Market note · 22 September 2026
A flat day as coverage climbs and one starter lifts
The Agentic Economy Price Index closed the 22 September observation at 100.348, a hair up from a revised 100.346 on 21 September (about +0.002% day-over-day; the public card rounds to flat / 0.00%). Over seven days the headline is still near flat (about +0.003%); over 30 days it is up +0.20%. Like-for-like coverage climbed — 7,738 pairs, from 7,708 the day before. Pulse released 2026-09-22T05:31:11Z (release_id 42, aepi-ledger-v1). Data by Agentery; free series live at aepi.ai.
Keep the scale honest: this is a market whose headline barely moves. Most listings never reprice on a given day, which is why small chained moves and the occasional large published reprice are the useful read. Agentery’s continuity log marks today’s priced-observation chain as not intact (some listings went blank after a priced run); that thins like-for-like pairing for those names even when the printed index still advances.
Agents and MCPs, not one blend
| Scope | Level | Pairs | 30d |
|---|---|---|---|
| All | 100.348 | 7,738 | +0.20% |
| Agents | 100.701 | 2,064 | +0.17% |
| MCPs | 100.377 | 4,228 | +0.24% |
| Infrastructure | 99.526 | 1,286 | +0.09% |
| APIs | 101.808 | 226 | +1.65% |
| Platforms | 98.953 | 995 | −0.14% |
| Frameworks | 99.236 | 65 | −1.45% |
| Skills & plugins | 98.905 | 34 | +0.54% |
Levels and pair counts are from aepi.ai (pulse + index.csv), not a third-party embed. APIs remain the strongest 30-day riser in this release set. Frameworks stay soft on a thin cohort (65 pairs). Platforms are still slightly underwater on 30 days. Skills & plugins hold a same-window lift on a very thin cohort (34 pairs) — low confidence by design.
What published
Published genuine repricings for the day (held = 0; four currency-only moves filtered). One published:
- logistify_ai Starter (individual): $249 → $299/mo (+20.1%)
The only published card is a starter-plan rise of about a fifth on Logistify (AI Agents for Supply Chain / dock scheduling). Net still a flat headline: one loud card does not make a loud index when most of the chain is quiet.
Method in one line

Figures from aepi.ai MCP + index.csv for observation day 2026-09-22 (release 42, published 22:31 PT / 05:31 UTC). Prefer aepi.ai over the agentery.com/aepi embedded payload on any disagreement.
