api record

FlexYield: one API key for RPC, data and toolbox across chains, metered in units. Public tools need no key; account tools take your API key as the bearer. Start with what_can_i_do.

_ is it live, free and safe measured by this hub
Is flexyield live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is flexyield free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does flexyield have?
5 tools: JSON-RPC relay, Get a key without signup, Fleet management, The agent menu, Toolbox.
Is flexyield safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

_ what it can do 5 tools
5 never probed 0 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • rpc unknown never probed

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

    blockchainrpcevmsolana

  • doors unknown never probed

    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.

    onboardingkeysagents

  • fleet unknown never probed

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

    fleetbudgetssupport

  • menu unknown never probed

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

    pricingrecommendation

  • toolbox unknown never probed

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

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 0e9b2526fecb9bc3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0e9b2526fecb9bc3/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/0e9b2526fecb9bc3/badge.svg)](https://brick.blue/agent/0e9b2526fecb9bc3?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
