Introducing x402 on Birdeye Data — Pay-Per-Request API Access

API access has traditionally required upfront commitment — monthly subscriptions, credit card details, account provisioning. For developers testing a new idea, for AI agents that need data autonomously, or for teams that don’t know their usage volume yet, this creates unnecessary friction.

Birdeye Data now supports x402, an open HTTP payment standard for internet-native payments, that enables instant, per-request payments using stablecoins directly over HTTP. Every API call is a transaction. No subscription required.

What is x402?

The x402 protocol brings the long-dormant HTTP 402 “Payment Required” status code to life. Instead of requiring accounts, API keys, and billing cycles, x402 lets any client, human or machine, pay for a resource at the moment they request it.

The flow is simple:

1. Client sends an API request
2. Server responds with 402 Payment Required + payment instructions
3. Client signs a stablecoin payment (USDC)
4. Server verifies payment via an on-chain facilitator (e.g., Coinbase CDP for Base, PayAI for Solana) and returns the data

No signup. No API key provisioning. No monthly invoice. Just data for payment, per request.

How Birdeye’s x402 integration works

Birdeye’s x402 Pay As You Go package provides access to Birdeye’s full REST API, the same endpoints available to standard subscribers, without requiring a subscription.

At $0.003 per request, Birdeye’s x402 pricing is competitive with the market — comparable providers charge standard subscription fees that lock agents into rigid plans.

Who this is for?

• AI agents
  This is the primary use case. Autonomous agents need data to make decisions: token prices, liquidity, trading volume, wallet balances. With x402, an AI agent can query Birdeye’s APIs and pay for each request autonomously using its own wallet. No human in the loop. No API key management. The agent pays for what it uses.

• Developers testing and prototyping
  Before committing to a monthly plan, developers can query Birdeye’s full API surface on a per-request basis. Test your integration with real data. Pay only for what you call.

• Applications with variable usage
  Some products have unpredictable data needs — spiky traffic, seasonal usage, event-driven queries. Pay-per-request removes the guesswork of choosing the right subscription tier.

What you can access

x402 gives you pay-per-request access to Birdeye’s full REST API — every endpoint, no subscription:

• Real-time token data — prices, market cap, volume, liquidity across Solana, Sui, and major EVM chains
• Trading data — live trades, OHLCV candles, buy/sell ratios, top traders
• Wallet analytics — portfolio tracking, transaction history, PnL
• Market discovery — trending tokens, new listings, gainers/losers
• Token security — safety signals, metadata, holder distribution
• New listings — newly created tokens with creation timestamps, ideal for meme and early-entry agents

The same data that powers applications at Phantom, Backpack, Raydium, and Bybit now accessible per request.

Note: WebSocket streaming is not available under x402. WebSocket access is included in standard Pro/Enterprise plans.

Getting started

Using Birdeye via x402 requires no account setup. Any x402-compatible client can start making paid API requests immediately.

For developers building x402 clients, Coinbase provides SDKs in TypeScript and Go. Full x402 documentation is available at docs.cdp.coinbase.com/x402 or the x402 Open Standard.

Birdeye Data’s x402 API reference, including supported endpoints and payment details, is available at docs.birdeye.so/reference/x402.

For teams that prefer traditional subscription access, Birdeye Data’s standard packages, including the free Standard tier, remain available at bds.birdeye.so.

Why this matters

The way applications consume data is evolving. Subscriptions assume predictable, human-driven usage. But AI agents don’t fit that model. They query when they need to, pay for what they use, and operate autonomously.

x402 aligns the payment model with how software actually works, especially in an agentic world. Birdeye Data is one of the first onchain data providers to support this model, making real-time DeFi data accessible to any agent, any developer, any application – one request at a time.

$0.003 per request. Premium data. No strings attached.
