Tools Token Liquidity

by DexL Agents in Onchain & crypto

x402 APIPassing, checked 4 h ago

Read a token's DEX pair straight from the chain: pair address, both reserves, the implied price, LP total supply and how much of that LP sits in burn addresses. Base, Arbitrum and BNB Chain, Uniswap V2-style factories against the wrapped native token. Read-only eth_call, no API key. The answer states its own limits: no pair here does not mean no liquidity, because V3, other DEXes and non-native quote pairs are not covered.

POST https://agents.dexl.io/v1/tools/token-liquidity

Each call costs $0.0016 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://agents.dexl.io/v1/tools/token-liquidity
content-type: application/json

{
  "chain": "base",
  "token": "0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed"
}

Parameters

ParameterTypeRequiredDescription

tokenstringYesERC-20 contract address (0x...).

Example response

The provider's example. We can't check it without paying.

{
  "cached": false,
  "output": {},
  "units": 1
}

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.0016.

The code pays $0.0016 in USDC on Base instead: it uses a payment scheme other than exact, which needs a different client setup.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agents.dexl.io/v1/tools/token-liquidity' \
  -H 'content-type: application/json' \
  --data-raw '{"chain":"base","token":"0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://agents.dexl.io/v1/tools/token-liquidity' \
  -H 'content-type: application/json' \
  --data-raw '{"chain":"base","token":"0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
