Pitch in 60 seconds Benchlist is the open registry for verified AI benchmark scores. Every score is: - Run on a canonical HuggingFace sample set (deterministic seeded sampling). - Signed by an Ed25519 attestor at submission time. - Hosted at a permanent /verify/ URL with the full transcript Merkle commitment. - Replayable for $0.50 by any third party who wants to challenge. - Optionally anchored on Ethereum L1 via Aligned Layer (queued today, not yet on mainnet). Why a model lab or inference provider would care: a benchmark number you cite in your release blog is "self-reported" until a third party signs it. Customers discount self-reported numbers. A Benchlist receipt is the receipt. # 2. Anonymous probe (no auth, free, rate-limited) The simplest call. No API key. n capped at 3. Rate limit: 1 successful probe per IP per hour, 5 per day. POST https://benchlist.ai/api/v1/probe Content-Type: application/json { "benchmark": "gsm8k", "model": "anthropic/claude-haiku-4-5", "n": 3 } Response (200): { "run_id": "run-probe-abc123", "verify_url": "https://benchlist.ai/verify/run-probe-abc123", "score": 100.0, "score_ci": { "lower": 38.4, "upper": 100.0, "half": 30.8 }, "n": 3, "benchmark": "GSM8K", "model": "anthropic/claude-haiku-4-5", "attestor": "benchlist-probe", "signature": "a1b2c3d4...…", "pubkey": "attestor-id:…", "duration_ms": 18402, "upgrade": "For n=50 attested runs, get a free key at /api/v1/submit and call /api/v1/run." } Error responses: - 400 unknown benchmark → use one of the supported ids (see /api/benchmarks.json). - 429 rate limit → response includes retry_after_seconds + upgrade hint. - 503 if our inference pool is misconfigured → fall back to /api/v1/run with a paid key. Browser-friendly version: https://benchlist.ai/try (form + result panel). # 3. Email signup + key issuance POST https://benchlist.ai/api/v1/submit Content-Type: application/json {"kind": "signup", "contact": "you@company.com"} Response: `{ ok: true, key_delivered_to: "you@company.com" }`. Email arrives within 60 seconds with a `bl_live_eyJ...` key. Key format is `bl_live_.`. Carry as `Authorization: Bearer bl_live_...`. Other `kind` values (same endpoint): - `list` — list a service (model, benchmark, etc.) for inclusion - `run` — publish a pre-signed run.json (for users who self-attest with our runner) - `waitlist` — join a future product waitlist - `dispute` — file a dispute on a published run - `contact` — generic contact form - `attestor` — register your own attestor pubkey - `newsletter` — Contamination Index subscribe # 4. Paid run lifecycle POST https://benchlist.ai/api/v1/run Authorization: Bearer bl_live_... Content-Type: application/json { "service": "anthropic-claude", "model": "claude-sonnet-4-5-20250929", "benchmark": "humaneval", "n": 50, "provider_key": "sk-ant-…" // OR keep at /v1/admin/provider_keys for re-use } Response: 202 Accepted with run_id, est_seconds, charge breakdown, and verify_url. The run materialises in ~10-15 min for n=50; status is at `/api/v1/status/`. Inference cost goes through your provider key, not ours. Charge breakdown: - $5 standard verification fee (single benchmark, n=50) - $10 long-context (>32k tokens) - $25 agent / Docker harness - $0 if you've pre-loaded credits via /api/v1/checkout # 5.

OR body: {"email":"…"} Returns Stripe Customer Portal URL. Buyer can update card, cancel sub, download invoices. # 7. Trust levels The site shows four pill colours for run cards: - **`Verified ⛓` (green/blue)** — Full ZK proof of the scoring function settled on Ethereum L1 via Aligned Layer. **Optional / opt-in.** Today: queued, not yet anchored. Don't claim a run is on-chain unless `verification.alignedBatchId` is set. - **`Attested` (green)** — Ed25519 signed by the Benchlist attestor. Replayable. Trust floor. - **`Local` (teal)** — Run on the publisher's own hardware (Ollama/vLLM) using the canonical sample set. Signed. - **`Self-reported` (grey)** — Vendor-disclosed. NOT cryptographically verified. Surfaced for completeness, never as the leaderboard winner unless trust filter is loosened. Sort order on /best and /leaderboard: trust tier first, then Wilson lower bound second. # 8. Replay primitive Every run.json includes a `replay.command` field with the exact command to reproduce. Anyone can pay $0.50 to have a fresh attestor (a different one) re-execute and post a second signed receipt. Two signed receipts, different attestors → compounding evidence. Mismatched receipts → public dispute. The `/replay` UI is currently in private beta; the underlying primitive is the canonical `replay.command` in every run. # 9. Disputes If a published run looks materially wrong: 1. Reproduce locally using the `replay.command`. 2. Post 0.1 ETH bond. **Bond contract is on testnet today** — disputes are adjudicated by 3 random attestors via human review while the on-chain contract is being landed alongside our second attestor. 3. 2/3 supermajority decides; upheld → bond returned + 0.02 ETH bounty, denied → bond forfeited.

What we explicitly do NOT do - We do not run un-disclosed harness modifications. Every run uses the canonical sample + canonical chat template; anything custom is flagged. - We do not hide failed runs. Every run.json has a `verification.status`; failed runs are public. - We do not proxy inference. You bring your provider key. - We do not gate the registry. Every run is public, CORS-open, edge-cached. - We do not claim a run is on Ethereum L1 unless `verification.alignedBatchId` is set. - We do not accept bribes for ranking. # 16.
