REST · OpenAPI 3.1

API kontrak pemerintah, dengan paritas penuh.

Every screen on Sell to State is backed by a documented REST endpoint under /api/v1. Search, drill into a buyer or supplier, export CSV, and keep saved lists — with one API key and the same paywall the MCP server and CLI share.

Full reference → MCP server

# Panduan cepat 60 detik

# 1. Create a key in the dashboard
#    Account → API keys
# 2. Verify it
curl -s https://app.selltostate.com/api/v1/whoami \
  -H "x-api-key: sts_xxxxxxxx"

# 3. Search
curl -s "https://app.selltostate.com/api/v1/search\
?scope=tenders&q=cybersecurity" \
  -H "x-api-key: sts_xxxxxxxx"

Same key works for the MCP server and the selltostate CLI.

Autentikasi & paywall 402

Two credential types resolve to one entitlement check. Humans and backends send an API key as x-api-key: sts_…. Autonomous agents self-register over RFC 7591 DCR and present Authorization: Bearer client:<id>.

Until your subject has an active subscription, every data call returns 402 with a payment_link (humans) and a machine_payment affordance (agents can pay off-session via POST /api/v1/pay and continue without a browser). GET /api/v1/whoami is the exception — it returns 200 with active:false so you can decide to pay before doing work.

Plan caps: monthly and annual = 5,000 rows/page; the 3-day pass = 10,000 rows in total. Rate limit: 120 data calls/min per credential (faceted search has its own 300/min budget). Saved lists and saved searches are owner-scoped — they require a user x-api-key; an OIDC client token gets 403.

Endpoint.

All under /api/v1. Full params, schemas and "Try it" live in the reference.

GET /api/v1/whoami Autentikasi + hak akses + scope. Mengembalikan 200 active:false (bukan 402) untuk key yang valid tapi belum berlangganan — periksa sebelum digunakan.
GET /api/v1/search Pencarian Typesense berfaset dalam satu scope (tenders | buyers | suppliers | sectors): hasil + hitungan faset + paginasi.
GET /api/v1/awards Baris pemenang tender berpaginasi dan bisa difilter, diurutkan berdasarkan nilai. CSV tersedia di /api/v1/awards.csv.
GET /api/v1/buyers/{slug} Detail pembeli (instansi): ringkasan, tren belanja tahunan, sebaran sektor, pemasok utama.
GET /api/v1/suppliers/{slug} Detail pemasok: ringkasan, tren kemenangan tahunan, sebaran sektor, pembeli utama.
GET /api/v1/sectors/{slug} Detail sektor: ringkasan, tren tahunan, mitra aktif (?kind=buyers|suppliers).
GET /api/v1/tenders/{id} Satu data pemenang berdasarkan id numerik atau id tender publik, beserta pemenang terkait.
CRUD /api/v1/lists* Daftar pemenang tender tersimpan. Terbatas pada pemilik — memerlukan x-api-key pengguna.
CRUD /api/v1/saved-searches* Pencarian tersimpan. Terbatas pada pemilik — memerlukan x-api-key pengguna.

Contoh.

Python — mencari pemenang tender

import requests

H = {"x-api-key": "sts_xxxxxxxx"}
r = requests.get(
    "https://app.selltostate.com/api/v1/search",
    params={"scope": "tenders", "q": "cybersecurity", "year_min": 2023},
    headers=H,
)
if r.status_code == 402:
    print("subscribe:", r.json()["payment_link"]); raise SystemExit
data = r.json()
print(data["found"], "matches")
for hit in data["hits"]:
    print(hit)

Node — detail pembeli + ekspor CSV

const H = { "x-api-key": process.env.STS_API_KEY };

const buyer = await fetch(
  "https://app.selltostate.com/api/v1/buyers/ministry-of-education",
  { headers: H },
).then((r) => r.json());
console.log(buyer.buyer, buyer.yearly);

// Stream the entitlement-capped CSV
const csv = await fetch(
  "https://app.selltostate.com/api/v1/awards.csv?supplier=ACME",
  { headers: H },
).then((r) => r.text());

Daftar tersimpan (key pengguna)

# Create a list, add a tender, read it back
LID=$(curl -s -X POST https://app.selltostate.com/api/v1/lists \
  -H "x-api-key: sts_xxxxxxxx" -H "content-type: application/json" \
  -d '{"name":"Cyber FY24"}' | jq -r .id)

curl -s -X POST https://app.selltostate.com/api/v1/lists/$LID/items \
  -H "x-api-key: sts_xxxxxxxx" -H "content-type: application/json" \
  -d '{"tender_no":"MOE000ETT24300001"}'

Poll for new tenders.

A job in your scheduler, Zapier or n8n can ask for the tenders added to Sell to State since its last run. Keep the time of each run and send it as added_after. Remove duplicates by slug. 

LAST=$(cat last_run 2>/dev/null || echo 0)
NOW=$(date +%s)
curl -s "https://app.selltostate.com/api/v1/search?scope=tenders&country=united-kingdom&q=software&sort=added_desc&added_after=$LAST&per_page=50"   -H "x-api-key: sts_xxxxxxxx"
echo "$NOW" > last_run
ParamValues
sortadded_desc (newest in Sell to State first), published_desc (newest publish date first), deadline, relevance
added_afterUnix seconds. Only tenders added after this time.
published_days1, 7, 30, 90, 365

The search limit is 300 calls a minute per key. A poll every 5 minutes or more is enough for tenders. Integrations
