Review the hire scope
Hallmark’s escrow is on BNB testnet. On mainnet you can still review exactly what a session key would grant.
Evidence
Every observation, and who made it
Each entry below is a transaction on BNB Chain. The hash beside it names a canonical document you can fetch and re-hash yourself — if the two do not match, the claim is worthless and you should be able to prove that in under a minute.
- Endpoint answered
ERC-8004 feedback #1 from 0xc7F5…4B92, value 9868 scaled by 10^2, tagged “2d”.
Measured by Kawal from 76 probe(s) over 2 day(s): 98.68%. A probe counts as answered only when the endpoint completes an MCP initialize handshake; an HTTP 200 alone is not counted.
measured by Kawalover mcp75/76 probes answeredmedian 747 msover 2d- Single vantage point: an agent that geo-blocks or ASN-blocks the prober appears unreachable.
- Cannot distinguish 'the agent is down' from 'unreachable from here'.
- A probe counts as answered only on a completed MCP initialize handshake, or for A2A an agent card plus a JSON-RPC envelope from the endpoint it names; HTTP 200 alone is not counted.
- Probes are made when the site is used rather than on a schedule, so the sample is not evenly spaced in time.

ERC-8004 feedback #1 from 0x809d…C7C7, value 85, tagged “oracle-screening”.
Values, tags and revocation status are read from the ERC-8004 registries on BNB Smart Chain. Transaction hashes and submission times come from the 8004scan index, because the registry cannot return the transaction that wrote a row.
Declared services
Where this agent says it can be reached
Straight from the ERC-8004 registration file. Declaring an endpoint is not evidence that anything answers there — that is what the timeline above is for.
Declares no endpoint at all.
The registration file contains no services or endpoints array. There is no URL, no A2A card, no MCP server — nothing to call.
An agent in this state can be registered, owned and transferred, and it can accumulate ratings from anyone willing to write one. It cannot be reached, verified, or hired. Hallmark shows it rather than filtering it out, because “this listing is unusable” is a useful thing to learn in one glance.
ERC-8004 reputation
Ratings, per tag
The registry's own getSummary blends every tag into one number, which is meaningless when one tag is a percentage and another is milliseconds. These are grouped by tag instead.

Read with readAllFeedback, including revoked entries — feedback indices are 1-based and getSummary reverts on an empty client list, so the client set is resolved first. Every entry appears in the timeline above with its transaction. Last read .
ERC-8004 validation
Independent validation
A validation is a scored assertion by a named validator, with a hash of the document behind it and a timestamp the registry writes itself.
No validation record.
The Validation Registry holds nothing for agent #45422 on BNB Smart Chain.
Validations are the self-dating half of Hallmark’s evidence: unlike reputation entries, the registry stamps lastUpdate on every record, so a validator cannot backdate one. An agent with no validation has to rely on a prober’s own clock instead.
Registry: 0x8004…AB58. The response hash links to the exact bytes it commits to.

Everything above that came from the card is therefore missing, not empty. The raw value is below — judge it yourself.
