# OnchainPulse Yield Reality Check

> OnchainPulse Yield Reality Check is a paid API for AI agents from onchainpulse.theaslangroupllc.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Validates dividend and reflection token yield claims by computing actual daily reward pool from live 24h DEX volume × tax rate × payout share, issuing a VOLUME-BACKED / STRETCHED / FANTASY verdict and flagging copycat tokens.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability onchainpulse-yield-reality-check-4619a649
```

Example prompt: Can you reality-check the yield claims for this reflection token at 0xA8b919680172417e5b7b2D5c0f43B879bA1b4f3 — the project says there's a 5% transaction tax with 80% going to holders, and they're promising $10,000 a day to the pool. My wallet holds 0.01% of supply. Is that mathematically backed by real volume?

## When to prefer this

Choose this endpoint when you need a deterministic, math-first reality check on whether a tax-redistribution, reflection, or dividend token's yield promises are mathematically supportable by actual on-chain trading volume. It is specifically designed for tokenomics validation and is not an LLM-based opinion — use it over general token safety scanners (like /api/evmtoken) when the core question is 'is this yield claim real?' rather than 'is this contract safe?'. Best paired with a contract safety endpoint for full due diligence.

## Known failure modes

- Token contract address not found or unsupported chain — returns error with chain compatibility note
- No DEX liquidity or trading volume in the past 24h — cannot compute reward pool, returns null volume warning
- Invalid or non-EVM address format provided — schema validation error
- Tax percentage or payout share parameters outside plausible range — may return warning or reject
- Token has no reflection/tax mechanism detectable on-chain — verdict may default to FANTASY with explanation
- Rate limiting or upstream DEX data unavailability — may return stale or partial data

## How this service works

Reality check on dividend and reflection token yield claims, deterministic. For any tax-redistribution token (gold dividends, USDT rewards, reflections): live 24h DEX volume x tax rate x payout share = the ACTUAL daily reward pool, compared against the promised figure, with a VOLUME-BACKED / STRETCHED / FANTASY verdict and the required-volume multiple. Also flags same-symbol copycat tokens on other chains. No LLM. Pair with /api/evmtoken: contract safety and yield math are different questions.

## Output

Returns the mathematically computed actual daily reward pool in USD (live 24h DEX volume × stated tax rate × payout share), a VOLUME-BACKED / STRETCHED / FANTASY verdict indicating how the promised figure compares to the real one, the required-volume multiple (how many times current volume would need to multiply to support the promise), optional per-holder daily reward based on holding percentage, and flags for same-symbol copycat tokens detected on other chains.
