Start Connecting APIs to Your AI Agents

Browse thousands of APIs, connect in minutes via MCP, OpenClaw, or Python. One SDK, one credential — every API your agent needs.

0x API

The 0x API v2 aggregates liquidity from on-chain DEXs and off-chain market makers across Ethereum and dozens of other EVM chains, returning the best executable price and a ready-to-sign transaction for a token swap. Two flavours are exposed: an Allowance Holder flow that uses a single approval contract, and a Permit2 flow that signs token allowances per trade. A separate Gasless endpoint set lets users trade without holding the native gas token by relaying signed messages. Designed for wallets, trading bots, and DeFi front ends that need consistent best-of-route pricing.

1Forge Finance APIs

Jentic publishes the only available OpenAPI specification for 1Forge Finance APIs, keeping it validated and agent-ready. 1Forge provides real-time forex and cryptocurrency market data through a small set of focused endpoints covering live quotes, currency conversion, supported symbol lists, and forex market status. Agents can pull bid/ask/mid prices for currency pairs such as EUR/USD or BTCUSD, convert specific amounts between currencies on demand, and check whether the forex market is currently open before placing logic. The API is designed for low-friction integration: a single API key authenticates all requests and responses are flat JSON objects.

Account and Transaction API Specification

The UK Open Banking Account and Transaction API (AISP) is the standard interface that account-information service providers use to read PSU bank data from regulated UK banks. It defines 29 endpoints covering account access consents, account lists, balances, transactions, beneficiaries, direct debits, standing orders, statements, products, and parties. The flow uses two OAuth 2.0 schemes: TPP client credentials for consent setup and PSU authorization-code SCA for resource access. Every ASPSP that complies with the standard exposes the same operations under their own /open-banking/v4.0/aisp base path.

Account and Transaction API Specification - UK

The National Bank of Greece Account and Transaction API implements the UK Open Banking Account and Transaction profile v3.1.5, providing AISP-style access to NBG retail and business accounts. Authorised third parties can request consent, list accounts, and read balances, transactions, statements, beneficiaries, parties, scheduled payments, and standing orders. The spec also exposes sandbox management endpoints for setting up and tearing down test datasets. Authentication combines OAuth 2.0 (client-credentials and authorisation-code flows) with a Client-Id header.

This NBG main spec is the canonical catalogue entry for the National Bank of Greece Account and Transaction API, implementing the UK Open Banking Account and Transaction profile v3.1.5. Authorised AISPs can read NBG accounts, balances, transactions, statements, beneficiaries, parties, scheduled payments, and standing orders, plus provision sandbox datasets for development. Authentication combines OAuth 2.0 (client-credentials and authorisation-code flows) with a Client-Id header.

The 8 endpoints cover the operational surface needed to keep a messaging or voice account funded, configured, and credentialed.

Accounting API

Apideck Accounting is a unified API that maps a single schema for invoices, bills, payments, ledger accounts, customers, suppliers, and tax rates onto many downstream accounting platforms such as Xero, QuickBooks, Sage, NetSuite, and FreshBooks. The 95 operations cover the day-to-day finance objects most apps need plus reports like Balance Sheet, Profit and Loss, and Aged Debtors. Apideck routes each call through Apideck Vault, so customer credentials for the underlying platform stay in Apideck's vault instead of being passed in by the calling app.

Accounting API

Codat's Accounting API provides a unified interface for reading and writing accounting data across 20+ accounting platforms including QuickBooks, Xero, Sage, NetSuite, and FreeAgent. It standardises invoices, bills, journal entries, customers, suppliers, payments, and financial reports so a single integration maps to all supported systems. The API supports both pull operations (read normalised data from a linked company) and push operations (create or update records back into the source ledger). It is designed for fintech applications, lending platforms, and B2B SaaS products that need accounting data from their customers' books.
