How this service works
Pay-per-call (x402) market-data + research API for autonomous agents. Paid endpoints return HTTP 402 with an x402 v2 payment challenge; pay in USDC on Base with any x402-aware client.
Output
A JSON envelope containing market signal forecasts and research data. The exact shape of the response object is not fully specified in the schema, but it returns structured forecast/signal fields relevant to autonomous agent decision-making, gated behind a $0.05 USDC x402 payment settled on the Base network.
Example use cases
Autonomous trading agent signal refresh
“Grab the latest market signal forecasts from SundayFactoryX for my trading agent — pay the micropayment in USDC on Base and return the JSON results.”
Scheduled research data pull for portfolio bot
“Every hour, fetch fresh signal forecasts from SundayFactoryX and feed them into my portfolio monitoring bot; handle the $0.05 USDC x402 payment automatically.”
On-demand forecast check before trade execution
“Before I execute this trade, check what the current SundayFactoryX signal forecasts say and give me a summary — pay whatever is needed on Base to unlock the data.”
Technical details
Endpoint
GEThttps://api.sundayfactoryx.com/v1/signals/forecasts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your autonomous agent needs market signal forecasts on a pay-per-call basis without committing to a subscription, especially when the agent is x402-aware and can settle micropayments in USDC on Base. It is well-suited for infrequent or event-driven forecast lookups where cost efficiency per call matters. Prefer alternatives if you need high-frequency polling (cost adds up at $0.05/call), if you require guaranteed schema stability, or if your agent cannot handle x402 payment flows.
Side effects
- HTTP 402 returned if payment challenge is not satisfied — agent must complete x402 v2 USDC payment on Base before data is released
- Invalid or missing format parameter may result in unexpected response envelope structure
- Payment failure or insufficient USDC balance on Base will block access to forecast data
- Network or provider downtime may result in 5xx errors with no forecast data returned
- Stale or cached data may be returned if upstream market data provider is delayed
