Live data feeds for AI assistants — fresh data your model doesn't have on its own. Four feeds over a remote MCP endpoint: current LLM pricing & capabilities (~250 models), a searchable MCP server registry, real-time up/down status for major AI & dev services, and the latest AI news/releases. Free tier available.

A marketplace where autonomous agents discover, pay for, and buy live data and scientific capabilities over Bitcoin Lightning.

Marketplace for agent-purchasable capabilities. Every listing carries a falsifiable acceptance predicate; payment settles only when the predicate passes against the real result.

OFAC SDN and Consolidated sanctions name/identifier candidate evidence with source versions; Exact PyPI/npm version vulnerability checks with advisory, fix and CISA known-exploitation evidence; response schema and declared-freshness checks with advisory supplied-evidence assessment; feed inspection and normalization, PyPI/npm package identity, conservative JSON repair and YAML conversion, public TLS certificate diagnostics, timezone-aware cron calculations; Technical page SEO checks, dated currency reference conversions, VIN decoding, passive HTTP security/CORS checks and link/sitemap inventories; SEC filing lookup, URL and redirect inspection, static page metadata, QR code generation and cryptographic digests; academic paper search with deduplicated identifiers and provenance, private temporary email inboxes, paid API listing monitoring, task-routed model inference, dated topic news search, x402 service diagnostics, annual SEC financial facts, CSV validation, citation-source comparison, web extraction and email domain checks for agents. Find recent topic news with deduplicated source links and optional source-linked headline highlights; retrieve six annual US-GAAP USD fields by CIK with filing links, same-filing growth checks and optional observed revisions; check supplied CSV and citations; extract public page text, rendering JavaScript in a headless browser when needed; inspect email address syntax and mail-domain DNS. Pay per call with native USDC on Base or Solana via x402, without a separate API key. Wallet-first free trials cover CSV, column-spec, citation and static-page operations.

Research, inference, data/web/email tools, and x402 conformance, service catalog and grade feeds.

Discover SEC facts, CSV/citation checks, web extraction, mail DNS and x402 conformance scans.

Find and use Mekler pay-per-call services for agents. Search the service catalog by task, then read complete inputs, examples, exclusions, prices and recovery instructions before payment. Services include model inference, academic paper and news search, financial facts, CSV validation, citation checks, web text extraction, email checks, agent inboxes, listing monitoring, QR images, document digests and metadata. Service Conformance diagnoses public x402 origins with separate linter and compliance grades plus bounded ecosystem evidence. Browse scanned listings and history, manage verified domain ownership and visibility, buy a complete listing export for 0.25 USDC, or read incremental grade events for 0.01 USDC per page. External evidence is labeled and does not prove paid delivery. Use search_services and get_service for current contracts. Pay per use via x402 on Base or Solana; the MCP server never signs payments. Wallet-signature trials cover eligible operations. Docs: https://api.mekler.ai/llms.txt · Pricing: https://api.mekler.ai/pricing · OpenAPI: https://api.mekler.ai/openapi.json

Per-byte data feeds & oracles for AI agents: pay-per-call in USDC on Base mainnet over x402 (no API key, no token), or subscribe to first-party feeds across markets, weather, threat-intel and legal — plus decision oracles (address-reputation, sanctions screening). 15 MCP tools incl. `byte_buy_data` (one-off via the gateway at https://x402.payperbyte.io/feeds); priced per feed in USDC (flagship $0.05 address-reputation). Every paid response emits an EIP-712 PayloadAttestation; subscribers re-derive keccak256 over received bytes and recover the signer before trusting it — fails closed on tamper. Attestation domain anchored on Arbitrum Sepolia (audit-gated for mainnet). ([npm](https://www.npmjs.com/package/byte-mcp-server)) ([Smithery](https://smithery.ai/servers/byte/byte-library)) ([MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.0rkz/byte-protocol))

PayPerByte — verified, provenance-first per-byte data for AI agents. 15 tools to discover feeds, pay-per-call over x402 (USDC on Base mainnet, no API key, no token), and verify every payload against its EIP-712 PayloadAttestation before acting. Flagship: the $0.05 address-reputation go/no-go verdict. npm `[email protected]`. (On-chain attestation domain anchored on Arbitrum Sepolia; mainnet anchor audit-gated.)

USDC data feeds + oracles for AI agents — pay-per-call via x402, settled in USDC on Base. Data responses carry an EIP-712 PayloadAttestation receipt (X-BYTE-Attestation) you verify before acting; the attestation domain is anchored on Arbitrum (chainId 421614) regardless of settlement rail. Each feed has a fixed per-call price, not metered by payload size — the exact USDC amount is listed per feed
