  title: Tigris Object Storage (S3-Compatible) Buckets API
  description: 'Specification of the Tigris globally distributed object storage API. Tigris is compatible with the AWS S3 API, so the standard AWS S3 SDKs, tools, and libraries work unchanged against the Tigris endpoint at https://t3.storage.dev (the legacy host fly.storage.tigris.dev still resolves). Requests are authenticated with AWS Signature Version 4 using a Tigris access key id (tid_...) and secret access key (tsec_...). This document models the documented, supported subset of the S3 surface: bucket management, object CRUD, multipart upload, object tagging, storage-class tiering, and the path-style operations that back presigned URLs. The companion AWS IAM-compatible API is served at https://iam.storage.dev. Tigris is region-agnostic - use region "auto".'

      description: AWS Signature Version 4 request signing. Clients sign each request with a Tigris access key id (AWS_ACCESS_KEY_ID=tid_...) and secret access key (AWS_SECRET_ACCESS_KEY=tsec_...); the signature is carried in the standard Authorization header (or query string for presigned URLs). Use service name "s3" and region "auto". Any AWS SDK / SigV4 signer produces a compatible signature.
