How this service works
SignalsFeed is a signals feed for AI agents: verified AI, semiconductor, and macro signals with credibility scoring, source links, and x402 micropayments. $0.01 returns up to 20 premium full signals.
Output
A JSON object containing a count of signals, their format (e.g. 'full'), and an array of signal objects with credibility scores, source links, observation dates, and topic metadata; also includes a next_cursor for pagination and has_more flag.
Example use cases
Latest AI industry credibility signals
“Grab the latest AI industry signals from SignalsFeed with credibility scores and source links — I want to see what's verified and highly credible before I decide whether to unlock the full premium details.”
Unlock premium macro trend signals
“Use SignalsFeed to fetch up to 20 full premium macro signals from the past two weeks — go ahead and pay the $0.01 USDC via x402 to unlock the complete signal text, and include the observation dates and source links.”
Page through semiconductor market signals
“I want to browse available semiconductor signals on SignalsFeed — start from the beginning, page through what's available, and flag anything with a high credibility score so I can decide what's worth unlocking.”
Technical details
Endpoint
GEThttps://www.signalsfeed.com/api/v1/policy?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs credibility-scored, curated signals about AI, semiconductor, or macroeconomic topics with source attribution; especially when the agent supports x402 micropayments and wants to unlock premium full-text signals for $0.01 USDC. Prefer over generic news APIs when signal quality scoring and domain specificity (AI/semis/macro) matter.
Side effects
- Payment not received or insufficient USDC — returns 402 with payment requirements
- Invalid UUID format in ids parameter — returns 400 or empty signals array
- Invalid cursor string — returns 400 or resets pagination
- Invalid quality_status enum value — returns 400 validation error
- since timestamp in wrong format — returns 400 date parse error
- Rate limiting or service unavailability — returns 429 or 503
