A credit score
for AI services.
Every MCP server and API endpoint gets scored by NVIDIA Nemotron 3 Ultra before money moves. Good endpoints clear the bar and touch Stripe. Bad ones don't — and that's verifiable, not just a UI promise.

The rails are done.
Trust isn't.
Identity tells you who an agent is. Payments tell you how money moves. Neither tells you whetherthe service is any good — or won't rip you off.
Identity
AP2 / FIDO
Cryptographic agent identities. Every autonomous agent can prove who it is with non-spoofable credentials.
Payments
x402 / Stripe
Programmable money movement. Agents can pay APIs autonomously over HTTP, with on-chain settlement and receipts.
Reputation
Beacon
Is the endpoint actually good? Beacon scores every MCP server and API with NVIDIA Nemotron 3 Ultra, then enforces that score with a Stripe escrow gate. Bad actors never reach Stripe at all.
- Shadow MCP servers
- Prompt-injection payment attacks
- Unvetted, anonymous endpoints
Score, hold, attest —
in that order.
Probe
When an agent wants to pay a new API, Beacon hits the endpoint live. NVIDIA Nemotron 3 Ultra — served via Nous Research's inference API — judges the response for accuracy, error rate, and hallucination. That feeds directly into a 0–100 trust score. If the live call fails, a deterministic mock evaluator falls back, but the evaluator field always tells you which brain scored it.
Escrow
Endpoints scoring ≥ 70 pass through to a real Stripe PaymentIntent with capture_method: manual — funds held until the agent calls execute. Endpoints scoring below 70 are blocked: zero Stripe API calls, zero PaymentIntents, zero risk. The safety gate is auditable directly in the Stripe dashboard.
Attest
Verifier nodes restake ETH to sign scores via an EigenLayer AVS. Collusion or false reporting triggers slashing of the staked collateral. This is not a trust-us promise — it's a verify-or-punish guarantee. Every score ships with a cryptographic proof your agent can independently verify.
Query before you pay
POST /v1/probe to score the endpoint, then POST /v1/escrow/validate to hold or block funds. PASS decisions create a Stripe PaymentIntent. FAIL decisions terminate cleanly — no Stripe calls, no exposure. Both halves are independently verifiable by any observer.
Real scoring. Real escrow.
Both verifiable.
Nemotron-scored trust API
Every probe is judged by NVIDIA Nemotron 3 Ultra via Nous Research's inference API. The evaluator field on every response tells you whether a live model or a deterministic fallback scored it — no hidden black box.
Live endpoint probing
Beacon hits endpoints live, not from cached data. Nemotron evaluates the actual response for accuracy, hallucination, and error rate. Endpoints can't game scores by serving only real users well.
Uptime & latency SLAs
Real-time uptime percentage and p99 latency tracked across every probe. Know before you pay whether an endpoint is reliably fast or quietly degraded.
Dispute & scam-flag history
Every unresolved dispute, refund request, and scam report is indexed and surfaced. A permanent, auditable record that bad actors cannot erase or reset.
Stripe escrow enforcement
Trust score ≥ 70 creates a real Stripe PaymentIntent with manual capture — held until the agent executes. Below 70 the gate blocks entirely: zero Stripe calls, zero risk. Verifiable in the Stripe test dashboard.
EigenLayer AVS attestation
Verifier nodes restake ETH and face slashing for dishonest attestations. Every score ships with a cryptographic proof — your agent can verify independently, not just trust Beacon's word.
Not a UI promise.
A verify-or-punish guarantee.
Nemotron scores are economically enforced by EigenLayer verifiers who stake ETH and face slashing for dishonest attestations. The escrow gate is Stripe itself — not a message saying "blocked." Both halves are independently auditable by any observer.
Flywheel
Evaluated by Nemotron, not heuristics
NVIDIA Nemotron 3 Ultra judges every live probe for accuracy, hallucination, and error rate via Nous Research's inference API. The evaluator field on every score tells you exactly which brain ran the assessment.
Enforced by Stripe, not a message
A trust score below 70 doesn't show a warning — it terminates the flow before any Stripe API call is made. PASS decisions create real PaymentIntents with manual capture. The enforcement is Stripe itself.
Guaranteed by slashing, not promises
EigenLayer verifier nodes stake real ETH to attest scores. Collusion or false data triggers on-chain slashing. This is an economic guarantee backed by skin in the game, not a terms-of-service clause.
Auditable by anyone, not just Beacon
Every score includes a cryptographic attestation proof. The Stripe test dashboard independently shows PaymentIntents only for PASS decisions. Any observer can verify both halves without trusting Beacon.
Why Beacon, not
the alternatives.
Existing tools benchmark models or rank within a single marketplace. Beacon is the only neutral, verifiable, live-endpoint reputation layer that travels across the entire agent economy.
