USDC micropayments · x402 v2

Trading data that agents can buy per request

No subscription, sales call or CoinVerum API key. Pay only for the Ethereum on-chain signal you request, receive JSON, and keep the on-chain payment receipt.

Last updated: August 31, 2026

○ Mainnet activation pending

The API and pricing catalog are deployed. Paid resources stay closed until the receiver wallet and production facilitator credentials are activated.

Built from CoinVerum's own index

The paid layer combines indexed swaps, complete on-chain pool state, liquidity history and lending risk. It does not repackage DEX Screener or CoinGecko responses.

How a request works

  1. Call a premium endpoint normally.
  2. The API returns HTTP 402 and a standard PAYMENT-REQUIRED challenge.
  3. Your x402 client authorizes the advertised USDC amount on Base.
  4. Retry with PAYMENT-SIGNATURE; CoinVerum verifies, returns data and settles.
  5. Read PAYMENT-RESPONSE for the public settlement transaction.
# Inspect the machine-readable catalog curl https://api.coinverum.com/x402 # An unpaid request returns 402 plus PAYMENT-REQUIRED curl -i https://api.coinverum.com/x402/v1/token/0x111111111117dc0aa78b770fa6a738034120c302/execution

Why these signals are paid

Commodity price and pool lookups are already widely available for free. CoinVerum charges for the computation traders and autonomous agents otherwise have to build themselves: verified liquidity deltas, direction-aware large-flow aggregation, execution-loss models, price dispersion and cross-protocol liquidation context.

Data guarantees and limits

  • Every response includes generation time, indexed-through time and methodology.
  • Trusted TVL requires complete on-chain balances or state and full price coverage.
  • Execution estimates clearly name included and excluded AMM models.
  • Liquidation protocols may use oracle prices that differ from DEX prices.
  • Responses are market information, not executable quotes or recommendations.
