originalpictures-cli: command-line tool for C2PA Content Credentials, AI watermarking and verification

originalpictures-cli installs the originalpictures command: a safe, scriptable command-line interface to the Original Pictures API. Sign files with C2PA Content Credentials, add an invisible watermark and perceptual fingerprints, declare AI generation, verify what a file declares about its origin, and download signed outputs, from a terminal or a CI job.

pipx install originalpictures-cli
export ORIGINALPICTURES_API_URL=https://api.originalpictures.com
originalpictures auth login            # paste the key at the hidden prompt

It delegates every network operation to originalpictures-sdk; it has no raw-route command and no internal-service access.

What it does

• C2PA signing (sign accept): every job writes a C2PA manifest (Content Credentials) following the C2PA Technical Specification 2.4, recording the file's declared origin.
• Invisible watermark and fingerprinting (--watermark, --fingerprint): optional, so a copy whose metadata was stripped can still be matched to your record.
• AI-generation declaration (--ai-generated): the kind of machine-readable marking that EU AI Act Article 50(2) and the California AI Transparency Act (SB 942) describe.
• Verification (verifications create, verifications get): Content Credentials status, certificate chain and your account's records, reported as declared origin with reason codes.
• Uploads and downloads (uploads file, assets download) with streaming, size bounds and SHA-256 integrity checks.
• Jobs (jobs wait): polls with a bounded deadline and clean Ctrl-C cancellation.

Why use it

• No secrets on the command line. Credentials come only from ORIGINALPICTURES_API_KEY, a hidden prompt, or standard input (auth login --token-stdin). The operating-system keyring stores them; the config file holds only non-secret profile settings.
• Scriptable. --json gives deterministic compact JSON on stdout and canonical JSON errors on stderr, with stable exit codes (below).
• No hand-written JSON for signing. sign accept builds the request from flags.
• Safe by default. Bounded timeouts and response sizes, fresh idempotency keys for operations that need them, and request bodies read from bounded files or stdin, never from argv.

Install

pipx install originalpictures-cli

or

uv tool install originalpictures-cli

Requires Python 3.12 or later. The command is originalpictures. (Earlier pre-release builds also installed an op alias; it was removed because op is the 1Password CLI's command.)

Quickstart

1. Create an API key in the console under API keys (keys start with opk_).

2. Point the CLI at the API and store the key:

   originalpictures config set-api-url https://api.originalpictures.com
   originalpictures auth login
   originalpictures auth status
   

   The CLI's built-in default API URL is a local development address, so set the URL once per profile as above, or export ORIGINALPICTURES_API_URL in each shell.

3. Upload, sign and wait:

   originalpictures --json uploads file photo.jpg --media-type image/jpeg > upload.json
   ASSET=$(jq -r .completion.asset_id upload.json)
   
   originalpictures --json sign accept --asset "$ASSET" --no-watermark --no-fingerprint > job.json
   originalpictures --json jobs wait "$(jq -r .job_id job.json)" --poll-timeout 300 > signed.json
   

4. Download the signed file (checked against the published length and SHA-256):

   originalpictures assets download "$(jq -r .result.asset_id signed.json)" photo.signed.jpg
   

Root options (--json, --profile, --api-url, --timeout, --max-response-bytes) must come before the command group, for example originalpictures --json jobs get job_....

Signing flags

sign accept builds the whole request from flags. Every job signs with C2PA; --watermark/--no-watermark and --fingerprint/--no-fingerprint choose what else it adds. Send both every time.

--input FILE (or - for standard input) still supplies a JSON body; a flag and the same field in the body must agree. --strength is an alias of --watermark-strength.

Examples

1. C2PA Content Credentials only

originalpictures sign accept --asset ast_… --no-watermark --no-fingerprint

2. Invisible watermark and fingerprints, then C2PA

originalpictures sign accept --asset ast_… --watermark --fingerprint \
  --watermark-algorithm pixelseal --watermark-strength subtle

originalpictures capabilities show lists the media types, recipes, watermark and fingerprint algorithms your deployment offers.

3. Declare AI generation (sign-only)

originalpictures sign accept --asset ast_… --no-watermark --fingerprint \
  --ai-generated --software-agent "Studio Nova Imagine" --software-agent-version 2.0

--ai-generated with --watermark is refused before any request is sent: "AI-generated mark needs a sign-only call (C2PA claim plan)".

4. Verify a file

originalpictures --json uploads file received.jpg --media-type image/jpeg > upload.json
jq '{object_id: .completion.asset_object_id}' upload.json \
  | originalpictures --json verifications create --input - > verification.json
originalpictures --json verifications get "$(jq -r .verification_id verification.json)"

The result reports what the file declares about its origin and whether your account has a record of it. It is never a judgement about the content itself.

5. CI pipeline (GitHub Actions, GitLab, Jenkins)

# The key comes from the CI secret store as an environment variable, never as an argument.
export ORIGINALPICTURES_API_KEY="$OP_SIGNING_KEY"
export ORIGINALPICTURES_API_URL=https://api.originalpictures.com
for file in build/images/*.png; do
  asset=$(originalpictures --json uploads file "$file" --media-type image/png | jq -r .completion.asset_id)
  originalpictures --json sign accept --asset "$asset" --watermark --fingerprint | jq -r .job_id
done

6. Several accounts with profiles

originalpictures --profile staging config set-api-url https://api.originalpictures.com
originalpictures --profile staging auth login --token-stdin < staging-key.txt
originalpictures --profile staging --json user show
originalpictures config profiles

Configuration

Mutation bodies use --input FILE and explicit operation parameters use --parameters FILE; - reads the JSON object from standard input. Run originalpictures --help for every command group: assets, auth, billing, capabilities, capture, config, governance, history, jobs, keys, shares, sign, uploads, usage, user, verifications, webhooks.

FAQ

Is this C2PA? Yes. Signing writes standard C2PA manifests (Content Credentials) that any C2PA-aware validator, such as c2patool, can read. Original Pictures is listed on the C2PA Conforming Products List as a generator product under the C2PA Conformance Program 0.2 (C2PA Technical Specification 2.4).

Is Original Pictures audited? Original Pictures Technologies, Inc. holds ISO/IEC 27001:2022 certification for its information security management system (GCAI, certificate GCAI-ISMS-PD91) and ISO/IEC 42001:2023 certification for its AI management system (TNV). It has a SOC 2 Type I report from Percilchofe CPA LLC as of 19 October 2026, and runs a GDPR compliance program. The certifications cover management systems, not this package. See Security and compliance.

Does it store my media? Uploaded files are processed on Original Pictures' private servers, encrypted in transit and at rest, in isolated processing. Published outputs are kept for the retention your API key selects (new accounts default to 72 hours). Operator views show metadata only, and emergency access is audited. This is private server processing, not end-to-end encryption.

What formats are supported? Embedded C2PA for JPEG, PNG, WebP, TIFF, AVIF, WAV, MP3, AAC (.m4a) and MP4 (H.264/AAC); sign-only embedding for GIF, JPEG XL, SVG, DNG, HEIC/HEIF, QuickTime, AVI and FLAC; a sidecar .c2pa manifest for PDF, EPUB, DOCX, text, fonts and ML model files. Run originalpictures capabilities show for the live list.

Why was the op command removed? op is the 1Password CLI. Installing a second op would shadow it on your PATH.

How much does it cost? See pricing.

How do I get an API key? Sign in to the console and create one under API keys.
