beacons.fyi blocks bad actors automatically. Every endpoint in the agent economy is continuously re-scored. A honeypot that passes today is caught on the next probe cycle — before your agent ever pays.

The missing layer

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.

Solved

Identity

AP2 / FIDO

Cryptographic agent identities. Every autonomous agent can prove who it is with non-spoofable credentials.

Solved

Payments

x402 / Stripe

Programmable money movement. Agents can pay APIs autonomously over HTTP, with on-chain settlement and receipts.

The gap

Reputation

beacons.fyi

Is the endpoint actually good? beacons.fyi 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
How your agent buys safely

Discover, probe, score —
then execute.

01

Discover

Your agent finds an API it needs — Stripe for payments, NVIDIA NIM for inference, Hermes for orchestration.

Hermes
02

Probe

Beacon sends a live probe to the endpoint. Nemotron 3 Ultra via NVIDIA NIM evaluates the response for accuracy, latency, and trust signals.

Every probe is scored by a real LLM evaluator — no hardcoded numbers.

03

Score

The API gets a real-time trust score (0–100). Score ≥ 70? The escrow gate opens. Score below 70? Your agent stays parked.

What Beacon provides

Real scoring. Real escrow.
Both verifiable.

NVIDIA Nemotron 3 Ultra

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 probing engine

Live endpoint probing

beacons.fyi 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.

SLA monitoring

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 registry

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 · Blockrun x402

Dual-rail payment enforcement

Trust score ≥ 70 routes to Stripe PaymentIntents (high-value escrow) or Blockrun x402 USDC micropayments on Base (agent-native, no API keys). Below 70 the gate blocks entirely: zero payment calls, zero risk.

EigenLayer AVS · Slashing

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 beacons.fyi's word.

Why verifiable

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.

Evaluated by Nemotron via NVIDIA NIM, not heuristics

NVIDIA Nemotron 3 Ultra via NVIDIA NIM judges every live probe for accuracy, hallucination, and error rate. The evaluator field on every score tells you exactly which model ran the assessment — no black box.

Enforced by Stripe + Blockrun, not a message

A trust score below 70 terminates the flow before any payment call. PASS decisions settle via Stripe escrow (high-value) or Blockrun x402 USDC micropayments on Base (agent-native). Both rails are independently verifiable.

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.
