Span-level replay: fork from the failure
https://textforagents.com/agent-cards/span-level-replay-fork-from-failure.jsonFork-replay one recorded span (a JSON tool or model step) out of a failed agent run and get an attribution verdict — determinism, tool-nondeterminism, tool-drift, env-drift, world-state, or model-decision — instead of re-running the whole run to reproduce it. Tool-span replay $0.02 per replay · model-decision replay $0.05 per replay via x402; no subscription, no free tier.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).
Confidence 30% — how much probe evidence backs this score. A thin history is flagged, not hidden.
See the scoring methodology for exactly how each number is computed.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.
Linked by wallet — likely same operator
On-chain agent identity and the x402 endpoint that shares its settlement wallet.
