⁠Decimer (v2) Server API

DECIMER chemical structure image-to-SMILES service via FastAPI (including reaction-based images).
Docs and source: https://github.com/DocMinus/DecimerServerAPI⁠

What’s new in V1.2.1: Hardened, MCP-compatible endpoints. Fully back compatible to V0.2.1

⁠Tags

• latest = newest release
• 1.2.1, 0.2.1, etc. = fixed release tags

For reproducible deployments, pin a version tag (for example :1.2.0) instead of :latest.

⁠API notes

• Main endpoint: POST /image2smiles/
• Python client:
  • call_image2smiles(...) -> returns SMILES string (backward compatible)
  • call_image2smiles_with_meta(...) -> returns full metadata payload

⁠Platform

linux/amd64 image (compatible with Windows/Linux/macOS, including Apple Silicon).

If you want architecture-native or custom builds, build from source using the GitHub repo above.
