Free LLM API Hub
A continuously reverified, machine-readable dataset of free-tier and trial-credit language model and adjacent AI APIs, with every entry dated, sourced to the provider's own documentation.
Rather than a one-time blog-post list, the project treats its data as a maintained dataset: every entry carries a last-verified date and a link to the provider's own documentation, a computed freshness badge grades the oldest re-verified entry against a 90-day service-level target, and every change runs an integrity check that reopens each provider's own source link, so a broken link surfaces as an early signal that something changed. Entries the maintainers could not independently confirm are marked as unconfirmed rather than presented as fact.
Coverage centers on free text-generation APIs but also includes adjacent free or trial-credit APIs for images, speech, embeddings, reranking and OCR, with the canonical data kept in a schema-validated JSON file from which the README, badge and companion site are all generated, so they cannot silently drift apart. The project explicitly disclaims any affiliation with the providers it lists.
