feat(connectors): add particle connector (7 endpoints)

Openlnecheleswants to merge intofrom

Particle connector: podcast intelligence, 7 endpoints

Particle transcribes, diarizes and speaker-identifies 160,000+ podcasts, new episodes within minutes of airing, and exposes transcripts, entity mentions, guest expertise, sponsorship data and rankings over a REST API. There is no podcast-data provider in the catalog today; this adds the first slice, chosen so an agent can go name → show → episodes → dialogue → transcript, and name → entity → mentions.

Model

  • X-API-Key auth via presets.auth.header, base URL https://api.particle.pro, 60 s timeouts, headroom over the engine's 30 s default for full-transcript reads (a few hundred KB); the recorded calls all answered in under a second.
  • One pool default in US dollars, pinned from Particle's published list prices (particle.pro/pricing, "Endpoint List Prices", Individual column, 2026-10-29): what an API-key account pays per call beyond its monthly bundle, on any plan. Provider-level PER_CALL $0.003; the costlier endpoints override only the amount. The OpenAPI x-payment-info.price on each operation is the keyless x402/MPP rate card, about 3x list, which a keyed account never pays, so it is not the pin. No usage.consolidate: no response body carries a receipt.
  • Provider-level output.fromError digests Particle's RFC 7807 problem+json (error_code, detail, resolve.message), raw envelope kept under raw.
  • New category leaf podcasts in connectors/categories.ts.
  • Fixtures recorded live on 2026-10-28 with a real key: one happy chain per endpoint plus one recorded 401 replayed per endpoint, trimmed by the fixture diet and scrubbed.
  • OpenSpec record in openspec/changes/add-connector-particle/.

Checks

deno task check, deno task lint, deno fmt --check, deno task version:check (no contract change), and the full deno task test are green with the 22 new tests. Double compile with --frozen-meta is byte-identical.

connectors/ids.lock.json carries only the seven new ids. deno task ids:check on current main already reports pre-existing drift: 78 compiled ids missing from the lock (hunterio, keenable, litescrape, orbit, search1api, vaquill, magic-hour, and the renamed bytedance / fundable / suzanne routes) and 7 lock entries no longer compiled (the old bytedance / fundable / suzanne ids). Running --update would fold all of that into this PR, which seemed better left for its own change.

Walkthrough

Adds a Particle connector with X-API-Key authentication, per-call USD usage, and seven GET endpoints for podcast and entity data. The endpoints use strict path and query schemas. The change also adds the podcasts category, endpoint identifiers, recorded success and unauthorized fixtures, replay and gated live tests, and connector specifications.

Review comments at
@connectors/particle/endpoints/entities-search/endpoint.test.ts:
- Line 35: Add an assertion after the output.data array check that verifies the
result contains both fixture entries, so the test fails if either result is
missing.
- Around line 122-125: Remove the fixed usage amount assertion from the live
test and retain shape-based checks, such as the existing data-array assertion.
Leave the replay’s local rate-card verification unchanged.

Review comments at @connectors/particle/endpoints/entities-search/endpoint.ts:
- Around line 16-18: Update the customer-facing match_quality description in the
entities-search endpoint to include the recorded strong value alongside the
listed qualities, keeping the existing description intact.

Review comments at
@connectors/particle/endpoints/episode-transcript/endpoint.test.ts:
- Around line 48-51: Update the transcript output assertion in the test to
compare the complete result.output with fixture.calls[0].res.body, ensuring the
output matches the recorded response rather than merely being a non-null object.
- Around line 122-125: Update the live test assertion on result to verify that
result.output contains a non-empty lines array, so a successful response without
transcript lines fails the test. Replace the fixed usage amount assertion with
this transcript-shape check.

Review comments at
@connectors/particle/endpoints/episodes-search/endpoint.test.ts:
- Line 37: Update the happy-path assertion in the test to verify that
output.data contains exactly two results, matching the fixture count, while
preserving the existing array check.
- Around line 142-145: Remove the fixed credit amount from the live assertion in
the `episodes-search` test. Keep the separate response-shape assertion, and
leave rate validation to the replay test.

Review comments at @connectors/particle/endpoints/mentions/endpoint.test.ts:
- Line 33: Update the happy-path test to assert that output.data contains
exactly two entries, matching happy-mentions.json, while retaining the existing
array assertion.
- Around line 122-125: Update the live test around the result usage assertion to
avoid pinning specific credit amounts; preserve shape checks for the response,
including validating that result.output.data is an array.

Review comments at
@connectors/particle/endpoints/podcast-episodes/endpoint.test.ts:
- Line 39: Update the output.data assertion in this podcast episodes test to
verify its length matches the fixture’s two episodes, so an empty or incomplete
result fails.
- Around line 119-122: Update the live test’s usage assertion to check only the
response evidence, removing the hard-coded credit amount. Keep the price
assertion in the replay test.

Review comments at
@connectors/particle/endpoints/podcast-episodes/schema/inputs.ts:
- Line 16: Update the q field in the podcast episode input schema to enforce a
maximum length of 200 characters, so longer queries are rejected as invalid
input before reaching the vendor.

Review comments at @connectors/particle/endpoints/podcast-get/endpoint.test.ts:
- Around line 118-121: Remove the amount-based result.usage assertion from the
live test, keeping its shape assertions; retain the amount assertion in the
replay test.

Review comments at
@connectors/particle/endpoints/podcasts-search/endpoint.test.ts:
- Around line 174-177: Update the live test assertion on result.usage to verify
its structure without pinning the default credit amount; keep the exact amount
assertion in the replay test unchanged.
- Around line 83-87: Update the happy-path assertion in the endpoint test to
verify that output.data contains both podcasts recorded in the fixture, while
preserving the existing type and slug assertions.

Review comments at
@connectors/particle/endpoints/podcasts-search/schema/inputs.ts:
- Line 11: Update the input schema constraints in the podcasts search schema:
cap q at 200 characters, constrain episode lengths to 0–10080 minutes, and
require cadence values and min_analyzed_guest_appearances to be non-negative,
using the vendor-published minimum and maximum bounds.

Review comments at @connectors/particle/schema/common.ts:
- Line 39: Update the guest-filter schemas in the common schema definition,
including guest_occupation and its adjacent filter field, to enforce a maximum
length of 200 characters on both strings while preserving their existing
validation and descriptions.

Rate card repinned in f1f86cf to Particle's published list prices (particle.pro/pricing → "Endpoint List Prices", Individual column, 2026-10-29): $0.003 for podcasts/search, podcasts/{id} and entities/search; $0.01 for podcasts/{id}/episodes, podcasts/episodes/search and podcasts/episodes/{id}/transcript; $0.015 for podcasts/mentions. The amounts first pinned were the OpenAPI x-payment-info prices, which are Particle's keyless x402/MPP rate card (about 3x list) and not what an API-key account pays. Tests, OpenSpec docs and the PR description are updated to match.
