space.launches

Upcoming or recent orbital rocket launches from The Space Devs' Launch Library 2 — the live manifest behind most launch-tracking apps. `when`=upcoming (default) or previous. Optional `search` filters by rocket, provider, or mission text (e.g. "Starship", "SpaceX", "Artemis"). Each launch: name, status (Go/TBD/Success/Failure), NET launch time + window (UTC), launch provider, rocket configuration, pad + location, mission name/type/orbit/description, and whether a webcast is live. Real-time data agents can't get from training. Public CC-BY data (attribute The Space Devs).

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/space/launches?when=upcoming&search=example&limit=10&offset=0'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/space/launches?when=upcoming&search=example&limit=10&offset=0' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/space/launches?when=upcoming&search=example&limit=10&offset=0'
