Hugging Bay API

Interactive reference (OpenAPI 3.1) openapi.json /docs llms.txt api/index.json

How can I use the Hugging Bay API to inspect a model and its files?

It depends on the record and endpoint. Read the API contract, request a model card, then inspect the individual file and availability evidence before downloading. API access returns catalog or delivery facts; it does not establish that a runtime can load a file or that the model is safe or high quality.

An API endpoint is a specific URL and method for reading or changing a defined resource. A model card summarizes a model; a file record describes an individual file. Public read endpoints return evidence; they do not run the model.

OpenAPI schema lists request and response shapes. The facts API documents public claims. For a model example, inspect the BGE small model card, its file list and recorded hashes, and its run-readiness record. These records do not establish safety or answer quality.

Key facts

Catalog vs runtime
Metadata access, file hosting and a tested load are separate checks.
Checksum
SHA-256 confirms file identity, not license permission or answer quality.
Receipts
Run evidence is scoped to one file and setup; it does not transfer to other files.

Evidence you can inspect (plain text)

  • GET /openapi.json lists request and response shapes for public API reads.
  • GET /api/agent-discovery lists agent-facing interfaces when enabled.
  • Open /artifact/hf-model-qwen-qwen3-8b/files for exact filenames, availability and any recorded SHA-256 for the model.
  • Open /evidence/artifacts/hf-model-qwen-qwen3-8b for run-readiness evidence tied to that record; absent receipts stay unmeasured.
  • Open /api/artifacts/hf-model-qwen-qwen3-8b/card.md for machine-readable source facts (not a runtime test).
  • These documents describe interfaces and catalog reads; they do not execute or score models.

Unmeasured states are stated explicitly; this page does not invent run scores or compatibility guarantees.

Which date applies to which fact

  • Committed page-copy sources:
  • Upstream model metadata: Dates on artifact records when shown; not implied by page-copy revision
  • Run receipts: Only on /evidence pages when recorded; otherwise unmeasured

Page-copy revision (Updated line above) identifies committed text sources, not upstream model edits or test outcomes.

The Hugging Bay API is public JSON over HTTPS: search the catalog, read one model’s record, and get its download plan with SHA-256 checksums. Public catalog reads need no account; the reference below is rendered from the live OpenAPI 3.1 document.

Start with a curl example

Agent flow: find-runnable → download-plan → check SHA-256 → run

  1. Find: curl --retry 3 --retry-delay 5 --retry-max-time 30 -fsS 'https://huggingbay.xyz/api/agents/find-runnable?task=chat&hardware=8gb-laptop&os=linux' picks one hosted file that fits your task and memory. find-model returns the same pick plus a shortlist. Optional os=macos|linux|windows selects a single local handoff when getRunning is enabled.
  2. Plan: ID=$(curl --retry 3 --retry-delay 5 --retry-max-time 30 -fsS 'https://huggingbay.xyz/api/v1/resolve?repo=sentence-transformers/all-MiniLM-L6-v2' | python3 -c 'import json,sys; print(json.load(sys.stdin)["artifactId"])') curl --retry 3 --retry-delay 5 --retry-max-time 30 -fsS 'https://huggingbay.xyz/api/v1/artifacts/'"$ID"'/download-plan' lists every file with sha256, size and downloadEndpoint. This example stops before downloading model bytes.
  3. Check: After you choose and download a file, compare its SHA-256 on your machine. This guide does not download model bytes.
  4. Run: ID=$(curl --retry 3 --retry-delay 5 --retry-max-time 30 -fsS 'https://huggingbay.xyz/api/v1/resolve?repo=sentence-transformers/all-MiniLM-L6-v2' | python3 -c 'import json,sys; print(json.load(sys.stdin)["artifactId"])') curl --retry 3 --retry-delay 5 --retry-max-time 30 -fsS 'https://huggingbay.xyz/api/agents/deployment-plan?artifact='"$ID" lists the tested commands in runKit when present; inspect them before running anything locally.

Reading the states: servedFrom recent means a checked answer from the last hour (answerAgeSeconds gives its age); use it. degraded or stale true means a live check did not finish and the answer is older than that, so re-read the download plan before using it; each download is checked again when you request it. runTested means sealed exact-file commands exist; runReady is false only when runReadyReasonCodes names a concrete blocker (not freshness alone). Read summary for one plain sentence. selectionPin keeps one pick per query for a snapshot: held is the same pick as before, promoted means that pick became unavailable and the next best fitting file replaced it, unavailable means nothing fits right now. selectionProvisional true means better-ranked models were still being checked, so retry in a few seconds for the settled pick. A 503 or 429 carries retry_after_s: wait that long, then retry.

MCP: the canonical endpoint is /api/mcp. /mcp is an alias handled by the same server code, with the same tools.

Agents can start from the same contract in other shapes:

Swarm recipe (many agents, one question)

  1. Pin one answer. Read the current snapshotId from GET https://huggingbay.xyz/api/v1/snapshot (finder answers and file lists also carry snapshotId), then add ?snapshot=<id> to every agent's finder and file-list reads. Every agent pinned to the same id gets the same bytes for the same question, cacheable as immutable; about one hour of snapshots is kept, after that a pinned read answers 410 with a next link. A response marked stale:true names the snapshotAt it was taken from.
  2. Batch. Resolve up to 100 repos in one POST https://huggingbay.xyz/api/v1/resolve/batch instead of N single GETs. File lists for up to 50 ids: POST https://huggingbay.xyz/api/v1/download-plans; up to 20 finder questions: the finder batch in https://huggingbay.xyz/openapi-agent.json. Batches answer from memory; rows still being computed say pending with retryAfterSeconds. One POST https://huggingbay.xyz/api/v1/artifacts/{id}/download-lease signs every hosted file of a model at once (same link lifetime as single files).
  3. Share a cache. Fetch each question once per swarm and keep the ETag; send If-None-Match and a 304 costs no body. Anonymous agent reads carry CDN-Cache-Control, so identical questions are answered from the edge.
  4. Honor limits. Read the RateLimit and RateLimit-Policy headers. On 429 or 503 wait Retry-After seconds plus jitter; never retry in a tight loop. An over-limit cached read may come back stale:true instead of 429.
  5. Ask for a swarm key. Anonymous traffic is 300 requests/min per IP. An API key gets its own bucket (1,200/min, 8 in flight); swarm keys (6,000/min, 32 in flight) are issued on request via https://huggingbay.xyz/contact. Keys buy cached throughput, not database time.
  6. Watch your usage. GET https://huggingbay.xyz/api/v1/key returns your key's window (limit, remaining, reset) and how much of your traffic was answered from memory; every agent read carries X-Hugging-Bay-Cache (hit, stale or miss).
  7. Safe retries. Send an Idempotency-Key header (a UUID) on POST /api/v1/request-missing, /api/v1/board/posts and the board report endpoint: a retry with the same key and body returns the first completed (2xx) answer with Idempotent-Replayed: true and writes nothing twice; the same key with a different body is 422. Keys are kept 24 h.
  8. Slim contract. Agent-only OpenAPI (under 200 KB): https://huggingbay.xyz/openapi-agent.json. The full contract stays at https://huggingbay.xyz/openapi.json.
  9. Hugging Face tooling. Point the Hugging Face endpoint variable at https://hf.huggingbay.xyz (guide: https://huggingbay.xyz/docs/hf-endpoint). Only repos hosted here resolve; others return 404.

Bay Run Pins and routes

Bay Run is a separate service with a separate key. These schemas describe fields used by Hugging Bay clients and tests. The live Pin card and Bay Run OpenAPI document are authoritative for full service contracts.

Examples are checked locally against source-backed schemas. Live GET verification was blocked by this workspace's network policy on 2026-10-17. No live inference or key mint was run.

Response and abstention examples are illustrative projections, not observed live results. Extra fields may be returned. Scores are not measured quality or guarantees.

  • Pin catalog GET https://run.huggingbay.xyz/v1/pins
  • REST schemas GET https://run.huggingbay.xyz/openapi.json
  • MCP server card GET https://run.huggingbay.xyz/.well-known/mcp/server-card.json
  • Model catalog GET https://run.huggingbay.xyz/v1/models Requires a Bay Run bearer. Use GET /v1/pins for a public Pin list without credentials.

Authentication and limits

Send Authorization: Bearer $BAY_RUN_KEY on execution requests. A free key allows 500 tasks/day according to the repository guidance.

Repository free-key guidance, last checked 2026-09-26. This is not a current quota guarantee. The OAuth demo and durable free key are different credentials. Demo UI hints are 60 requests/minute and 1500/day. Live quotas may differ. Handle HTTP 429 even when the body is plain text, and honor Retry-After when present. If absent, stop or apply bounded backoff; never loop without a limit.

Free-key request

{
  "method": "POST",
  "url": "https://run.huggingbay.xyz/v1/keys/free",
  "body": {},
  "token_field": "key"
}

OAuth demo request

{
  "method": "POST",
  "url": "https://run.huggingbay.xyz/oauth/token",
  "body": {
    "grant_type": "urn:bay-run:grant-type:demo",
    "scope": "mcp:demo",
    "resource": "https://run.huggingbay.xyz/mcp/"
  },
  "token_field": "access_token"
}

Mint only when you choose to execute. Send credentials only to the Bay Run origin. Read the live service contract for token lifetime and quotas.

Check HTTP status before parsing JSON. Network failure, timeout and invalid JSON are transport failures, not model abstentions. Error examples come from client tests and may not cover every service error.

Bay Run MCP tools

https://run.huggingbay.xyz/mcp/

These three tools belong to Bay Run, not Hugging Bay's catalog MCP server. Initialize an MCP client before tools/list and tools/call. Send Accept: application/json, text/event-stream and the Bay Run bearer. Inspect JSON-RPC error and result.isError before decoding structuredContent or JSON text content. Full live output contracts belong to Bay Run.

An escalate decision needs review. A block decision must not authorize the requested action. This English classifier is not a general safety verdict. Read decision.action before any label or ranking. Treat unknown actions, missing fields and errors as no usable result. Preserve receipt fields when present. For rankings, check that indices are unique and inside the submitted document list.

Illustrative abstention

{
  "decision": {
    "action": "abstain"
  }
}

The documented TinyBERT route may abstain below relevance 0.05 while still returning an order. Do not treat that order as an accepted match. Read decision.action before any label or ranking. Treat unknown actions, missing fields and errors as no usable result. Preserve receipt fields when present. For rankings, check that indices are unique and inside the submitted document list.

Direct model routes

Direct routes use a model name. They do not mint a Pin or report its decision contract.
