How this service works
Use this when you need the current state of AI progress in one call: the latest reading of 129 public series (frontier benchmark scores GPQA/HLE/ARC-AGI/METR, Epoch compute trends, AGI odds on Polymarket/Manifold/Kalshi, model pricing, AI stocks and crypto, energy, space, robotics, biomed, research output). One JSON row per series: latest and previous value with dates, % change, signal quality, source URL. Free 3-row sample at /preview.
Output
A JSON object containing a snapshot_id, run timestamp, and an array of up to 129 source rows. Each row includes: a series ID, domain, metric name, unit, latest value with date, previous value with date, percent change vs previous, number of historical points, signal quality rating, confidence level, data access type, and source URL. Also includes a list of all covered domains and metadata like schema version and counts of OK sources.
Example use cases
AGI prediction market monitoring
“What are the current AGI odds across Polymarket, Manifold, and Kalshi, and how much have they moved since the last reading?”
Frontier benchmark score briefing
“Give me a quick briefing on where the latest frontier AI benchmark scores stand — GPQA, HLE, ARC-AGI, and the METR task-completion horizon — and how much each has changed.”
AI investment thesis data pull
“I'm putting together an AI investment memo — can you grab the latest Accelerometer snapshot so I have current numbers on AI compute trends, model pricing, AI stocks, and research output all in one place?”
Technical details
Endpoint
GEThttps://x402-accelerometer-feed.fly.dev/ai-progress/latestWhen to prefer
Choose this endpoint when you need a broad, multi-domain snapshot of AI progress in a single call rather than querying individual data sources separately. It is ideal for dashboards, briefings, investment research, or automated monitoring workflows that need heterogeneous AI metrics (benchmarks, compute, markets, pricing) normalized into a consistent per-series format. Prefer historical sibling endpoints if you need a past date's snapshot rather than the latest.
Side effects
- Payment not attached or insufficient — returns HTTP 402 requiring x402 USDC payment
- Service temporarily unavailable on fly.dev infrastructure — returns 5xx error
- Some upstream data sources may be stale or unavailable, reflected in n_sources_ok being less than n_sources
- Malformed request may return 4xx if unexpected query parameters are sent
