What it does when it runs
Understand what Cargo is costing — remaining credits, usage broken down by workflow, connector, or agent, subscription state, and invoice history. Triggers: \"how many credits do I have left\", \"what did that cost\", \"why is my bill so high\", \"am I about to run out\", \"will this fit in our budget\", \"show me my invoices\", \"how much have I spent this month\", \"what plan am I on\", \"what do I get for free\", \"how many free credits\", \"can I afford this run\", \"add a card\", \"update my payment method\", \"why was my card declined\". Needs a token with admin access. Skip when: attributing spend to specific nodes or cutting a play cost — use cargo-diagnostics.

This repo ships a .claude-plugin manifest, so Claude Code can install all 20 skills at once. Plugin skills are invoked as /<plugin>:<skill>, so they never collide with your own.
/plugin marketplace add getcargohq/cargo-skills /plugin
The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.
Before you install: this skill will not complete its job on a bare agent. It needs STRIPE_PUBLIC_KEY, which you have to obtain separately.

Cargo CLI — Billing
Billing and credit management: pulling usage metrics, checking subscription status, viewing invoices, and managing credits.

Every command prints JSON to stdout; failures exit non-zero with {"errorMessage": "..."}. Anything that creates a run or a batch is async — pass --wait-until-finished or poll the matching get. Admin-only: every command in this skill requires a token with admin access on the workspace. Non-admin tokens return {"errorMessage":"forbidden"}. When the full skill bundle is installed, ../cargo/references/prerequisites.md adds the CLI version pin, token scopes, and the admin-only surface.

Estimating cost before running a batch
Before triggering a large batch, estimate credit consumption to avoid unexpected charges.
Step 1 — Check current credit balance:
cargo-ai billing subscription get
# → subscriptionAvailableCreditsCount - subscriptionCreditsUsedCount = remaining credits
Step 2 — Estimate cost from a sample run:
Run the workflow on a single record first and measure credits consumed:
# Run on one record
cargo-ai orchestration run create --workflow-uuid <uuid> --data '{...}'
# → poll to completion
# Check credits used for that run
cargo-ai billing usage get-metrics \
--from <today> --to <today> \
--workflow-uuid <uuid>
# → metrics[].items[] for that workflow (the response has one key, `metrics` — there is no `totalUsage`)
Step 3 — Project batch cost:
estimated_cost = (credits_per_record × number_of_records) # provider actions
+ (nodes_per_record × number_of_records / 100) # execution charge
The second term is the 0.01-credit-per-execution platform charge ("The execution charge" below). A sample run measures it for free — the record's execution count is length(run.executions), or one row of --unit orchestration.executions for the sample window. Leave it out and every step-heavy graph is under-quoted.
Compare against subscriptionAvailableCreditsCount - subscriptionCreditsUsedCount before proceeding.
Step 4 — Monitor during the batch:
# Check running costs mid-batch
cargo-ai billing usage get-metrics \
--from <start-date> --to <today> \
--workflow-uuid <uuid>
Cost levers:
| Action | Effect |
|---|---|
Use a cheaper model (e.g. gpt-4o-mini vs gpt-4o) | Significant reduction for AI nodes |
Add filter nodes early in the graph | Skip ineligible records before expensive connector calls |
Set fallbackOnFailure: false | Stop the run early on failures instead of continuing to downstream nodes |
Reduce maxSteps on agent nodes | Limit how many tool calls an agent can make per record |
Cut node count — collapse chained variables, fold branch pairs into one switch | 0.01/execution × records; the only lever for a graph whose spend is steps, not providers |
To find out which node or provider dominates a play's spend before picking a lever, follow the attribution runbook in
../cargo-diagnostics/references/play-optimize-credits.md.
Usage metrics
Pull credit and usage data for any time range, optionally filtered and grouped.
# Basic usage for a period
cargo-ai billing usage get-metrics --from <start-date> --to <end-date>
# Group by dimension
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --group-by workflow_uuid
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --group-by connector_uuid
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --group-by integration_slug
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --group-by model_uuid
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --group-by agent_uuid
# Filter by specific resource
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --workflow-uuid <uuid>
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --agent-uuid <uuid>
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --connector-uuid <uuid>
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --integration-slug <slug>
# One unit at a time — the three below are the only accepted values
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --unit billing.credits
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --unit orchestration.executions
cargo-ai billing usage get-metrics --from <start-date> --to <end-date> --unit storage.records
--group-by values: workflow_uuid, connector_uuid, model_uuid, integration_slug, agent_uuid.
Available filters: --workflow-uuid, --model-uuid, --connector-uuid, --integration-slug, --slug, --agent-uuid. Combine with --group-by and --unit.
The three usage units
--unit takes exactly billing.credits, orchestration.executions, or storage.records — anything else is a 400 that lists them. With no --unit, all three come back interleaved in the same items[] array, and their count fields are not the same quantity. Read the unit off the slug:
| Unit | Slugs in items[] | What count is |
|---|---|---|
billing.credits | integration.<slug>.action.<action>, native.<action>, integration.<slug>.chat, integration.<slug>.extractor.<name> | Credits (fractional) |
orchestration.executions | success, error | Node executions, counted one-for-one — not credits |
storage.records | insert | Records written |
An unqualified call that shows {"slug":"success","count":1043} next to {"slug":"integration.peopleDataLabs.action.queryPeople","count":174} is reporting 1,043 executions beside 174 credits. Pass --unit whenever the number is going into an estimate.
The execution charge
Every node execution bills 0.01 credits — 1 credit per 100 executions. It applies to every node kind and every node, including the structural natives that carry no provider price: branch, filter, switch, split, group, variables, start, end. There is no free step in a workflow.
This charge is not attributed per node. run get → executions[].creditsUsedCount and the spans.execution_credits_used_count column both carry the provider cost alone, and read 0 on a native node that nonetheless billed. Node-by-node attribution therefore under-counts every graph, and the shortfall grows with step count, not with spend.
The only surface that shows it:
cargo-ai billing usage get-metrics --from <YYYY-MM-DD> --to <YYYY-MM-DD> --unit orchestration.executions
# → items[] = [{"slug":"success","count":<executions>}, {"slug":"error","count":<executions>}]
# credits = (success + error) / 100
Cross-check against the runtime tables, which agree row-for-row:
cargo-ai orchestration query execute \
"SELECT execution_status, count() AS executions, count() / 100 AS credits
FROM spans WHERE execution_started_at >= '<YYYY-MM-DD>' GROUP BY execution_status"
Why it matters for estimates. A graph's cost has two terms:
credits = (provider cost per record × records) + (nodes per record × records ÷ 100)
The second term is invisible in the credits cost table, which prices actions, not steps. It is small next to an action-heavy play (a LinkedIn enrich on every record dwarfs its 8 steps) and dominant on step-heavy, action-light ones — a 12-node routing sweep over 20,000 records is 2,400 credits with no provider call at all. Errored executions bill too, so a graph that fails late bills its whole prefix.
Tools fan out. A tool node is one execution plus every node inside the tool's own graph, each billed separately. Extracting a subgraph into a tool is a debuggability win, not a cost saving — it adds one execution per record on top of what the internals already cost. When a graph's execution count exceeds its visible node count, tool nodes are the first place to look: group by node_slug in spans to find them.
Subscription and credits
cargo-ai billing subscription get # current plan, credits used/available, period dates
cargo-ai billing subscription get-invoices # invoice history (amounts in cents)
cargo-ai billing subscription get-credit-card # card on file
cargo-ai billing subscription update-payment-method # add or replace the card (see below)
cargo-ai billing subscription create-portal-session # Stripe portal URL for self-service billing
Remaining credits = subscriptionAvailableCreditsCount - subscriptionCreditsUsedCount from subscription get.
Note: Invoice amounts are returned in cents. Divide by 100 for the dollar value.
The free tier
A new account starts with 100 free credits and no card on file. When subscription get shows a fresh or near-fresh balance, answer cost questions against that budget rather than as an abstract number — "you've used 12 of your 100 free credits" is the useful answer to "how am I doing?", and it is also the honest one when the user is deciding whether to keep going.
What 100 credits buys, as ballpark anchors (per-action costs in ../cargo-gtm/references/credits-cost-table.md):
| Work | Cost | 100 credits ≈ |
|---|---|---|
Source leads — salesNavigator.searchLeads | 0.02/record | ~5,000 leads |
Enrich from a LinkedIn URL + verified email — aiArk.enrichPerson | 0.1 | ~1,000 people |
Verify an email — waterfall.verifyEmail | 0.1 | ~1,000 checks |
Full contact enrichment — waterfall.enrichContact | 2 | ~50 contacts |
Find a phone — FullEnrich.findPhone | 6 | ~16 numbers |
The quickstart demo spends about 0.5. Phone lookups are the fastest way to burn a free tier, so phone is the guarded lever: the escalation tier runs 3–7 credits/record, ~10× email, and never belongs in a default chain — it enters a plan only on explicit user request, on qualified leads only. Full spend rules in ../cargo-gtm/references/cost-discipline.md.
Adding a card
A workspace holds exactly one card. update-payment-method sets it, whether or not one is already on file, and takes the details three ways.
# Card details — no browser, nothing to hand off
cargo-ai billing subscription update-payment-method \
--card-number 4242424242424242 --card-exp 12/2030 --card-cvc 123
# Same, but keeps the number out of shell history and the process list
echo '{"number":"4242424242424242","expMonth":12,"expYear":2030,"cvc":"123"}' \
| cargo-ai billing subscription update-payment-method --card-stdin
# No card details — prints a Stripe-hosted form URL and waits for the card to land
cargo-ai billing subscription update-payment-method
Prefer --card-stdin. Anything passed as a flag is visible in shell history and to any process that can read the process list. Card details go from your machine straight to Stripe in exchange for a token; they never reach the Cargo API, and no output prints them.
Never invent card details, and never reuse a number from elsewhere in the conversation. Ask the user for them, or use the no-argument form and hand them the URL.
The no-argument form is the fallback when you have no details to submit: it prints a URL that opens directly on the card form, then polls until the card changes (--timeout, --poll-interval, --no-open). Relay that URL to the user — it works over SSH and in sandboxes.
Either way the card is verified against the issuer before it becomes the default, so a card that cannot be charged fails here rather than silently at the next renewal.
| Failure | What it means | What to do |
|---|---|---|
cardDeclined + declineCode | The issuer refused the verification | Read declineCode. On a spend-limited virtual card, insufficient_funds or a limit code means the budget or merchant restrictions rule us out — ask the cardholder to raise it |
authenticationRequired | The card wants 3-D Secure, which needs the cardholder present | Re-run with no arguments and hand the user the hosted-form URL |
paymentMethodNotFound | The details did not resolve to a usable card | Re-check the number and expiry with the user |
Card updates are rate-limited to 10 per hour per workspace (shared with setup intents). Retrying a declined card burns that budget — fix the cause rather than looping.
