Bolt

In Bolt a keyed call to AstroWay works only from a server function. The Bolt preview runs in a real browser with real CORS, so a request to api.astroway.info from the page will not go through, and a key in VITE_* would end up in the bundle as well. A server function runs on Bolt’s servers and reads the key from the project’s secrets.

1. Database and key

1. Server functions and secrets in Bolt are tied to a Bolt Cloud database. If the project has none yet, ask Bolt to add one.
2. Create a Server only AstroWay key scoped to chart with a budget, as described in A key for an automation. The budget stops a stranger’s client that calls your function at the number you set.

2. The prompt

prompt

Create a server function named big-three. It reads the secret
ASTROWAY_API_KEY and POSTs the JSON body { date, time, timezone, latitude,
longitude } to https://api.astroway.info/v1/chart with the header
"X-Api-Key: <secret>". Never call api.astroway.info from the browser and
never put the key in a VITE_ variable.

The response is { ok: true, data: {...} } or { ok: false, error: { code,
message } }. On error return the error object with the same HTTP status.
On success return { sun, moon, rising, offset_used } where each sign is
SIGNS[Math.floor(longitude / 30)] with SIGNS = Aries, Taurus, Gemini,
Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius,
Pisces; sun and moon come from data.planets entries named "Sun" and
"Moon", rising from data.houses.ascendant, offset_used from
data.input.timezoneOffset.

Then add a form with date, time, an IANA time zone (default Europe/Kyiv),
latitude and longitude, and show the three signs from the function.

Server functions in Bolt Cloud run in the same environment as Supabase Edge Functions, so the finished file is on Supabase Edge Function. If Bolt generated something else, paste that file.

3. The secret

Bolt asks you to add ASTROWAY_API_KEY itself once the function is ready. By hand: in the project’s top menu click the database icon → Secrets and add a secret with that name. Only the project owner sees secrets, and in a team account co-owners and team admins too.

4. Check it

Enter 1990-05-15, 14:30:00, Europe/Kyiv, 50.45, 30.52. The right answer: Sun Taurus, Moon Capricorn, rising Virgo, offset 4. An offset of 3 means the app works out the offset itself instead of sending the zone name. One calculation costs 20 credits; the function’s call logs are in the database settings under Logs.

Tip

Ready prompts for other apps, and the rules to paste before any of them, are on Prompts for AI builders.

Note

Checked on 2026-11-07: the function from Supabase ran locally in Deno against AstroWay production, with the answer above. The steps in the Bolt interface follow its help centre and were not carried out in this check.
