How this service works
Gas, balances, token data, address type, approvals, transaction decoding, x402 receipt verification and verifiable randomness on Base, Arbitrum, Ethereum and Optimism. No API key: pay $0.001-$0.01 per call in USDC on Base via x402.
Output
Returns a JSON object with the host's bazaar membership status, total resource count, a list of individual resources each with their USD price and 30-day payer count, and aggregate 30-day call and payer statistics.
Example use cases
Discover available chain data endpoints
“I want to use Plainchain to get on-chain data but I'm not sure what api.onesource.io actually provides — can you list all their resources and what each one costs?”
Compare provider usage before calling
“Before I start making pay-per-call requests, check how many people have been using plainchain.appin60.com's endpoints in the last 30 days so I can gauge reliability.”
Verify host is in the Plainchain bazaar
“Is the host chain.myprovider.io listed in the Plainchain bazaar? I want to confirm it's registered and see what resources it exposes before my agent starts paying for calls.”
Technical details
Endpoint
GEThttps://plainchain.appin60.com/v1/bazaar/host?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover what specific blockchain data resources a known Plainchain host exposes, their prices, and their usage before committing to individual data calls. Prefer this over general blockchain RPC discovery when the host is known to be a Plainchain-compatible bazaar provider.
Side effects
- Missing or invalid 'host' query parameter returns a validation error
- Host not found in the bazaar returns inBazaar: false with empty items list
- Network timeout if the Plainchain service is unavailable
- x402 payment failure if USDC balance on Base is insufficient
