How this service works
Buy the next N Polymarket weather-signal(s) for a city (bundle prepay, count ≥ 2, $0.01–$7.00). Returns a Bearer receipt for /v1/signals. Nonce binds (payer, citySlug, count).
Output
A Bearer receipt token that can be passed to GET /v1/signals to redeem the purchased weather signal(s), along with a nonce binding the payer, city slug, and signal count. The receipt confirms the prepaid bundle and authorizes future signal retrieval.
Example use cases
Example prompt
“Buy me a bundle of 4 Polymarket weather signals for Istanbul on Isocast so I can start pulling forecasts — prepay for the whole pack now.”
Technical details
Endpoint
POSThttps://api.isocast.dev/v1/subscribeWhen to prefer
Use this endpoint when you need to prepurchase multiple Polymarket weather signal forecasts for a specific city in a single prepaid bundle. It is the only way to obtain a Bearer receipt for /v1/signals on Isocast. Prefer this over single-signal alternatives when you need 2 or more signals and want to lock in a bundle price upfront.
Side effects
- count < 2 — minimum bundle size not met, request rejected
- total spend below $0.01 USDC minimum — rejected
- invalid or unrecognized city slug — returns error, use GET /v1/cities to enumerate valid slugs
- payment failure or insufficient USDC balance — transaction not completed
- nonce reuse — same payer/citySlug/count combination already used
- malformed request body — missing required fields city or count
