Pass/Fail before you waste budget on a doomed call. Decide whether to make a paid LLM call before you make it. Preflight scores your prompt against an 8-dimension quality rubric (pass/fail at 28/80) and optionally pulls the target endpoint's on-chain trust signals — total payments, unique payers, last activity. Two-in-one circuit breaker for agents that don't want to waste budget on weak prompts or sketchy endpoints. (rev 2)

Tiny paid pre-payment oracle for one x402 endpoint: returns pay/block/cap verdict first, warnings and exact 402 term checks second, then execution policy, replay/binding checks, and seller fix appendix. Free preview includes paid_request_body + preview_id; paid route is now $0.03 to match try-it conversion pricing. Price 0.03 USDC on Base via x402. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/endpoint_risk. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.

Real-time stock price quotes for one or more ticker symbols. Returns price, % change, 52-week high/low, exchange, and currency.

Timezone lookup by coordinates, IP address, or country code/name. Includes country details.

Current weather conditions and multi-day forecast for any location. Powered by Open-Meteo.

Avoid paying unsafe x402 endpoints: ranked safe alternatives for the same capability.

Pre-flight integrity check for any text your agent processes or publishes. Catches prompt injection, invisible Unicode, homoglyphs, and LLM watermarks, the silent failures most pipelines ship past. POST text, get clean text plus flags and a risk score. Sub-50ms, deterministic, cacheable.

VERIFIABLE keyless web-read for autonomous agents. Every result ships a cryptographically SIGNED provenance receipt (EIP-191 over sha256(text)+url+status+time) — the wedge a free scraper structurally CANNOT match: Jina r.jina.ai is free+keyless too, but its bytes are HEARSAY (no proof of what/where/when). MERCURY's `attestation` is ecrecoverable OFFLINE, forever, by you OR any downstream agent you forward the bytes to — proving the content is genuine + untampered (key pinned at /.well-known/mercury-attestation). For RAG, trading and agent-to-agent commerce that need provenance, that is the gap between data and evidence. Beyond that it's the keyless web-read primitive — NO API key, NO signup, NO account, NO monthly plan, the one fetch SKU a fresh agent can onboard to by itself instead of stopping to ask a human for a key. Give a ?url= and get back clean readable page text + title + status. Agent-native extras (opt-in): ?format=markdown for structure-preserving markdown, ?links=1 for an outbound-link graph (crawl frontier), and the headline wedge — STRUCTURED EXTRACT: ?extract=title,price,author,publishedAt returns a clean JSON record { title, price, author, publishedAt }, an LLM-ready row not a wall of text. That is Firecrawl's paid 'JSON mode' (they need an LLM call + an API key for it) done here DETERMINISTICALLY from the page's own JSON-LD/OpenGraph/meta/microdata — keyless, no LLM, $0.003. (?extract=1 still returns the legacy description + wordCount.) The extracted record is folded into the SIGNED attestation too, so a buyer can prove the FIELDS — not just the raw bytes — are exactly what MERCURY resolved. You pay in-band over HTTP 402 (x402, USDC on Base mainnet) — the wedge those tools can't match: they ALL gate behind a human-created API key + a credit-card plan, so an agent can't onboard itself. This one an agent finds in the x402 Bazaar and pays with zero human in the loop. Honest charge-per-ATTEMPT: every call returns a structured result (success OR an ok:false failure with a reason) — never a silent charge-then-500. Follows redirects, SSRF-guarded, 5s timeout, 10MB cap. Pure data, no mint — delivers in prod.
