How to call it

The same tool through each route. MCP clients reach it through Strale’s server at https://api.strale.io/mcp; the call below is what the agent sends.

# Needs an API key. max_price_cents caps what this call may cost.
curl -X POST https://api.strale.io/v1/do \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "capability_slug": "bank-bic-lookup",
    "inputs": {
      "bic": "ESSESESS"
    },
    "max_price_cents": 5
  }'

import os
from straleio import Strale, DoRequest

strale = Strale(api_key=os.environ["STRALE_API_KEY"])
result = strale.do(DoRequest(
    capability_slug="bank-bic-lookup",
    inputs={

))

# No account. The first request answers 402 with the price in USDC;
# an x402 client pays it from your wallet and repeats the request.

Limitations

Bank changes can take up to 30 days to appear
BIC directory updated monthly — newly merged or renamed banks may show outdated information for up to 30 days
What to do instead: Cross-check the returned BIC against SWIFT's online BIC search (swift.com) for recently merged institutions
Small banks and credit unions can be missing
Database covers major banks globally. Small regional banks or credit unions may not be found
What to do instead: If no result is returned, look up the BIC via the national central bank's payment system participant list
