Native coin balance (ETH, MATIC...) for any address, on Base, Ethereum, Polygon, Arbitrum or Optimism. Flat price, no rate limits, no API key. Via eth_getBalance.

Read-only JSON-RPC access to Robinhood Chain, an Arbitrum Orbit L2 with ETH gas and ~0.1s blocks, served by the Pocket Network decentralised supplier set. Pay per request in USDC; no account, no API key.

A researched answer in ONE paid call: a live web search plus the top 3 results rendered to clean markdown. The single-call route costs four payments and four settlement waits; this is the same work in one payment, seconds faster and cheaper than the parts. Charged only if the search succeeds AND at least one page renders — a failed research costs nothing. Pages cap at 60KB each; unrendered runners-up are listed too.

Base send endpoint. This specific request will send 950000 token atomics to 0x430F4BA3ffDa98ea1814A2fDb3368e6c26f2fc54 on base for token 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913. For Base USDC with 6 decimals, 0.001 USDC = 1000 atomics and 1000 atomics is the practical minimum.

Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche. Cheapest token safety check before you trade; upgrade to /api/evmtoken ($0.015) for the fused CLEAR/CAUTION/AVOID verdict. Answers: is this token safe?

Cheapest-model router: send your token workload and get every current LLM ranked by estimated USD cost, with per-MTok prices, cached-input rates, and context windows. Merges the weekly hand-verified llm-pricing table (every figure carrying its official source URL and verification date) with the daily OpenRouter marketplace catalog — 400+ models — and marks each row `operator-verified` or `marketplace-listed`; `verified_only=1` keeps just the first kind. Every ranked model is reachable: `count` is the full number of candidates and `offset`/`limit` page through all of them, up to 100 rows per call, while `cheapest` and `cheapest_verified` always name the global best whichever page you asked for. `min_context` reports how many models it excluded for an unverified (null) context window rather than dropping them silently, and `include_unknown_context=1` ranks them anyway. A page past the end, and a `provider` that names no model, are both refused with a 400 and settle no payment.
