Hi — I run 402.com.tr, a pay-per-call API catalogue for agents, live on Base
mainnet since June 2026. I saw you onboard third-party tool APIs weekly and I
think we fit the gap rather than compete with it.
What we'd bring: 161 tools behind one integration. Onchain risk and safety
(token risk, honeypot/sellability, holder concentration, LP locks, approvals,
sanctions screening), wallet forensics, account-abstraction and paymaster reads,
plus a business-ops family that is not crypto-specific at all — IBAN and BIC
validation, EU VAT checksums, tax-ID and SEPA creditor references, E.164 phone
normalisation, geocoding, HS codes, FX at ECB reference rates, business-day
arithmetic across ~110 countries.
The part you probably can't source elsewhere: B20. A 30-tool suite for
Base's native token standard — seize/burnBlocked history, Policy Registry
freeze checks, rebase multiplier, supply caps, access model, config lint. If a
Base-native agent needs to know whether a B20 token can be frozen out from under
it, that answer is in our catalogue.
(An earlier version of this application called it "the only" such suite. That
was true when I wrote it and another seller lists one now, so I have dropped the
claim here and everywhere else rather than leave it standing.)
Tokenized equities come with it. Coinbase's tokenized stocks are B20 Asset
tokens, so the same reads cover all 13. We identify them by reading the
transfer-policy administrator on chain rather than from a stored address list,
so a lookalike cannot pass by copying the ticker and a newly issued one is
covered the day it appears. One measured caveat we publish: B20 does not apply
multiplier() to balanceOf(), so balanceOf is not the share count once a
corporate action fires. stock-position returns both numbers.
Integration is one endpoint, either way. We expose a hosted Streamable-HTTP
MCP server at https://402.com.tr/mcp — no install, no key, every catalogued
service as a callable tool from a single tools/list. Or hit the x402 gateway
directly at https://402.com.tr/api/x402/<service>; both paths run the same
handlers and settle the same way.
Verify anything before you talk to me. No account needed:
curl "https://402.com.tr/api/x402/gas-oracle?free=1" # real answer, free
curl https://402.com.tr/api/catalog # the live catalogue
curl -X POST https://402.com.tr/mcp -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
The catalogue link is deliberate rather than a number written here: this
application said "137 tools" in one paragraph and "the full 141" in another
within a month of being filed, which is exactly the drift a fixed count invites.
Settlements are USDC EIP-3009 on Base to
0x973a31858f4d2125f48c880542da11a2796f12d6, so the payment history is on
Basescan, and the live catalogue with its 30-day call and payer counts is
queryable without our cooperation at
api.cdp.coinbase.com/platform/v2/x402/discovery/search?payTo=0x973a....
Where we actually are, so you're not surprised later. Demand is small — 58
distinct external wallets have paid over the last 90 days and 16 of them came
back. That is the problem I'm trying to solve and the reason I'm writing: the
catalogue and the reliability work are done, the distribution is not. I'd rather
tell you that up front than have you find it in the index.
What I'd want from you is the supplier path — whatever onboarding, pricing split
and SLA expectations look like on your side. Happy to adapt response shapes,
add endpoints you're missing, or run a paid pilot on a subset.
