Otto AI Token Score
x402
Otto AI Token Score is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns a composite 0-100 market structure score for a Base ERC-20 token, derived from seven weighted factors including liquidity, holder concentration, volume, age, pool breadth, and price stability.

How this service works
Token score by contract address — one 0-100 composite of a Base token market structure from seven weighted factors: USD liquidity, holder concentration, holder count, 24h volume, market age, pool breadth and price stability. Every sub-score, weight, raw input, source plane and read time comes back with the number, plus the full breakpoint curve, so the score can be recomputed from the response. A factor whose data plane is unavailable is reporte…
Output
Returns a JSON object with: a composite 0-100 score and band label (e.g. 'high'), an array of seven factor objects each containing key, raw input value, sub-score, weight, data plane name, and read timestamp, a formula object with the full breakpoint curves so the score can be independently recomputed, coverage metadata (how many factors were present, total weight coverage), token context fields (FDV, market cap, price, 24h volume, holder count, pool count, top-10 supply percent), caveats, a methodology URL, and a generatedAt timestamp.
Example use cases
Vet a new Base token before buying
“Before I ape into this token, can you pull the Otto AI market structure score for Base contract 0x532f27101965dd16442e59d40670fac45d143f5e and tell me if the liquidity and holder concentration look healthy?”
Compare token quality for portfolio selection
“I'm choosing between two Base tokens — run the market structure score on 0x532f27101965dd16442e59d40670fac45d143f5e and tell me its score band, volume score, and how much of the supply the top 10 holders control.”
Monitor a token's structural health over time
“Check the current composite score for Base token 0x532f27101965dd16442e59d40670fac45d143f5e and break down which of the seven factors are dragging the score down versus contributing positively.”
Technical details
Endpoint
GEThttps://x402.ottoai.services/token-scoreWhen to prefer
Use this endpoint when you need a structured, auditable, multi-factor market quality score for a specific Base ERC-20 token identified by contract address. Prefer it over generic token price endpoints when you need more than price — specifically liquidity depth, holder distribution, pool breadth, and price stability combined into a single comparable number. It is especially valuable when comparing tokens, screening for rug-pull risk, or justifying a position programmatically, because the full breakpoint curves and sub-scores make the composite reproducible and explainable. Use the contract address form (not ticker) to avoid cross-chain resolution ambiguity.
Side effects
- Invalid or non-Base contract address returns an error — only Base (chain 8453) ERC-20 addresses accepted
- Token not found in any data plane — score may be withheld (scoreWithheldReason non-null) if weight coverage falls below 0.5 minimum
- Partial data plane outage returns degraded:true in meta; affected factors marked present:false with absenceReason
- Stale or unavailable pool data causes liquidity/volume factors to be absent, reducing coverage
- Ticker symbol passed instead of contract address will fail — use /token-price sibling for symbol resolution first
