Health check — verify the Chaprola API is running

Register a new Chaprola account. Returns an API key — save it immediately

Login and get a new API key. WARNING: invalidates the previous API key

Check if a username is available before registering

Delete an account and all associated data. Requires passcode confirmation

Get the current Business Associate Agreement text and version. Present to human for review before signing

Run a published program and return output. No auth required — program must be published first via /publish

Sign the BAA. STOP: You MUST call chaprola_baa_text first, show the FULL text to the human, and get their EXPLICIT typed approval before calling this. Never sign automatically. Only needed for PHI — non-PHI data works without a BAA.

Check whether the authenticated user has signed the BAA

Import JSON data into Chaprola format files (.F + .DA). Sign BAA first if handling PHI

Get a presigned S3 upload URL for large files (bypasses 6MB API Gateway limit)

Process a file previously uploaded to S3 via presigned URL. Generates .F + .DA files

Import data directly from a public URL (CSV, TSV, JSON, NDJSON, Parquet, Excel). Optional AI-powered schema inference

Export Chaprola .DA + .F files back to JSON

List files in a project with optional wildcard pattern

Compile Chaprola source (.CS) to bytecode (.PR). READ chaprola://cookbook BEFORE writing source. Key syntax: no PROGRAM keyword (start with commands), no commas, MOVE+PRINT 0 buffer model (not PRINT field), SEEK for primary records, OPEN/READ/WRITE/CLOSE for secondary files, LET supports one operation (no parentheses), field addressing via P.field/S.field requires primary_format/secondary_format params.

Execute a compiled .PR program. Use async:true for large datasets (>100K records)

Check status of an async job. Returns full output when done

Run a compiled .PR program against every record in a data file. Like CHAPRPG from the original SCIOS. Use this for scoring, bulk updates, conditional logic across records.

Publish a compiled program for public access via /report

Remove public access from a published program

Run a .PR program and save output as a persistent .R file in S3

Get a presigned S3 URL to download any file you own (1-hour expiry)

SQL-free data query with WHERE, SELECT, aggregation, ORDER BY, JOIN, pivot, and Mercury scoring

Sort a data file by one or more fields. Modifies the file in place

Build an index file (.IDX) for fast lookups on a field

Merge two sorted data files into one. Both must share the same format (.F)

Inspect a data file's schema — returns field names, positions, lengths, types, and PHI flags

Modify a data file's schema: widen/narrow/rename fields, add new fields, drop fields. Transforms existing data to match the new schema.

Run HULDRA nonlinear optimization using a compiled .PR as the objective evaluator

Check status of an async optimization job

List emails in the authenticated user's mailbox

Read a specific email by message_id

Send an email from your @chaprola.org address. Subject to content moderation

Delete a specific email from your mailbox

Search the web via Brave Search API. Returns titles, URLs, and snippets. Optional AI-grounded summary. Rate limit: 10/day per user

Fetch any URL and return clean content. HTML pages converted to markdown. SSRF-protected. Rate limit: 20/day per user

Create a scheduled job that runs a Chaprola endpoint on a recurring cron. Max 10 schedules/user, 15-min minimum interval

List all scheduled jobs for the authenticated user with run history and next execution time

Delete a scheduled job by name

Insert a new record into a data file's merge file (.MRG). The record appears at the end of the file until consolidation.

Update fields in a single record matched by a where clause. If no sort-key changes, updates in place; otherwise marks old record ignored and appends to merge file.

Delete a single record matched by a where clause. Marks the record as ignored (.IGN). Physically removed on consolidation.

Merge a .MRG file into its parent .DA, producing a clean sorted data file. Deletes .MRG and .IGN after success. Aborts if .MRG was modified during the operation.
