Market note · 23 September 2026
A soft day as coverage climbs and three plans cut hard
The Agentic Economy Price Index closed the 23 September observation at 100.455, down from 100.492 on 22 September (about −0.037% day-over-day; rounds to about −0.04%). Over seven days the headline is still near flat (about +0.03%); over 30 days it is up +0.23%. Like-for-like coverage climbed — 8,899 pairs, from 8,793 the day before. These levels and pair counts are from aepi-ledger-v2; do not stitch them to older market notes that used the prior ledger (the 21 and 22 September notes sat near 7.5–7.7k pairs). Pulse released 2026-09-23T14:55:19Z (release_id 45, aepi-ledger-v2). 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 | 100.455 | 8,899 | +0.23% |
| Agents | 100.402 | 2,329 | +0.05% |
| MCPs | 100.411 | 4,682 | +0.16% |
| Infrastructure | 100.426 | 1,692 | +0.64% |
| APIs | 101.345 | 328 | +1.28% |
| Platforms | 100.168 | 1,283 | +0.56% |
| Frameworks | 100.620 | 81 | 0.00% |
| Skills & plugins | 108.304 | 37 | +1.22% |
Levels and pair counts are from aepi.ai (pulse + index.csv), not a third-party embed. APIs remain a strong 30-day riser in this release set. Skills & plugins print a same-window lift on a very thin cohort (37 pairs) — low confidence by design. Frameworks are flat on 30 days on a thin cohort (81 pairs). Agents soft day-over-day (about −0.12% from the CSV) while MCPs are near flat.
What published
Published genuine repricings for the day (held = 298; zero currency-only moves filtered). Three published:
- needle_agents Needle Pro (pro): $199 → $69/agent/mo (−65.3%)
- finbridge Pro (pro): $30.00 → $20.00/mo (−33.3%)
- eccentex_adaptive_document_man Customer Service Cloud (team_sme): $224 → $149/user/mo (−33.5%)
The standout cut is Needle Pro — down about two-thirds per agent — plus FinBridge Pro and Eccentex Customer Service Cloud each down about a third. Net still a soft headline: three loud cards do not make a loud index when most of the chain is quiet.
Method in one line
AEPI only counts a price change when the same plan from the same provider is observed at a new standing price — live daily at aepi.ai and agentery.com/aepi. Free CSVs and MCP at aepi.ai. Not investment or pricing advice.
Figures from aepi.ai pulse + index.csv for observation day 2026-09-23 (release 45, published 07:55 PT / 14:55 UTC). Prefer aepi.ai over the agentery.com/aepi embedded payload on any disagreement.
