Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Audit an x402-gated endpoint by probing its 402 envelope, agent-card.json, well-known surfaces, and response headers. Returns a closed-vocabulary verdict plus 3-7 scored recommendations across pricing, bundling, discoverability, envelope correctness, rate limiting, tier expansion, facilitator choice, and schema clarity. Each recommendation cites the observed current-state value as evidence.
Public HTTP(S) URL of the x402-gated endpoint to audit. Must respond with an HTTP 402 envelope on an unauthenticated GET (or POST). Example: https://x402.org or any /api/tools/<slug> on a deployed x402 service.
Optional estimate of how many paid calls per month the endpoint currently receives. Used to scale recommendation impact_usd_per_month from a per-call delta to a monthly figure. Defaults to 1000 if omitted.

}Returns a ranked, deadline-aware list of open Base ecosystem funding programs (grants, accelerators, hackathons, retro-funding). Each result cites source_url, deadline, funding_range_usd, and last_verified_at. Stale entries are flagged. Designed for agents and builders shipping on Base who need a single call to surface the next applicable funding deadline.

| category* | string | Project category. Used to match grant program eligibility and scope. 'ai-agent' covers agent infrastructure, autonomous agents, and agent-economy projects; 'tooling' covers dev tools and SDKs; 'any' returns programs that accept all categories. Required. |
| max_results | integer | Maximum number of ranked program results to return. Programs are scored by match against category, stage, has_live_base_contract, and deadline proximity. Defaults to 10. |
