Tokens

Drive In Perpetuity from your own code

Both metered lanes are available over HTTP: the term review (a brand's offer read clause by clause, with a sign / counter / walk-away verdict and what to ask for) and the counter email (the reply a creator sends back: accept, counter or decline, with line items and a total ask). A natural use is a creator's inbox helper or a talent-manager tool: your code sends the offer, the term sheet and the page's quote, and gets back a structured review or a ready-to-paste email.

The division of labour first: the page reads and prices; the model judges and writes; the page re-checks every quote and figure the model gives. Reading the offer into terms, the rule-of-thumb add-ons on the creator's base rate (all estimates, not market data), the flags and the page's verdict come from dealkit.js, which runs in node as well as in the browser. Its check function holds each reply to the offer: a clause quote must be the offer's own words, a deal-breaker the page flagged must be answered, line items must add up to the total, and the total must be at or above the brand's offer and the creator's minimum. Not legal advice.

Get a token on the token page (step 2 below also shows how to mint a guest token in code).

Base URL and the envelope

Every endpoint lives under https://api.skillsafe.ai/v1/app-api, and every response uses one envelope:

{ "ok": true,  "data":  { ... } }
{ "ok": false, "error": { "code": "...", "message": "...", "status": 402, "details": { ... } } }

The token is minted for this app (the guest call takes {"slug":"in-perpetuity"}), so no slug header is needed afterwards. Send it as Authorization: Bearer …. The run body is the input object, sent bare: never wrap it as {"input": {…}}.

StatusCodeMeaning
400validation_errorThe body is not a JSON object, or task / offer is missing.
401unauthorizedNo token, or a stale one. Mint a guest token or sign in again.
402insufficient_creditsThe balance is under min_credits. Price with /estimate first.
403forbiddenA guest token tried to run: both lanes are metered and need a personal token.
404not_foundUnknown job id.
429rate_limitedBack off and retry.
5xxserver_errorTransient. Retry with the same Idempotency-Key so a retry never double-bills.

The task field comes first

Every run sends task: review or counter. Both share the offer fields; the counter lane adds its own. The model follows only the named task's contract.

TaskVerdictsReply fields
reviewsign (fair as written), counter (workable once the asks are met), walk (a deal-breaker, or pay so far under the estimate that a counter would have to more than double it)title, verdict, summary, clauses [{quote, topic, level: ok|negotiate|walk, note, ask}], missing [{term, why}], asks [{ask, priority: must|nice}], numbers (strings)
counteraccept (yes, with the terms restated in writing), counter (changed terms and a price), decline (a polite no naming what would change it)title, verdict, summary, subject, email (plain text), line_items [{item, offered, asking, why}], total_ask (number or null), walk_away, trades (strings), followup

Clause topics: deliverables, fee, usage, paid_ads, whitelisting, exclusivity, revisions, payment, raw_footage, hooks, timeline, rights, ai_likeness, disclosure, kill_fee, other. The declared input schema carries scalars only, so object-valued fields travel JSON-encoded as strings (DealKit.toWire does this). The schema requires task and offer.

The reply

The job's output.output is a string holding one JSON object. Parse it with DealKit.parseReply, then normalize(reply, task), then check(reply, state, task), which returns {notes, marks}: the page's notes (info, warn) shown under "Checked by the page", and for a review, each clause's span in the offer (null when its quote is not the offer's own words).

Worked examples

Replies produced against the app's prompt for the sample offers (made up; lists shortened, emails folded; the full replies ship in example-result.js). Together they cover every verdict. The page replays each of them free from its sample buttons.

 "summary": "This offer pays nothing in cash for four videos plus a never-ending paid-ad and AI-generated-likeness licence, twelve months of exclusivity, and unlimited revisions - the page's estimate puts the fair value of what's being asked at about $4,280 against $0 offered. That gap, combined with deal-breakers that need rewriting rather than just a bigger check, makes a straight counter unrealistic, so declining while naming exactly what would change the answer is the better move. If the brand comes back with a cash fee, a defined usage window, no AI use of likeness, capped revisions, and a short, paid, narrowly defined exclusivity, this could work.",

 "email": "Hi Fizzlorn team,\n\nThank you for thinking of me for the creator family!\n\nHaving looked at the details, I don't think I can say yes to this version of the offer. As written, it's product only - no cash fee - in exchange for four videos plus the right to run my face and voice in paid ads with no end date, make AI-generated versions of me, twelve months of exclusivity in the beverage category, and unlimited revisions. By my own estimate, pricing out everything this offer is asking for comes to roughly $4,280, so a product package worth $180 doesn't come close.\n\nHere's what would change my answer: a cash fee in that range, a set usage window (3-12 months) with a renewal fee instead of forever, no AI-generated use of my likeness or voice, one or two revision rounds with a fee for extra ones, and a shorter, narrowly defined, paid exclusivity period.\n\n[... 4 more lines]",

Build the input yourself

Load the script in node (global.window = {}; require("./dealkit.js")), then:

const K = DealKit;
const offer = "Hi! We'd love 2 UGC videos. $600 total, 3 months of paid usage on Meta, one round of revisions, net 30.";
const terms = K.readTerms(offer).terms;          // the term sheet as the page reads it - correct any field
const st = K.state(Object.assign({ offer, base: "300", currency: "USD", creator: "", brand: "" }, terms));
console.log(st.quote.fair, st.quote.ratio, st.flags, st.verdict);   // estimate, share of it offered, flags, sign|counter|walk
const wire = K.toWire(K.buildInput(st, "review", { today: "2026-10-20" }).input);  // POST this to /estimate and /run
// counter lane: set st.form.asks (or the "asks" form field) to K.asksToText(reviewReply), then buildInput(st, "counter")
// later: const reply = K.normalize(K.parseReply(job.output.output), "review");
// const { notes, marks } = K.check(reply, st, "review");

Step 1 — a tiny client helper

One function that sends JSON and unwraps the envelope. Paste a personal token from /tokens.html, or leave it empty and mint a guest token in step 2.

BASE="https://api.skillsafe.ai/v1/app-api"
TOKEN="paste-your-token-here"   # from https://in-perpetuity.skillsafe.ai/tokens.html
api() { # api METHOD PATH [JSON-BODY]
  curl -s -X "$1" "$BASE$2" -H "Content-Type: application/json" \
    ${TOKEN:+-H "Authorization: Bearer $TOKEN"} ${3:+--data "$3"}
}

Step 2 — a token

A guest token is enough for /me and /estimate. A run is metered, so it needs a personal token: sign in on /tokens.html and copy it from there.

# a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
TOKEN=$(curl -s -X POST "$BASE/guest" -H "Content-Type: application/json" -d '{"slug":"in-perpetuity"}' | jq -r '.data.token')

Step 3 — GET /me

Who the token is (subject_type: user or guest) and the credit balance.

api GET /me | jq '.data | {subject_type, credits}'

Step 4 — POST /estimate

Free. The body is the run input itself, the bare object (never wrapped in {"input": ...}). hold_credits is a reservation, not the price; min_credits is what the balance must cover; model_alias reads gpt-terra.

# input.json: the run input object - {"task": "review", "today": "2026-10-20", "creator": "Dev P.", "brand": "Panwhistle", "currency": "USD", "base_rate": "250", "offer": "Hey Dev, Panwhistle here! ...", "terms": "{...}", "quote": "{...}", "page_flags": "[...]", "page_verdict": "counter"}
api POST /estimate "$(cat input.json)" | jq '.data | {hold_credits, min_credits, model, model_alias, markup_bps, warnings}'

Step 5 — POST /run, then poll the job

Send an Idempotency-Key built from the lane and the input: a retry with the same key never bills twice. The page uses in-perpetuity:<task>:<inputHash>:a<attempt> (the examples below use the review lane), and its one reformat retry (with retry_note added) is attempt 2, a new key and a second run. The job's output.output is the reply text; truncated: true means the balance cut it short.

KEY="in-perpetuity:review:$(shasum -a 256 input.json | cut -c1-16):a1"
JOB=$(curl -s -X POST "$BASE/run" -H "Content-Type: application/json" -H "Authorization: Bearer $TOKEN" \
  -H "Idempotency-Key: $KEY" --data @input.json | jq -r '.data.job_id')
while :; do
  J=$(api GET "/jobs/$JOB"); S=$(echo "$J" | jq -r '.data.status')
  case "$S" in succeeded|failed|cancelled) break;; esac; sleep 2
done
echo "$J" | jq -r '.data.output.output' > reply.json   # one JSON object, the reply contract
echo "$J" | jq '.data | {charged_credits, truncated}'

Step 6 — POST /run-stream

The same run as Server-Sent Events, with the same input.json. Browsers receive progress ticks rather than text deltas; the final done event carries the reply.

# Server-Sent Events: tick/delta events while the job runs, then a final event with the job
curl -N -s -X POST "$BASE/run-stream" -H "Content-Type: application/json" -H "Authorization: Bearer $TOKEN" \
  -H "Idempotency-Key: in-perpetuity:review:$(shasum -a 256 input.json | cut -c1-16):a1" --data @input.json
