CHAPROLA — Agent-First Data Platform

The data platform agents can learn in one pass and operate at million-row scale. Chaprola gives AI agents a structured, serverless data store through plain HTTP calls — no drivers, no ORMs, no infrastructure.

An agent defines a schema by sending sample JSON, writes a short program (19 commands total), compiles it to bytecode, and executes it — all through REST endpoints. Proven on 1,050,000 records. 100M instruction budget per execution. O(1) field access via fixed-record memory model. Every registered user gets a @chaprola.org email address.

Scale

Chaprola is not a toy. The VM processes 1,050,000 NYC taxi trip records in under 3 seconds. Each Lambda runs with 10 GB memory — a 44-character record supports ~103 million rows, a 500-character record supports ~9 million rows. The fixed-record memory model delivers constant-time field access regardless of dataset size — no query planning, no indexing overhead. The 19-command language is small by design: small enough for any LLM to learn in one context window, powerful enough to sort, filter, aggregate, and report across millions of rows.

Quick Start

API Base URL: https://api.chaprola.org

1. Register: POST /register with {"username":"my-agent","passcode":"my-secret","never_expires":true} — returns a JWT token
2. Import data: POST /import with JSON array — creates .F (format) and .DA (data) files
3. Compile: POST /compile with Chaprola source code — produces .PR bytecode
4. Run: POST /run — executes the bytecode program
5. Publish: POST /publish — makes the program publicly accessible
6. Report: POST /report — run a published program (no auth required)
7. Send email: POST /email/send — send from your @chaprola.org address

Authentication

Register or login to get a JWT token. Include these headers on authenticated requests:

• X-Username: your-username
• X-Access-Code: your-jwt-token

Tokens last 90 days by default, or set "never_expires": true at registration.

The Language

Chaprola is a fixed-record data processing language with 19 commands: OPEN, CLOSE, GET, PUT, MOVE, ADD, SUB, MPY, DIV, IF, GOTO, FIND, DEFINE, PRINT, SIZE, SORT, COUNT, INDEX, END. Programs compile to bytecode and execute in a VM with constant-time field access.
