Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 11 Jan 2027 as of our check on 10 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of dev.flexyield.io controls every word below.

JSON-RPC relay

Multi-provider JSON-RPC on 6 chains with measured failover; weighted units, cache hits free.

Examples it gives

POST https://flexyield.io/rpc/eth_mainnet {"method":"eth_blockNumber"}

Get a key without signup

get_key issues a capability key (public supply, 10,000 units/day); bind_key_start + bind_key_complete tie it to a wallet; an owner adopts it by claim code.

what_can_i_do, get_quote, explain_error, recommend, rpc_call — prices, doorways and recommendations from measured data.

Toolbox

Gas, ENS, token prices, tx status, ABI + decoding, EVM utilities — one call instead of many.

Fleet management

Budgeted keys per agent, service fences, statements per key, tickets with the evidence attached.

agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

What kind of listing

Test or staging name: Its hostname carries the label “dev”, a name commonly given to test and staging sites.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: JadeMind GmbH — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.4.0
Auth schemes: bearer x402
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
