Quickstart · cURL

Probe Orrery from the shell

Useful for debugging, shell pipelines, language-agnostic integrations, and answering 'is the API alive?' Every endpoint accepts cURL and returns the same envelope shape as the SDK quickstarts.

Replay with X-PAYMENT (after enforcement)

When payment enforcement is enabled, paid endpoints return HTTP 402 with a JSON challenge. Settle on Base via your wallet, then attach the proof:

# 1. Probe the price.
curl -i https://orrery.me/api/x402/v1/brief/today | head -20
# HTTP/1.1 402 Payment Required
# X-PAYMENT-REQUIRED: {"scheme":"x402-onchain","network":"base",...}

# 2. Settle on Base via your x402-compliant wallet, then replay:
curl -s https://orrery.me/api/x402/v1/brief/today \
  -H "X-PAYMENT: <on-chain settlement proof>" | jq '.meta.payment_status'
# "settled"

See the Coinbase x402 docs for the settlement format. Orrery is wallet-agnostic.

Tips

• All endpoints set permissive CORS — you can call them from a browser script too.
• jq is your friend for the envelope: .data is the payload, .meta has the price, source, and freshness.
• The HTTP rate-limit is 60 req/min/IP across all paid endpoints. The 429 response carries Retry-After.
