Nanobridge: 1 million free signup credits for catalog-model API testing; no card required
An October 20 developer sponsor video led to Nanobridge’s official signup offer: one million provider credits without a card. Its gateway serves catalog models through OpenAI- and Anthropic-compatible API shapes. Compatibility does not mean free OpenAI or Claude models.
How to claim this perk
Follow these steps through Nanobridge.
Access: Direct application
- 1
Open the official registration page; no creator code is needed for the published one-million-credit allowance.
- 2
Check the awarded balance and expiry in the developer console.
- 3
Create a key and select a supported model after checking its credit rate.
Who can apply?
- New signup allowance. Credits are Nanobridge usage units, not $1 million or a guaranteed one million tokens on every model.
- Model rates differ and all chat models draw from one credit pool. Hunyuan 3D uses per-successful-submission billing; inspect the account’s current costs before running requests.
- The homepage does not specify the free grant’s expiry. The separate paid packs’ 30-day validity must not be assumed to be the free grant’s rule.
