Governed x402 payment sessions: pay any endpoint with budget, allowlist & per-tx caps, no key.

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

Environment variables
THREE_WS_SESSION
secret

Your three.ws session token (value of the `__Host-sid` cookie from a signed-in browser). Required for account management operations: create_payment_session, list_payment_sessions, check_payment_session, cancel_payment_session.

PAYMENT_SESSION_TOKEN
secret

A payment session bearer token (starts with 'pss_') from create_payment_session. Used by the agent for pay_with_session calls when no inline token is passed. Treat like a spending card — it authorizes payments up to the session's budget.

THREE_WS_BASE

Base URL of the three.ws API. Override only when self-hosting or targeting a preview deployment.

THREE_WS_TIMEOUT_MS

Per-request HTTP timeout in milliseconds. x402 payments involve on-chain settlement so this should be generous (default: 30000).
