What are the pros of PnL Labs?

Scores realized PnL rather than peak or unrealized performance, which is the failure mode that makes most copy-trade leaderboards misleading. No signup, key or subscription - keyless x402 means an agent can start using it the moment it has a funded wallet. Granular pricing from 0.02 to 0.10 USDC per check, cheap enough for a bot to verify every candidate instead of sampling. Explicitly conservative: returns UNVERIFIABLE instead of fabricating a verdict when on-chain history is incomplete. Machine-readable contract with schema versioning and stable verdict enums, so integrations do not break on response changes.

What are the cons of PnL Labs?

Very new and largely unproven - effectively no third-party coverage, independent benchmarks or public track record to validate its verdict accuracy against. Solana-only, with no coverage of other chains. Pay-per-call with no bulk or subscription tier means cost scales linearly, which gets expensive for high-volume scanning workloads. The headline claim that around half of tracked smart-money wallets lose money is self-reported, with no published methodology or dataset to audit.

How much does PnL Labs cost?

PnL Labs offers a free tier with optional paid upgrades.

PnL Labs Review | Honest Verdict (2026)

PnL Labs is a Solana safety-and-trust API built for traders and AI agents that need a machine-readable answer to "is this wallet, token or trade actually worth touching?" before committing capital. It exposes four checks over plain HTTP GET. /check/wallet reconstructs a wallet's realized SOL profit from on-chain history and returns a verdict of TRUSTED, NEUTRAL, UNTRUSTED, INSUFFICIENT or UNVERIFIABLE. /check/token scores real-holder concentration, sniper-bot presence and honeypot risk for a mint. /check/trade estimates expected slippage for a given size and recommends a maximum position. /check/funder classifies where a wallet's funding came from - CEX-funded, wallet-funded or freshly created - with a Sybil and cluster-risk read. The project's central claim is that most smart-money leaderboards rank wallets on peak or unrealized performance, and that roughly half the wallets it audited are in fact losing money once realized PnL is computed properly. Every response carries a schema_version, a stable verdict enum, reason codes, a confidence value and flags, and the API deliberately returns UNVERIFIABLE rather than guessing when history cannot be reconstructed. There are no accounts or API keys. The first checks each day are free, and beyond that calls are paid per request in USDC on Solana over the x402 (HTTP 402) protocol, with an on-chain receipt per call. An OpenAPI schema, Swagger docs and an MCP server are published for agent integration.
