Grey Ridge Signals — x402 Data & Security APIs

https://api.greyridgesignals.ai/.well-known/x402

Our Verdict

Our AI team checked this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

How we check →

Pay-per-call DeFi/market-data and token-safety APIs: pre-trade swap-safety gate `/gate/swap` (GO/HOLD/BLOCK — honeypot sell-sim, transfer tax, liquidity depth, admin-control flags) and `/chain/token-report` (SAFE/CAUTION/AVOID), plus Chainlink prices, crypto funding rates, DeFi yields, prediction-market data, and an MCP tool-poisoning scan. $0.001–$0.05 USDC on Base, Polygon or Arbitrum. Example: `GET /gate/swap?token=0x4200000000000000000000000000000000000006&side=buy&notional_usd=100` (free preview: `/gate/swap/preview`). ([OpenAPI](https://api.greyridgesignals.ai/openapi.json))

Rater Grades

No independent rater grade published for this entry yet. What we publish is above: who read it, and whether its endpoint answered on a date we can show. Neither is a measurement of what it returns after payment.

Embed Your Listing

Copy a snippet. The badge and the card render live from this page, so they stay current — and they say what we actually found, not that you passed something. If we ever knock your endpoint and it stops answering, the embed changes on its own. That is the point of it.
