Stack what you need.

Pay for the extras when they apply. Most publishers never need them.

Live-traffic attestation
+$299/mo per service
Attest a sampled 1% of production requests, not just offline evals. Proofs that your shipping product matches the listed score.
Custom benchmark
$2,999 setup + $499/mo
We pin your own eval as a first-class Benchlist suite. Dataset hosted on IPFS, methodology open-sourced, runs attestable by all 6 attestors.
Quorum mode
+50% per run
3-of-5 attestors must agree independently before the score publishes. Higher trust for regulatory-grade claims.
TEE attestation
+$999/run
Confidential eval for publishers who can't share transcripts (PII, regulated data). Intel TDX + AWS Nitro enclaves, attestation digest on-chain.
Data feed · Institutional
$999 – $9,999/mo
Real-time SSE stream of every new verified run. Historical time-series CSVs. Used by AI-procurement teams at F500s and by investment analysts covering the AI stack.
Certification renewal
$999/yr per service
Annual "Benchlist Certified" status with automatic re-runs of canonical suites. Badge auto-updates; lapsed certifications are flagged.
Run an attestor · earn fees

Attestors earn ~70% of each Verified run they process, post 1–5 ETH stake, and get slashed for proven misconduct. If you have spare GPU and want inbound revenue rather than outbound cost, read the operator guide →

Where your money goes.

We’re transparent about cost structure because our whole value prop is honesty. A test is a cryptographic proof queued for Ethereum mainnet anchor, not a cached score. Tap the row to see the full breakdown.

What you actually pay for: a fresh, replayable run with a signed receipt — not a vendor blog claim. collapse

Signed-attestation tier (live now, $5 / test). A managed run executes against the canonical sample set, every transcript is captured, a Merkle commitment is built, and the result is signed with our Ed25519 attestor key. The signature is replayable in a browser at /verify/<run_id>. Cost structure is honest: the inference itself is cheap. Most of what you pay covers the certification, indexing, archival, and the open-source pipeline that makes the receipt trustable.

Aligned Layer ZK tier ($15 / test). Adds an SP1 or Risc0 ZK proof of the scoring function and an Ethereum L1 anchor. Real cost: ~$0.50–$2 in batcher fees + L1 gas + ~$0.50–$2 in proof generation. Currently requested status, proofs are queued at bl:queue:aligned and lit up when our operator drains. We don't charge ZK pricing for runs that haven't anchored yet.

Heavy benchmark suites (SWE-bench Verified, τ-Bench, WebArena) cost $25+ per run because the agent harness burns more tokens. Quoted at the door, no surprise bills.

Billing questions.

Where does each test's cost go?
For signed-only: ~$0.05-0.30 LLM inference, ~$0.005 platform infra, the rest funds the open-source runner + dataset curation + indexing. For Aligned ZK upgrades: add ~$1-4 for proof generation + L1 gas. See the honest breakdown above. We don't bill the ZK tier until the proof actually anchors.
Do you accept crypto?
Yes, native ETH on Base (recommended, cents of gas), Ethereum L1, or Arbitrum. Click “Pay with ETH” on any tier: we give you a receiving address + the live ETH amount (rate refreshed on open), you send, paste the tx hash, and /api/v1/crypto verifies the transfer on-chain before granting credits. Card checkout via Stripe also fine. We do not accept ERC-20 tokens.
What if my run fails verification?
Full refund if the failure is on our side (runner bug, attestor outage). No refund if your service returned errors or malformed responses during the run.
Do you take a cut of listings?
No. We are not a commerce marketplace. We don't take a revenue share of your service. We charge for verification compute + gas.
