TAP Server Prototype

This is a prototype implementation of a TAP (Table Access Protocol) server.

Endpoints

• GET/POST /sync - Synchronous query endpoint
• GET /capabilities - Service capabilities
• GET /tables - Available tables

Example Query

Submit an ADQL query to the /sync endpoint:

curl -X POST https://tap.data.lsdb.io/sync   -d "REQUEST=doQuery"   -d "LANG=ADQL"   -d "QUERY=SELECT TOP 10 ra, dec, mean_mag_g, mean_mag_r, mean_mag_i FROM ztf_dr14 WHERE mean_mag_r < 20"
        

Supported ADQL Features

• SELECT with column list or *
• FROM with table name
• WHERE clause with comparison operators
• CONTAINS with POINT and CIRCLE for cone searches
• TOP/LIMIT clause

Note: This server uses the adql_to_lsdb module to convert ADQL to LSDB operations.
