How this service works
Independent data, news and infrastructure intelligence tracking how autonomous agents discover, buy, sell and pay for useful things.
Output
A JSON object containing an array of intelligence events (each with eventId, headline, summary, freshness, and evidence tier), a nextCursor for the next poll, a count of items returned, a truncated flag, usage rights, generatedAt timestamp, and optional market movement metrics. High-resolution mode adds full evidence fields to each item.
Example use cases
Daily agent ecosystem briefing
“What's new in the machine economy since yesterday at midnight? Give me up to 10 updates from zFinia with full resolution so I can see the supporting evidence.”
Continuous x402 protocol monitoring
“I last checked the zFinia feed at cursor '2026-09-07T00:00:00.000Z' — fetch me everything new since then, up to 50 items, so I can stay current on x402 and agent payment changes.”
Weekly infrastructure change digest
“Pull the zFinia intelligence delta for the past week starting from '2026-08-31T00:00:00Z', max 25 items, so I can summarize what changed in agent discovery and payment infrastructure for my weekly report.”
Technical details
Endpoint
POSThttps://api.zfinia.com/v1/intelligence/changes-sinceWhen to prefer
Choose this endpoint when you need incremental, cursor-paginated updates on machine economy events rather than a full snapshot. It is purpose-built for polling loops where an agent already holds a prior nextCursor and wants only new material since that point, minimizing redundant data transfer and cost.
Side effects
- Missing cursor and since fields returns a validation error requiring at least one
- Stale or malformed cursor string may return an empty items array or an error
- maxItems exceeding 50 returns a schema validation error
- Network or payment failure via x402 returns HTTP 402 or 5xx
- Empty result set when no new events exist since the given cursor
