Ringer API Support

Next-generation Telique API with enhanced capabilities and performance.
    
This development version includes:
- LERG (Local Exchange Routing Guide) data access
- LRN (Location Routing Number) lookups
- Enhanced performance with sub-microsecond response times
- Expanded data coverage and real-time updates

Note: This is a development version. Use the production Telique API for stable deployments.

Proprietary

Telique Dev API

Returns current statistics about the in-memory data store

Checks if the given phone number is in the Do Not Originate (DNO) list.
Returns a boolean indicating whether the number should not be originated.


Phone number to check (10-digit US number)

phone_number

format

Check if a phone number is Do Not Originate

Performs a Local Routing Number (LRN) lookup for the given phone number.
Returns the LRN and optional metadata including SPID, LNP type, and activation timestamp.


Lookup LRN for a phone number (POST method)

Performs a Local Routing Number (LRN) lookup for the given phone number using a simple GET request.
Default response format is plain text "LRN;SPID" format.


Phone number to lookup (10-digit US number without separators)

Response format (default is plain text "LRN;SPID")

Lookup LRN for a phone number (GET method)

Query the LSMS PostgreSQL database to list all Local Routing Numbers (LRNs) associated 
with a given SPID or phone number.


Service Provider ID to filter by (4 characters)

spid

Query the LSMS PostgreSQL database to list all phone numbers associated with a given LRN or SPID.

**Note**: These endpoints query the PostgreSQL database directly and may have higher latency 
than the primary LRN lookup endpoints which use the in-memory data store.


Local Routing Number to filter by (10-digit)

Query the LSMS PostgreSQL database to list all Service Provider IDs (SPIDs) associated 
with a given LRN or phone number.


Basic service health check that always returns healthy if the service is running

Returns the complete OpenAPI 3.0 specification in YAML format

Complete OpenAPI 3.0 specification in YAML format

Execute complex queries using a JSON request body. Supports advanced filtering
and future join operations between tables.


Checks if the service and its dependencies (data store) are ready to handle requests

Returns statistics about the loaded LERG data including table counts and memory usage

Returns metadata for all 27 LERG tables including field information

Returns detailed metadata for a specific LERG table

Name of the LERG table (e.g., lerg_1, lerg_6, lerg_8)

table_name

Returns the schema information for a specific LERG table including column names, types, and nullability

Perform dynamic queries on any LERG table with field selection and filtering.

## URL Format
- `table_name`: The LERG table to query (e.g., lerg_6)
- `fields`: Comma-separated list of fields to return (e.g., npa,nxx,loc_name)
- `query`: Filter conditions as key=value pairs separated by & (e.g., npa=720&nxx=708&block_id=A)

## Examples
- Get NPAs in Denver: `/lerg_6/npa,nxx,loc_name/loc_name=DENVER`
- Get OCNs in Colorado: `/lerg_1/ocn_num,ocn_name/ocn_state=CO`
- Get specific block: `/lerg_6/lata,ocn,switch/npa=864&nxx=763&block_id=A`

## Note
The API will return only the fields specified in the `fields` parameter. 
All filters in the query string will be applied with AND logic.
