detailed comparison.

Choose the endpoint based on your use case:

Day trading: itemordersactivity
Price analysis: priceoverview
Market depth: itemordershistogram
Historical trends: pricehistory

polling-interval-in-seconds

integer

required

How frequently to fetch data for this item, in seconds.Minimum recommended: 8 seconds (for high-frequency trading)Common values:

8 - Very high frequency (volatile items)
30 - Medium frequency (active items)
60 - Standard frequency (regular monitoring)
300 - Low frequency (5 minutes)
3600 - Hourly (historical data, pricehistory endpoint)

Validation: Must be positive integer. Lower values consume more rate limit capacity.

Total request load across all items must not exceed your LIMITS.REQUESTS per LIMITS.WINDOW_SECONDS. The system validates this at startup.

Endpoint-Specific Required Parameters

item_nameid

integer

Steam’s internal numeric item identifier.Required for:

itemordershistogram
itemordersactivity

Not required for:

priceoverview
pricehistory

Finding item_nameid:

Open the item’s market page in your browser
Open browser developer tools (F12)
Go to Network tab
Refresh the page
Look for requests to itemordershistogram or similar
The item_nameid parameter appears in the request URL

Example: For “AK-47 | Redline (Field-Tested)”, the item_nameid might be 176582392

The item_nameid is stable for each item - you only need to find it once.

Validation Error Examples

Missing Required Field

TRACKING_ITEMS:
  - market_hash_name: "Revolution Case"
    appid: 730
    # Missing: apiid, polling-interval-in-seconds

Error Output:

❌ CONFIG ERROR: Item 1 missing required field 'apiid'
   Item: {'market_hash_name': 'Revolution Case', 'appid': 730}

Invalid apiid

TRACKING_ITEMS:
  - market_hash_name: "Revolution Case"
    apiid: 'invalid_endpoint'  # Wrong!

Error Output:

❌ CONFIG ERROR: Item 1 has invalid apiid 'invalid_endpoint'
   Valid options: priceoverview, itemordershistogram, itemordersactivity, pricehistory

Missing Endpoint-Specific Field

TRACKING_ITEMS:
  - market_hash_name: "Revolution Case"
    apiid: 'itemordershistogram'
    # Missing: item_nameid (required for this endpoint)

   Item: Revolution Case

Infeasible Rate Limit Configuration

LIMITS:
  REQUESTS: 5  # Too low!
  WINDOW_SECONDS: 60

   Adjust polling intervals or reduce tracked items

Validation Rules Summary

The system validates configurations using these rules (from cerebro.py:validate_required_fields and cerebro.py:validate_config_feasibility):

Required field check: All universal required fields must be present
apiid validation: Must be one of the four valid endpoint identifiers
Endpoint-specific check: item_nameid required for histogram/activity endpoints
Feasibility check: Total request load must not exceed rate limits
Type validation: Fields must have correct types (integers, strings)

The system performs fail-fast validation - it exits immediately on the first error with a descriptive message. Fix errors one at a time and restart.
