Drive Fold and Look from your own code
The one metered task, read-blots, is available over HTTP. It takes your answers to a set of 5 inkblots - what you saw in each and whether the answer uses the whole blot or a part, with skipped blots allowed - plus the page's own tally (usual or your own, word count, the second-look angle per blot), and returns a verdict, a playful reading and a second-look question for every answered blot, the thread your answers share, a headline and a closing line. It is a game, not a psychological test.
The division of labour first: the page tallies the answers and a fixed rule decides the verdict; the model reads them. After a run the page checks that the verdict follows the rule, that every answered blot is read in order with the page's usual-or-own mark, that each second look is a question, and that no ids or test words leak into the prose.
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": "..." } }
The token is minted for this app (the guest call takes {"slug":"fold-and-look"}), so no slug header is needed afterwards. Send it as Authorization: Bearer …. The run body is the input object, sent bare.
| Status | Code | Meaning |
|---|---|---|
| 400 | validation_error | The body is not a JSON object, or a required field (task, answers, tally) is missing. |
| 401 | unauthorized | No token, or a stale one. Mint a guest token or sign in again. |
| 402 | insufficient_credits | The balance is under min_credits. Price with /estimate first. |
| 403 | forbidden | A guest token tried to run: a reading is metered and needs a personal sign-in. |
| 404 | not_found | Unknown job id. |
| 429 | rate_limited | Back off and retry. |
| 5xx | server_error | Transient. Retry with the same Idempotency-Key so a retry never double-bills. |
The task field, the input and the verdicts
Every run sends task: read-blots (the one task is read-blots); a missing or different one is still answered as read-blots. The verdict rule, checked in order: if usual answers are at least half of those answered, crowd-eye; otherwise if more than half use only a part of the blot, detail-hunter; otherwise if at least 3 in 4 are your own and at least half are detailed (4 or more words), far-eye; otherwise fresh-eye.
| Field | Required | What it holds |
|---|---|---|
task | yes | Always read-blots. |
answers | yes | 5 lines, blot 2 | a part of the blot | a pair of boots at the bottom, or blot 5 | skipped. Answers are up to 80 characters. |
tally | yes | 5 lines, B1 | usual (bat) | whole | 2 words | second look: scale - change its size or B5 | skipped, then the counts: answered 4 | usual 1 | own 3 | part 3 | whole 1 | detailed 3. |
retry_note | no | Only on the page's single reformat retry. |
The reply is one JSON object:
{"task": "read-blots", "verdict": "fresh-eye", "headline": "...", "blots": [{"n": 1, "kind": "own", "reading": "...", "second_look": "...?"}, ...], "thread": "...", "closing": "..."}
| Field | What it holds |
|---|---|
verdict | crowd-eye, detail-hunter, far-eye or fresh-eye, by the rule above. |
headline | The verdict in plain words, at most 16 words. |
blots | 1 entry per answered blot, in order. n is the blot number; kind is usual or own, copied from the tally; reading at most 25 words; second_look a question from the blot's angle, at most 22 words. |
thread | What the answers share, to the person as "you", at most 40 words. |
closing | One sentence restating the verdict and inviting a second look, at most 20 words. |
The page then checks the reply (BlotKit.check) and lists any disagreement under "The page's check".

Build the input yourself
Load the engine in node (global.window = global; require("./blotkit.js")), then:
const K = BlotKit;
const built = K.buildInput(K.form({ seed: 7, answers: [
{ text: "a kite caught in a tree", where: "whole" }, { text: "a comb", where: "part" },
{ text: "a tuba" }, { text: "" }, { text: "two foxes arguing" } ] }));
built.input.tally; // the page's 5 tally lines + the counts line
const wire = K.toWire(built.input); // POST this to /estimate and /run
// then: const reply = K.normalize(K.parseReply(job.output.output));
// built.facts.verdict // the verdict the page's rule gives
// K.check(reply, built).notes // the page's re-check of the reply
// K.md(built, reply, "my set") // the set as Markdown

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.

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":"fold-and-look"}' | jq -r '.data.token')
# a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
TOKEN = ""
TOKEN = api("POST", "/guest", {"slug": "fold-and-look"})["token"]
// a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
TOKEN = "";
TOKEN = (await api("POST", "/guest", { slug: "fold-and-look" })).token;
// inside main: a guest token (enough for /me and /estimate); a run needs your personal token
token = ""
g, err := api("POST", "/guest", map[string]string{"slug": "fold-and-look"}, nil)
if err != nil { panic(err) }
token = g["token"].(string)
// inside main: a guest token (enough for /me and /estimate); a run needs your personal token
token = "";
token = api("POST", "/guest", Map.of("slug", "fold-and-look"), null).get("token").asText();
# a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
TOKEN.replace("")
TOKEN.replace(api("POST", "/guest", { slug: "fold-and-look" })["token"])
// a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
$TOKEN = "";
$TOKEN = api("POST", "/guest", ["slug" => "fold-and-look"])["token"];
// a guest token (enough for /me and /estimate); a run needs your personal token from /tokens.html
Api.Token = "";
Api.Token = (await Api.Call("POST", "/guest", new { slug = "fold-and-look" }))!["token"]!.GetValue<string>();
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}'
me = api("GET", "/me")
print(me["subject_type"], me.get("credits"))
const me = await api("GET", "/me");
console.log(me.subject_type, me.credits);
me, _ := api("GET", "/me", nil, nil)
fmt.Println(me["subject_type"], me["credits"])
JsonNode me = api("GET", "/me", null, null);
System.out.println(me.get("subject_type") + " " + me.get("credits"));
me = api("GET", "/me")
puts [me["subject_type"], me["credits"]].inspect
$me = api("GET", "/me");
echo $me["subject_type"], " ", $me["credits"] ?? "", "\n";
var me = await Api.Call("GET", "/me");
Console.WriteLine($"{me!["subject_type"]} {me["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": "read-blots", "answers": "blot 1 | the whole blot | a bat
...", "tally": "B1 | usual (bat) | whole | 2 words | second look: scale - change its size
..."}
# - see the field table
api POST /estimate "$(cat input.json)" | jq '.data | {hold_credits, min_credits, model, model_alias, markup_bps, warnings}'
inp = json.load(open("input.json")) # {"task": "read-blots", "answers": "blot 1 | the whole blot | a bat
...", "tally": "B1 | usual (bat) | whole | 2 words | second look: scale - change its size
..."}
# - see the field table
est = api("POST", "/estimate", inp)
print(est["hold_credits"], est["min_credits"], est["model"], est.get("warnings"))
import { readFileSync } from "node:fs";
const input = JSON.parse(readFileSync("input.json", "utf8")); // {task: "read-blots", answers, tally} (see the field table)
const est = await api("POST", "/estimate", input);
console.log(est.hold_credits, est.min_credits, est.model, est.warnings);
raw, _ := os.ReadFile("input.json") // add "os" to the imports
var input map[string]any
json.Unmarshal(raw, &input)
est, _ := api("POST", "/estimate", input, nil)
fmt.Println(est["hold_credits"], est["min_credits"], est["model"])
Map<String, Object> input = M.readValue(new java.io.File("input.json"), Map.class);
JsonNode est = api("POST", "/estimate", input, null);
System.out.println(est.get("hold_credits") + " " + est.get("min_credits") + " " + est.get("model"));
input = JSON.parse(File.read("input.json"))
est = api("POST", "/estimate", input)
puts [est["hold_credits"], est["min_credits"], est["model"]].inspect
$input = json_decode(file_get_contents("input.json"), true);
$est = api("POST", "/estimate", $input);
echo $est["hold_credits"], " ", $est["min_credits"], " ", $est["model"], "\n";
var input = JsonNode.Parse(File.ReadAllText("input.json"))!;
var est = await Api.Call("POST", "/estimate", input);
Console.WriteLine($"{est!["hold_credits"]} {est["min_credits"]} {est["model"]}");
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 fold-and-look:<task>:<inputHash>:a<attempt> (the one task is read-blots), 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="fold-and-look:read-blots:$(shasum -a 256 input.json | cut -c1-16):a1"
JOB=$(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
