agent-claim-output-verifier
Agent Claim Output Verifier
Map an autonomous agent claim or output to supplied evidence and return SUPPORTED, PARTIALLY_SUPPORTED, NOT_PROVEN, or CONTRADICTED with explicit unsupported elements, contradictions, missing evidence, and recommended verification. Price: $0.50 via x402. Generate one _salt19_operation_id per intended purchase, preserve it across retries, and add _x402_payment_signature after satisfying the challenge. A stable _salt19_operation_id is required and makes semantic retries at-most-once.

agent-code-change-risk-gate
Agent Code Change Risk Gate
Static pre-merge risk gate for autonomous code changes: inspect a supplied unified diff for security-sensitive surfaces, destructive operations, architecture/constraint conflicts, test requirements, rollback risk, and bounded breaking-change risk before an agent merges or deploys.

url-http-preflight
Url Http Preflight
Inspect a URL before an autonomous agent calls it, and preflight or verify a website or external API endpoint is healthy and safe to call by checking HTTP status, redirects, latency, and security headers. Price: $0.03 via x402. Generate one _salt19_operation_id per intended purchase, preserve it across retries, and add _x402_payment_signature after satisfying the challenge. A stable _salt19_operation_id is required and makes semantic retries at-most-once. _salt19_operation_id is recommended but optional for standard x402 compatibility. Security boundary: public HTTP(S) only. Credentialed URLs, localhost, .local/.internal hosts, loopback, RFC1918/private, link-local and cloud-metadata targets are rejected; every redirect target is revalidated; fetches are time-bounded and response-size bounded.
