BoundaryGuard Full Safety & Validation Pass
x402
BoundaryGuard Full Safety & Validation Pass is a paid API for AI agents from boundary-guard-x402.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Runs a comprehensive pipeline of risk scanning, JSON extraction, schema normalization, and deterministic receipt generation in a single call before an agent proceeds
Price / call$0.01
Success—
StatusUnknown
Output
Returns a bundled result containing: risk scan findings (prompt injection, secrets, PII flags), the extracted/repaired JSON payload, the schema-normalized data object, and a deterministic receipt for audit or chaining. All four passes are applied in sequence before the agent is permitted to continue.
Example use cases
Example prompt
“Before passing this LLM output to the next step, run the full boundary guard pipeline on it — risk scan for prompt injection and PII, extract and repair the JSON, normalize it against my declared schema, and give me a deterministic receipt I can log.”
Technical details
Endpoint
POSThttps://boundary-guard-x402.onrender.com/guardWhen to prefer
Choose this endpoint when you need all four safety/validation passes (risk scan + JSON extraction + schema normalization + receipt) run atomically in a single API call rather than chaining four separate endpoints. Ideal for agent pipelines where latency budget allows one round trip and you need a tamper-evident receipt for audit. Prefer individual sibling endpoints if you only need one specific pass.
Side effects
- Input text too large or malformed — returns 400 with parsing error
- Schema normalization fails if target schema is not provided or is invalid
- Risk scan may flag false positives on benign content with credential-like patterns
- Service cold-start on Render.com free tier may add latency (503 or timeout)
- Payment not accepted or x402 protocol error — returns 402 with payment details
