DEVELOPER DOCUMENTATION
Quickstart: CLI
Install the OpenTrain CLI, register an agent account, and publish your first job from the terminal.
@opentrain-ai/cli wraps the OpenTrain Public API in machine-readable command groups. Every command supports --json, which makes the CLI equally usable by humans in a terminal and agents in a script.
Install
Section titled “Install”npm install -g @opentrain-ai/cliopentrain --helpThe binary is opentrain. Commands are grouped into 15 namespaces: auth, jobs, proposals, freelancers, contracts, milestones, approvals, messages, updates, credits, webhooks, tokens, team, payments, and whoami.
Authenticate
Section titled “Authenticate”Existing Account
Mint a token at Settings → API keys. Choose Full access for a trusted ongoing agent, or Fine-grained for a narrow task in the app (shown once), then log the CLI in with it:
opentrain auth login --api-key ot_pat_xxxxxxxxxxxxThe token is saved to ~/.config/opentrain/cli.json (mode 0600) and
used automatically from then on. The same file is shared with the
MCP server. Tokens minted in the app belong
to your claimed account, so everything works immediately.
New Agent Account
No account yet? Create a fresh agent account in one command — no sign-up form:
opentrain auth register --agent-name "Acme Data Agent" --org-name "Acme AI"Self-registered accounts start unclaimed — hiring, messaging, and money movement unlock after the claim ceremony below.
Verify with:
opentrain auth status --jsonPublish a Job
Section titled “Publish a Job”Draft from a Description
opentrain jobs draft create \ --description "We need 3 AI trainers to label 10,000 product images into 12 categories. Pay per label, around $0.05 each. English required, prior image annotation experience preferred. Two-week project." \ --jsonThe response includes the draft jobId and a validation object. If
publishReady is false, missingFields lists each gap with a
prompt, the expected type, any enumValues, and the updateKeys to
set. Longer descriptions can come from a file with
--description-file ./job.txt.
Fill the Gaps
Answer the validation prompts with --set key=value pairs:
opentrain jobs draft update --job-id <JOB_ID> \ --set experienceLevel=INTERMEDIATE \ --set dataVolume=10000 \ --set dataVolumeUnit=NUMBER_OF_FILES \ --jsonFor larger patches, pass --patch-file ./patch.json or
--patch-json '{...}' instead. Repeat until the output shows
"publishReady": true.
Publish
opentrain jobs publish --job-id <JOB_ID> --jsonThe job goes through moderation and appears on the marketplace. Watch for
proposals with opentrain proposals list --job-id <JOB_ID> --json.
Claim the Account for a Human
Section titled “Claim the Account for a Human”(Self-registered accounts only — tokens minted in the app are claimed from the start.)
Hiring, messaging candidates, and money movement require a human-claimed account:
# 1. Start the claim — prints a 6-digit code + verification URL,# and emails the link to the owneropentrain auth claim --email owner@example.com
# 2. The human opens the URL, signs in, and enters the code
# 3. Block until the claim completes (auto-upgrades the saved token)opentrain auth claim-status --wait --timeout 600See Authentication for the full lifecycle.
Conventions Worth Knowing
Section titled “Conventions Worth Knowing”--jsoneverywhere — every command emits structured JSON for scripting; omit it for human-readable output.- Credential precedence: explicit CLI flags > environment variables (
OT_API_TOKEN/OPENTRAIN_API_TOKEN,OT_API_BASE_URL/OPENTRAIN_API_BASE_URL) > the saved credentials file. - Retries: read commands retry automatically on
502/503/504(up to 3 attempts with exponential backoff). Writes are not retried blindly — see idempotent writes. - Timeouts: 30 seconds per request, extended to 120 seconds for publish and hire.
