Decision procedure for agents buying media generation pay-per-request: when to pay an image, video, or audio generation API versus free tiers or self-hosted open models. Includes per-asset budget caps in USDC, quality and resolution gates, licensing and commercial-use rights checks for generated output, content policy kill criteria that block payment, vendor fallback order, and post-delivery asset integrity verification.

Solana meme coin quality-volume radar. Returns trending tokens ranked by a quality score that rewards organic buy pressure, liquidity depth, and volume consistency. Filters out low-liquidity rugs. Use for meme coin discovery, social-momentum confirmation, or pump detection. Data: DexScreener free API; no API key required.

Solana rug check for agents evaluating a token before buying: mint authority, freeze authority, holder concentration, and liquidity depth rolled into a composite 0-100 score. Accepts USDC on Base or Solana. Category: data.

Base send endpoint. This specific request will send 500000 token atomics to 0x1234567890123456789012345678901234567890 on base for token 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913. For Base USDC with 6 decimals, 0.001 USDC = 1000 atomics and 1000 atomics is the practical minimum.

SYNTHORA Onchain Primitives: multichain (Base/Ethereum/Polygon/Arbitrum/Optimism) transaction receipts, tx lookup, wallet nonce, contract/proxy (EIP-1967) detection, ENS resolution, ERC20 + native balances, contract introspection. Deterministic, Ed25519-signed. 0.001 USDC via x402 on Base. First 3 calls FREE per wallet — send header 'X-WALLET: 0x<your Base address>' (no payment); after that 0.001 USDC per call.

Transcribe a YouTube video by URL on Venice, paid per request in USDC on Base via x402, no API key. Standalone — send a video URL; no model lookup required.

Crypto off-ramp API entry point: sell USDC or other stablecoin and cash out to a bank account in 80+ currencies. Alias of /quote. Pass targetCurrency (ISO 4217) and sourceAmount (USD) to get an FX quote, fees, the fiat amount the recipient receives, and a quoteId to lock the rate. Start here to convert crypto to fiat, then use /requirements, /recipients, /transfer, and /confirm-transfer to complete the bank payout. Pay 0.01 USDC.

Returns the current nonce (confirmed transaction count) and pending nonce for any EVM wallet address. Supports Ethereum, Base, Polygon, Arbitrum, and Optimism. Use the pending nonce when building new transactions. $0.002/call — 33% below comparable market rate.

Combined DeFi yield intelligence and market momentum in one call — 33% cheaper than separate yield-farming-active + market-movers calls ($0.009). Returns top yield pools from DeFiLlama, crypto and equity market movers, and a cross-signal layer that flags 'boosted' pools (high APY + rising token) vs 'at_risk' pools (high APY + falling token). Use for capital allocation decisions, pre-trade DeFi context, and portfolio rebalancing signals.

Complete ERC20 token state in one call: name, symbol, decimals, total supply (raw + formatted), wallet balance, and allowance. Collapses four onesource chain calls (total-supply + erc20-balance + allowance + contract — 155–229 payers each) into one $0.007 payment — 36% below the $0.011 combined chain. Supports Ethereum (default), Base, Polygon, Arbitrum. No API key required.

DeFi research pack: returns TVL, chain breakdown, fees, and native token price for 1–3 protocols in one call. Collapses the defillama-protocol + defillama-coin-price 2-call chain at 70% of combined cost ($0.034→$0.024). Same DefiLlama upstreams, zero auth.

Tavily API proxy — search. JSON body matches https://docs.tavily.com/documentation/api-reference/introduction. Poll GET routes (research status, usage) are free; POST routes are x402. $0.042 USDC per request.

Tavily search-lite — one x402 POST proxies Tavily Search API. $0.042 USDC per request. Entry SKU. Agent search: search lite, serp, tavily, web search, semantic search.

Name a gated data product — get its decomposition. For procurement, research and buying agents evaluating $1k–$200k/yr data subscriptions: what the product actually adds vs the free public sources under it, exact upstream datasets with licenses, a rebuild recipe, per-call price math, the licensing traps (non-commercial APIs, scraping judgments, live litigation), and the pay-per-call alternative where one exists. Curated research, not generated guesses; honest when a moat is real.

Due-diligence check on any domain: registration age via RDAP, registrar, DNS posture (A/MX/NS), SPF and DMARC presence, SSL certificate history, and risk flags like newly-registered or no-mail-setup. One call, one JSON verdict. $0.008 USDC per call, pay via x402, no API key.

GPU compute price arbitrage — ONE $0.25 call returns live $/GPU-hour for one GPU class (H100, H200, B200, A100, L40S, RTX 4090/5090) across the vast.ai marketplace floor, RunPod community/secure cloud, and the AWS on-demand anchor, plus the spread multiple and 24/7 monthly savings versus the anchor. Marketplace-vs-hyperscaler spreads of 3-4x are routine in 2026 — for agents provisioning training or inference this is direct spend recovery. Live provider APIs, no LLM in the path.

Reads eth_feeHistory over the last ten blocks with reward percentiles 25, 50 and 75, and falls back to eth_gasPrice when a node does not serve fee history. base_fee_gwei is the base fee of the next block, not of the last one, because that is the fee a transaction sent now will actually pay. recommended_gwei is a bid, not an observation: priority at the median plus a base fee doubled to survive several full blocks, and the rule is stated in recommended_rule. cost_usd converts that into dollars fo

Provision a persistent Stacktree API key ($1.00). The key is returned once in the response body.

Remove an image background for $0.002 USDC. Send one bounded base64 PNG, JPEG, or WebP; get a durable transparent PNG and SHA-256 receipt. No API key, subscription, URL fetch, or retained input.

Stablecoin remittance rail comparison: USDC and USDT on Base, Solana, and Tron versus Wise, Western Union, and banks for any send-receive corridor. Total cost including on-ramp, network fee, and the real off-ramp spread to cash in the destination country. Honest about where the receiving-country cash-out is thin, expensive, or gray-area. Worldwide corridors.
