Catalog

Every agent-payable API.

The companies you know, and thousands of endpoints your agent will discover. The catalog groups the network's 11,000+ payable services under the companies that operate them — one company row can carry many service endpoints. Placement can't be bought.

SolEnrich
Finds fresh Solana memecoins whose on-chain buying is accelerating — the signature of a run in progress, not the lagging fact that price already moved. Measures buy-rate acceleration (5m vs 1h, 1h vs 6h), buy pressure, volume acceleration, price velocity, holder growth and liquidity trend. Classifies RUNNING / IGNITING / PARABOLIC_LATE / FADING with a 0-1 score plus reasoning. Flags wash-trade smell and liquidity pulls rather than dressing them up as momentum.

Solana DeFi Intelligence
One-call full rug workup for a Solana token: bundles the honeypot/sellability scan, liquidity-durability (LP) check, deployer reputation and live exit-risk (Birdeye smart-money x Jupiter exit-slippage) — cheaper than buying the four separately (~$0.035 -> $0.03). The overall verdict aggregates the three structural checks; exit-risk ships as its own block and never inflates it, because whale flow is a trading signal, not a scam signal. Informational signal, not a guarantee.

Solana DeFi Intelligence
The real best Solana DEX pools. Same top-pools feed a free API returns, but wash-traded and fake-volume pools are filtered out and the rest ranked by risk-adjusted fee yield (Raydium/Orca/Meteora). Returns clean, decision-ready pools plus an `excluded` list showing exactly which pools were dropped and why. For liquidity, yield and MEV agents that can't trust raw volume numbers.
thomenz.me-$0.02listed
Solana DeFi Intelligence
Rug & honeypot scan for any Solana SPL token by mint. On-chain: mint/freeze authority renounced?, Token-2022 transfer tax, top-holder concentration, plus a live buy->sell round trip via Jupiter as a strong signal the token is sellable at scan time (catches most honeypots). Returns a 0-100 risk score, machine flags and an agent-readable verdict (AVOID/CAUTION/LOW RISK). For snipers, wallets and trading agents vetting a token before buying.
thomenz.me-$0.005listed
Solana DeFi Intelligence
Deployer reputation for a Solana token: traces the mint's creator wallet, how much of the token the deployer still holds, the deployer wallet's age and the token's age. Returns a 0-100 risk score + verdict flagging fresh wallets, heavy insider self-holding and brand-new tokens. Answers 'who launched this and should I trust them?' before you buy. For snipers and trading agents.
thomenz.me-$0.01listed
Solana DeFi Intelligence
Liquidity durability / rug-pull exposure for a Solana token. Reports its pools (TVL, age, DEX), largest-pool depth, burned-supply share, and whether mint/freeze authority is still live (dilution/freeze risk). Returns a 0-100 liquidity-risk score + verdict (DURABLE/SHAKY/FRAGILE/RUG-PRONE): how sticky the liquidity is and whether a dev could pull it. A durability signal, not a cryptographic LP time-lock proof. For LPs and snipers.

Spend Permission Auditor
🆕 Base Account spend permissions let an app or agent spend a scoped, recurring allowance from a wallet — the primitive behind autonomous agent payments on Base. This reconstructs a wallet's ACTIVE spend permissions from onchain approve/revoke events and flags the dangerous ones: unlimited allowance, no expiry, unrecognized spender. The Base-native, agent-era drain check that ERC-20 approval tools can't see.
