Agent & Infrastructure

Trading Data API — 23 endpoints for agents: crypto & stock prices/OHLCV, ATR, Fair Value Gaps, ICT liquidity levels, funding/OI, order books, Kalshi prediction markets, DeFi TVL, volatility, macro calendar, and an AI momentum score. Full catalog at /v1/status.

Agent decision procedure for x402 payments: inputs are task goal, budget remaining, latency budget, and required confidence. Auto-pay when expected value clearly exceeds price and failure is cheap to retry. Deliberate when price is material or upstream unproven. Defer when identity, refund path, or provenance missing. Keep request id, payer policy version, evidence hash, settle receipt. Handle failure modes like empty payload, wrong schema, double-charge with idempotency keys. Demands

Evaluate caller-supplied x402 payment requirements before a wallet signs them. Use after receiving HTTP 402 to enforce a maximum USDC amount, allowed networks, exact scheme, recipient presence, and an optional expiry buffer. Returns eligible accepts and explicit blockers for 0.002 USDC via x402 on Base; it never signs, pays, stores, or echoes a payment signature.

Revalue amount by two rates (historical vs current). Call when ECB-style revaluation when rates are caller-supplied. Returns revalued_amount as deterministic JSON for $0.002 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Claim grounding and citation attestation for AI agents: verified enrichment that adds a veracity field to text. Each factual claim is grounded against live web sources (Wikipedia + world news) and returned with a machine-verified verdict (supported/refuted/unverified), a confidence score, and cited sources. Refuses to guess on conflicting evidence. Built for research agents that must cite, citation-locked content, and compliance checks.

Detect when an Apify Actor, API, scraper or data feed breaks, goes stale or silently changes shape. One paid call returns a verdict with the evidence behind it, so an agent can decide whether a data source is still trustworthy before acting on it. Works with any HTTP endpoint; 35+ pre-wired vendors (OpenAI, Anthropic, Stripe, GitHub) are a head start, not a limit. Schedule it on your own cadence for continuous monitoring of breakage, staleness and drift.

Deep endpoint trust/QoS report for an x402 endpoint. Everything the trust score returns PLUS history detail: the full payment-terms drift log (including custody/payTo changes), the discovery/listing timeline across directories, the paid-delivery sample log, and a summarized counts-by-outcome breakdown with latency percentiles. Raw per-probe rows are never shipped. Use for auditing or investigating a specific endpoint's reliability over time.

All-in-one trust intelligence for x402 services: the complete validation dataset (100+ services graded A-F with real purchase tests, on-chain proof tx hashes, response quality and a how-to-buy guide) PLUS, if you send a 'resource' URL, a fresh verification of that service (passive probe + real micro-purchase + LLM grade) included in the same response.

[BATCH+PROOF] Full x402 service demand roster, latest day: demand_class, calls_30d, unique_payers_30d, score_total, liveness_state, lifecycle, record_hash per service. Model demand-v1, refreshed daily from the public CDP catalogue; unique_payers_30d is a lower bound, never a sum. DEGRADED DELIVERY, see unavailable_fields - the five-axis sub-scores, action_hint, tier and verified are empty. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

Decision procedure for agents and their operators that answers the three questions every auditor asks after an AI agent spends money: who authorized it, what was the ceiling, and who carries the loss when the purchase is wrong. Covers cryptographic proof that an agent, not a human, executed a payment, signing intent with a held Ed25519 key before settlement so future audits can distinguish autonomous execution from manual action. Includes spend-authorization record schema, approval chain

Searches the public x402 discovery catalogue for services able to replace a broken dependency. Give the failed URL and, better still, a short description of what it did and the fields you need back; matches are scored on overlap between your task words and the candidate name, description and path, then ordered by score and price. Every hit carries the reason it matched, its price in USDC, its network and when the catalogue last saw it.

Performs the MCP handshake against a streamable-HTTP endpoint and then reads the catalogue: tools with their input schemas, resources with their URIs and mime types, and prompts with their arguments. Servers answering as an event stream are handled as well as plain JSON, and a session id is carried across calls. Only listing methods are sent — no tool of the inspected server is ever executed, nothing is written, and no resource contents are read.

Validates an Agent Card document against the A2A convention and returns findings by severity: error (the card is unusable as published), warning (works, but a consuming agent will guess), info (recommended field absent). Checked: the required fields name, description, url, version, capabilities and skills; that url is absolute and https; that every skill carries id, name, description and tags and that skill ids are unique; that declared securitySchemes use a known type and that every entry in…

Takes the steps of one agent run and returns a scored report. It counts identical tool calls (same tool, same arguments) as loops, finds the longest run of consecutive failures, marks calls whose result was empty or null as wasted, and attributes cost per step and per tool so the expensive part is visible. Cost is taken from your figures when supplied, otherwise computed from token counts against the model price table.

Higher-quality chat on Llama 3.1 8B Instruct Fast (@cf/meta/llama-3.1-8b-instruct-fast). POST messages[]; suited for reasoning-heavy turns with dynamic token pricing.

Open-web search — one x402 POST discovers SERP candidates, ranks with BGE embeddings, optional page snippets. $0.370 USDC per request. Pseudo-Exa via headless browser + semantic rank. Agent search: web search, exa, firecrawl, serp, semantic search.

A structured gap map of five open niches in Solana x402 agent payments, based on the July roundup and live market signals. Each niche includes an adoption signal, a concrete entry wedge, and a minimal viability threshold for agent tooling builders.

Call/put delta from BS closed form. Call when delta-hedging or option inventory needs BS delta. Returns delta for call and put as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Mark a position to a given price for equity snapshots. Call when portfolio marks without a live exchange feed in the tool itself. Returns position value at mark as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Advisory liq price ladder over leverage steps. Call when stressing sequential leverage reductions toward liquidation. Returns steps of approx liq prices as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

OLS hedge ratio beta of y on x (no intercept). Call when sizing the short leg in a pairs trade offline. Returns beta and n as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
