A wider sweep past the earlier shortlist surfaced 46 additional GPT-5.6 Luna provider and listing candidates (Codex excluded), assessed as of 2026-09-03. Each was graded on access type, free-quota evidence and coding/API fit; the count of newly verified unlimited free APIs in this batch is zero.
Faceb.ai is the strongest new lead: its Luna page grants 30,000 free tokens every day after signup and advertises chat + API, but the evidence never states the daily allowance can be spent through API calls — API eligibility unresolved.

CloudAxis is a verified free coding product, not a gateway: Luna powers Auto Mode on its Free plan with hard monthly caps, and the provider explicitly says no API keys.

Free claims collapse under provider-owned evidence: Kilo Gateway's "free/no wallet" line is directory-only
jishie.com, Respan's $0 listing
respan.ai and iMini's free quota
imini.com lack a verified usable quota or API path.
The strict conclusion holds: a provider-owned, recurring, no-payment / no-credit GPT-5.6 Luna API quota for coding remains unverified — a model page alone never proves a working or free endpoint.
Data: 46 additional GPT-5.6 Luna provider/service candidates from the expanded search, one row each, assessed 2026-09-03. "Pages" counts supporting evidence pages per candidate. Tiers are assigned from each row's verification status. Codex-related offers were excluded by request; long status texts are shortened in the chart tooltips only.
