AI API Router Directory

Meta's developer site now fronts a single Meta Model API (documented at dev.meta.ai) covering Muse and Llama models: Muse Spark 1.3 for agentic and coding work, Muse Glimmer as an open-weight model for local agents, Muse Image, Muse Voice Transcribe, and the Llama 4 and Llama 3 families. The only unit prices published on the official pages that returned content are Muse Voice Transcribe at $0.18/hour for streaming transcription and Muse Image at $0.01/image; no per-million-token Llama pricing and no free-credit figure appeared there, and the llama.developer.meta.com documentation domain returned no fetchable content on 2026-09-16.

No free tier or credit is stated on the official Meta pages that returned content (checked 2026-09-16); the llama.developer.meta.com documentation domain returned no fetchable content, so no allowance is claimed.

Zylo API provides a unified OpenAI-compatible gateway to models from Anthropic, OpenAI, Google, and more with zero token markup. Billing is based on base per-token rates deducted from a prepaid balance. A flat platform fee applies when adding credits.

No public free-tier information found in the source reference; treat free-tier availability as unverified rather than confirmed absent.
