Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 24 Dec 2026 as of our check on 8 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE2 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of gethologram.ai controls every word below.

Discovery

What this endpoint is, in a form a machine can bind to without reading prose.

Examples it gives

curl https://gethologram.ai/openapi.json

Health

Is the endpoint up, and which byte sources are up behind it.

getHealthgetSourceHealth

Examples it gives

curl https://gethologram.ai/api/hub/health

Models

Find a model and read its files, in Hugging Face's shape. This is the dialect every Python client already speaks.

listModelsgetModelgetModelAtRevisionlistModelRefslistModelFileslistModelFilesUndergetModelSizegetXetReadToken

Examples it gives

curl 'https://gethologram.ai/api/models?search=qwen&filter=gguf&limit=5'
export HF_ENDPOINT=https://gethologram.ai && hf download Qwen/Qwen3-0.6B

Files

Turn a model file into a URL that is up right now, together with the SHA-256 it must have.

Examples it gives

curl -sI https://gethologram.ai/Qwen/Qwen3-0.6B/resolve/main/config.json
curl -s https://gethologram.ai/Qwen/Qwen3-0.6B/resolve/main/SHA256SUMS | sha256sum -c

Objects

The content-addressed floor under every dialect. An object is named by the BLAKE3 of its bytes, so its answer can be cached forever.

getCapabilitieslistModuleslistObjectspublishObjectgetObject

Examples it gives

curl https://gethologram.ai/api/v1/objects/blake3:<hex>

Registry

The OCI distribution dialect: Ollama pulls, CNCF ModelPack artifacts, and the hub's own daily index. Reads are anonymous; a write is refused at the edge unless it carries the registry token that `docker login` sends, and writes are not described here because only the hub publishes.

getRegistryBaselistRegistryRepositorieslistModelTagsgetModelManifestgetModelBlob

Examples it gives

ollama pull gethologram.ai/qwen/qwen3-0.6b-gguf:Q4_K_M
oras pull gethologram.ai/qwen/qwen3-0.6b:latest

Account

The only surface that needs a person. Everything else on this endpoint is anonymous, and signing in adds nothing to it: an account exists so that a saved list, an attributed model request and a recorded interest in publishing have somewhere to live. Signing in grants no read that anonymous callers do not already have, and publishing access is an operator's decision, not a form's.

MCP

The Model Context Protocol server, for agents that bind to tools rather than to routes.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Hologram Technologies — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
