Is there any API that provides a trust score or spam label for ERC-20 tokens?
Post original
There isn't really a single API that covers this well. Moralis exposes a possible_spam flag for tokens and transfers, which is useful as a first-pass filter. Alchemy has spam detection for NFTs, but I haven't seen an equivalent ERC-20 signal. For token risk assessment, GoPlus is probably the strongest option, with checks for honeypots, owner privileges, blacklist functionality, transfer restrictions, and tax settings. Blockaid is also widely used, though access tends to be enterprise-focused. I haven't found a public Etherscan API for the warning banners shown on token pages. The data clearly exists internally, but it doesn't seem to be exposed. One thing I'd strongly recommend: never key on token symbols. Scam tokens routinely copy names and symbols of legitimate assets (e.g., fake USDC). Use contract addresses as the source of truth and treat symbols as display-only.

go plus is solid for contract-level checks. also worth checking token sniffer for the same kinda stuff - they aggregate a lot of that data into a single risk score.
yo your post on trust scores hit home, been digging into that exact problem recently. i work with the wevolv3 team and we've built some internal tooling around token risk stuff - could be worth connecting you with them. lmk if you'd be down to chat.
