Market note · 25 September 2026
Coverage rebounds as End of Life lifts Starter
The Agentic Economy Price Index closed the 25 September observation at 100.46, a hair up from 100.458 on 24 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 +0.002% vs 18 September); over 30 days it is up +0.25%. Like-for-like coverage rebounded — 8,900 pairs, from 8,784 the day before (+116). 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 drafts sat near 7.5–7.7k pairs). Pulse released 2026-09-25T05:30:42Z (release_id 51, 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.
Agents and MCPs, not one blend
| Scope | Level | Pairs | 30d |
|---|---|---|---|
| All | 100.46 | 8,900 | +0.25% |
| Agents | 100.403 | 2,333 | +0.05% |
| MCPs | 100.419 | 4,705 | +0.21% |
| Infrastructure | 100.428 | 1,677 | +0.64% |
| APIs | 101.345 | 331 | +1.28% |
| Platforms | 100.17 | 1,265 | +0.56% |
| Frameworks | 100.62 | 81 | 0.00% |
| Skills & plugins | 108.304 | 27 | +1.22% |
Levels and pair counts are from aepi.ai (pulse + index.csv), not a third-party embed. Coverage recovered across most delivery scopes after yesterday’s thinner day; Frameworks and Skills & plugins still sit on thin cohorts (81 and 27 pairs) — low confidence by design. APIs remain a strong 30-day riser in this release set and regained pairs (331, from 306). Agents and MCPs each edged up a hair day-over-day on the CSV.
What published
Published genuine repricings for the day (held = 332; zero currency-only moves filtered). Five published:
- endoflife Starter (individual): $79/mo → $89/mo (+12.7%)
- mailchimp Standard (pro): €17.59/month → €17.68/month (+0.5%)
- greminders_mcp AI Note Taker Essentials (individual): €43 (EUR) / User per Month → €44 (EUR) / User per Month (+2.3%)
- greminders_mcp 320 SMS (pro): €46 (EUR) / month → €47 (EUR) / month (+2.2%)
- greminders_mcp Professional (pro): €64 (EUR) / month → €65 (EUR) / month (+1.6%)
The loud card is End of Life Starter, up about an eighth. GReminders prints three small euro bumps on Note Taker Essentials, 320 SMS, and Professional; Mailchimp Standard ticks half a percent. Net still a flat headline: five quiet-to-modest cards do not make a loud index when most of the chain is quiet.
