OnchainPulse Narrative-vs-Chain Consistency Check
x402
OnchainPulse Narrative-vs-Chain Consistency Check is a paid API for AI agents from onchainpulse.theaslangroupllc.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-14).
Fetches a token project's website, extracts its public claims about supply, locks, team holdings, taxes, and ownership, and cross-checks each claim against live on-chain data, labeling each as consistent, inconsistent, or unverifiable with exact numbers.

How this service works
Narrative-vs-chain consistency check — the missing layer of token due diligence: fetches the project's own website, extracts its checkable public claims (supply, locks, team holdings, taxes, ownership) and marks each one consistent / inconsistent / unverifiable against independently observed on-chain data, with the exact numbers. Pre-launch-imposter screen included (site live? trading while site dead?). Solana + 8 EVM chains incl. Base & Robinhood Chain. Facts only — no scores, no advice.
Output
A structured list of each checkable public claim extracted from the project's website (e.g. 'max supply: 1,000,000,000'), each labeled as consistent, inconsistent, or unverifiable, alongside the exact on-chain figure observed. Also includes a pre-launch imposter signal indicating whether the site is live and whether trading activity exists on-chain despite a dead or absent site. No scores or investment advice are returned — only factual comparisons.
Example use cases
Pre-investment token fact-check
“Before I buy into this new Base chain token, can you pull up their project site and check if their claims about max supply, team wallet percentages, and liquidity locks actually match what's on-chain? Flag anything inconsistent with the exact numbers.”
Rug-pull imposter site screen
“I found a token that says it's the official launch for a project but the website looks sketchy — can you check if the site is live and whether the token is already trading, and compare any supply or ownership claims against on-chain reality?”
Due diligence on stated tax/fee claims
“This Solana token says it has a 2% buy tax and 2% sell tax with no owner privileges — can you verify those claims against the actual contract on-chain and tell me if each one checks out or not?”
Technical details
Endpoint
GEThttps://onchainpulse.theaslangroupllc.com/api/narrative-checkWhen to prefer
Choose this endpoint when you need to fact-check a specific token project's stated narrative against independently observed on-chain data — especially before investing, listing, or publishing research. It is uniquely suited for catching discrepancies between marketing claims and blockchain reality (supply, locks, team holdings, taxes, ownership). Prefer it over general contract-safety scanners when the goal is narrative consistency rather than bytecode vulnerability analysis, and over generic blockchain explorers when you need automated claim extraction from the project's own website rather than manual lookup.
Side effects
- Project website unreachable or returns no extractable claims — claims list empty
- Token contract address not found on specified chain — chain or address error returned
- Chain not supported — must be Solana or one of the 8 supported EVM chains including Base and Robinhood Chain
- On-chain data temporarily unavailable for a specific field — claim marked unverifiable
- Malformed contract address — request validation error
- Website content too ambiguous to extract specific numeric claims — fields marked unverifiable
