Subscribing to an Orbis API

Subscribing gives you an API key for authenticated access. Most APIs include a free tier — subscribe first, then use your key.

Step 1: Find the API slug

If you don't know the slug, use the browse-orbis-apis skill first:

curl "https://orbisapi.com/api/marketplace/apis?search=<query>&limit=5" | python3 -c "
import json, sys
apis = json.load(sys.stdin).get('apis', [])
for a in apis:
    print(a['slug'], '-', a['shortDescription'])
"

Step 2: Subscribe (via MCP — Recommended)

If you have the Orbis MCP configured, simply ask:

"Subscribe me to the [API name] API on Orbis"

The MCP call_api tool handles subscription automatically.

Step 3: Subscribe (via REST API)

Requires a wallet address (from user) and Orbis account:

# 1. Check free tier details
curl "https://orbisapi.com/api/marketplace/apis/<slug>"

# 2. Subscribe
curl -X POST "https://orbisapi.com/api/subscriptions" \
  -H "Content-Type: application/json" \
  -H "x-wallet-address: <USER_WALLET_ADDRESS>" \
  -d '{"apiSlug": "<slug>", "tier": "free"}'

# Response includes your API key:
# { "key": "orbis_...", "tier": "free", "callsRemaining": 100 }

Step 4: Store the API Key

Save the returned key for use in call-orbis-api:

orbis_xxxxxxxxxxxx

Subscription Tiers

Tier	Description
`free`	Free calls per month (varies by API)
`paid`	Pay per call via Stripe (credit card)
`x402`	Pay per call in USDC on Base — no subscription needed

Next Steps

Use the call-orbis-api skill to make calls using your new key.
