How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
Returns a JSON object with an 'ok' boolean indicating success, a 'usd' field containing the spot price as a number, and a 'product' field set to 'pin_spot' identifying the data product.
Example use cases
DeFi portfolio valuation snapshot
“I need the current pinned spot price of WBNB in USD right now so I can value my DeFi position — fetch it from the pin-spot endpoint.”
XRP arbitrage price check
“Can you grab the spot price of XRP in USD from the pin-spot API? I want to compare it against another exchange rate I have.”
Stablecoin peg verification
“Check the pinned spot price of USDC in USD for me — I want to confirm it's still holding its peg before I execute a swap.”
Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/v1/pin-spotWhen to prefer
Choose this endpoint when you need a low-cost ($0.05 USDC), on-demand spot price for WBNB, XRP, or USDC and can pay via the x402 micropayment protocol on the Base blockchain. It is ideal for agents that already support x402 payment flows and need a quick, lightweight price oracle without subscribing to a full market data API.
Side effects
- Invalid or unsupported symbol — only WBNB, XRP, and USDC are accepted enum values
- Missing or invalid x402 payment header — returns 402 Payment Required if micropayment is not provided
- Payment on wrong network — v2 only accepts Base (eip155:8453); using BSC without legacy header causes rejection
- Missing required 'input' body object or wrong HTTP method — returns 400 Bad Request
- Upstream price feed unavailable — may return error or stale data
