What do they say they sell?

Descriptions and categories below are claims from the seller's own listings, organized by the published category rule — never verified by us. Find by claim, trust by evidence: the evidence is the table above.

Address checksum and validation verification-conformance auto-assigned

Validates an EVM address and returns it in EIP-55 mixed-case checksum form. Catches typos before you send funds: an address that fails the checksum is almost always mistyped. — seller-asserted
flat-rate-llm.kikoribera03.workers.dev/v1/crypto/sanctions data-access auto-assigned

Checks one crypto address against the OFAC SDN list published by the US Treasury, across 16 currencies including Ethereum, Bitcoin, Tron and USDT. A hit returns the actual list entry - sanctioned entity, its type and its sanctions programmes - not a risk score. Exact matching only, never fuzzy. Ever… — seller-asserted
EIP-1559 fee suggestion data-access auto-assigned

Suggested maxFeePerGas and maxPriorityFeePerGas from the last 20 blocks of real fee history, at slow, normal and fast percentiles. Beats guessing a gas price and getting stuck in the mempool. Via eth_feeHistory. — seller-asserted
ENS name resolution other auto-assigned

Resolves an ENS name to its address, or an address back to its primary ENS name, reading Ethereum mainnet directly. Names are what humans paste and addresses are what chains need. — seller-asserted
Coin flip other auto-assigned

Flip one or more fair coins and get heads or tails, with the tally. Cryptographically random, not Math.random. For tie-breaks and A/B splits an agent has to decide on its own. — seller-asserted
Estimate gas data-access auto-assigned

Estimates the gas a transaction would need and prices it at the current gas price, before you sign anything. Also the cheapest way to find out that a call would revert. Via eth_estimateGas. — seller-asserted
Email address check communications auto-assigned

Scores one email address 0-100 with a verdict (ok, risky, disposable, undeliverable, invalid) and the evidence under it: every point lost is itemised with the field that proves it. 12,141 disposable domains from two maintained open lists pinned to a commit, 4,897 free providers, 1,018 role names, ty… — seller-asserted
Password generator inference auto-assigned

Generate strong random secrets from the platform CSPRNG, with the entropy in bits so you can judge them. Four alphabets, including one with no look-alike characters for anything a human has to read back. — seller-asserted

USDC transfers on Base to 0xc210…e9ff, blocks 51047974–52515816, excluding flagged exchange/fan-out senders and self-transfers (exclusion list flags-2026-10-13). Computed 2026-10-13 under score-v1.0.0. Methodology
