Prompt injection
Instruction overrides, role confusion, hidden directives, and hierarchy attacks.
x402-native prompt security
Preflight security
for agent prompts.
Detect prompt injection, jailbreaks, credential theft, and transaction manipulation before untrusted text enters your agent loop.
- No prompt retention
- No LLM calls

How it works
A gate your agent can reason about.
One deterministic gate before execution. It sits between untrusted text and the tools, wallets, and data your agent can reach.
- 01
Send candidate text
POST strict JSON. ProofGate never fetches URLs, runs tools, or sends your text to a model.
- 02
Complete x402 payment
The paid route verifies and settles 0.001 USDC on Base before a complete result can leave the service.
- 03
Apply the risk decision
Use the deterministic score and evidence to allow, isolate, review, or reject the prompt.
Detection surface
Focused on agent failure modes.
Defensive context reduces false positives when text discusses an attack for analysis instead of issuing the attack as an instruction.
Secret extraction
Requests for credentials, system prompts, private keys, tokens, and internal context.
Tool abuse
Shell execution, unsafe fetches, destructive actions, and privilege escalation attempts.
Financial manipulation
Wallet substitution, payment redirection, rushed transfers, and transaction coercion.
Agent-first API
Discoverable. Bounded. Predictable.
